Usually I dot my laptop with READMEs in various ~/devel/ subdirs, but in this case I decided to write up some notes here. These are mostly for my own reference, but perhaps they will be of use to you.

=Package Building HOWTO= Here's how to build a "standard" ./configuresque package for Maemo 5, using "foo" as an example. This is a command line application...

Environment
First set up your initial environment in the scratchbox to save future keystrokes. This only has to be set up once.

ssh -C flauta.freemoe.org /scratchbox/login echo 'export DEBFULLNAME="Jeff Moe"' >> ~/.bashrc echo 'export DEBEMAIL="moe@blagblagblag.org"' >> ~/.bashrc . ~/.bashrc echo $DEBEMAIL ; echo $DEBFULLNAME
 * 1) log in to development/SDK server:
 * 1) Enter scratchbox
 * 1) Set up your full name for debianization (enter your name, not mine!):
 * 1) Set up email address for debianization (enter your email, not mine!):
 * 1) Re-read bashrc to drag in above:
 * 1) Check that all looks cool:

Package Setup
Now do the actual creation of the package:

mkdir -p ~/foo/freemoe cd ~/foo/freemoe wget http://foo.googlecode.com/files/foo-1.2.3.tar.bz2 tar jxf foo-1.2.3.tar.bz2 tar zcf foo-1.2.3.tar.gz foo-1.2.3 cd foo-1.2.3 less COPYING dh_make --single \ --copyright gpl \ --file ../foo-1.2.3.tar.gz echo auto > debian/optify
 * 1) Set up some dirs for workingspace:
 * 1) go there
 * 1) grab source from upstream
 * 1) Untar the source
 * 1) Upstream doesn't have .gz in this case, \
 * 2) so re-tar because the version of debhelper in Maemo 5 doesn't support .bz2 (!)
 * 1) Enter source dir
 * 1) Check WTF the LICENSE is
 * 1) Initial setup of package
 * 1) Set up for maemo-optification:

debian/control
debian/control defines info about the package that is read in such places as the application installer.


 * In the Description:, lines MUST be preceded by a space. Blank lines must have a space and then a period.


 * Check this to find a valid Section:

fakeroot apt-get update fakeroot apt-cache search bar fakeroot apt-get install bar
 * Figuring out Build-Depends: is currently left as an exercise for the reader. Hints:

Here is a sample debian/control:

Source: foo Section: user/multimedia Priority: extra Maintainer: Jeff Moe  Build-Depends: debhelper (>= 5), autotools-dev, maemo-optify Standards-Version: 3.7.2 Package: foo Architecture: any Depends: ${shlibs:Depends}, ${misc:Depends} Description: Foo does everything you want. Foo does everything. It is fantastic. . Be sure to explore all of Foo, especially the clone x-fade tool. . There is so much to Foo!

debian/changelog
Edit debian/changelog to read: foo (1.2.3-1) unstable; urgency=low * Initial release for Maemo 5 (Nokia N900). -- Jeff Moe  Tue, 22 Dec 2009 17:00:02 -0300

Generate timestamp, ala (this seems silly way to do this, but hey. UPDATE: better way pointed out by ruskie: dch -i): $ cat /home/jebba/bin/datelog echo -n " -- Jeff Moe  " date "+%a, %d %b %Y %H:%M:%S %z"
 * 1) !/bin/sh

Build Binary X86 Package
Now you're ready to actually build the package. This may help you find out what the Build-Depends: are as well.

X86
Now see if it works in x86:

sb-conf select FREMANTLE_X86 cd ~/foo/freemoe/foo-1.2.3 dpkg-buildpackage -rfakeroot -b -uc
 * 1) Switch to X86
 * 1) Go to the correct dir:
 * 1) Compile!

Optify .deb
If that all went cool, "optify" the package (am I doing this right?--I was doing it differently before, but this was recommended by upstream and is how the Maemo builder box does it):

cd ~/foo/freemoe maemo-optify-deb foo_1.2.3-1_i386.deb maemo-optify-deb foo_1.2.3-1_all.deb for i in *.deb do echo $i maemo-optify-deb $i done dpkg -c foo_1.2.3-1_i386.deb
 * 1) Go to correct dir
 * 1) Optify X86 package:
 * 1) Optify non-binary package (if any):
 * 1) Or if you have a bunch of packages and you're lazy, just
 * 1) Check optification results:

Test in scratchbox
You can test your package in the scratchbox:

fakeroot dpkg -i foo_1.2.3-1_i386.deb foo
 * 1) Install in scratchbox
 * 1) Run it!

Build Binary ARMEL Package
Now you're ready to actually build the package that will run on the phone.

ARMEL
sb-conf select FREMANTLE_ARMEL cd ~/foo/freemoe/foo-1.2.3 dpkg-buildpackage -rfakeroot -b -uc
 * 1) Switch to ARMEL
 * 1) Go to the correct dir:
 * 1) Compile!

Optify .deb
If that all went cool, "optify" the package (am I doing this right?--I was doing it differently before, but this was recommended by upstream and is how the Maemo builder box does it):

cd ~/foo/freemoe maemo-optify-deb foo_1.2.3-1_armel.deb maemo-optify-deb foo_1.2.3-1_all.deb for i in *.deb do echo $i maemo-optify-deb $i done dpkg -c foo_1.2.3-1_armel.deb
 * 1) Go to correct dir
 * 1) Optify ARMEL package:
 * 1) Optify non-binary package (if any):
 * 1) Or if you have a bunch of packages and you're lazy, just
 * 1) Check optification results:

Build Source Package
Build a source package for uploading to builder (I'm not 100% this is the optimal command, but worksforme).

cd ~/foo/freemoe/foo-1.2.3 dpkg-buildpackage -rfakeroot -S -uc -us -sa
 * 1) cd to dir

Put Package in Personal Repository
Now that it's all built and cool, copy the file over to your N900. I put it in my own repo and install it with apt on my N900. You don't have to set up a repo to do all this, but it's nice

logout mkdir -p /var/www/users/jebba/dists/unstable/main/source/foo_1.2.3-1 mkdir -p /var/www/users/jebba/dists/unstable/main/binary-armel mkdir -p /var/www/users/jebba/dists/unstable/main/binary-i386 cp -p /scratchbox/users/jebba/home/jebba/foo/freemoe/*.diff.orig.tar.gz \ /var/www/users/jebba/dists/unstable/main/source/foo_1.2.3-1/ cp -p /scratchbox/users/jebba/home/jebba/foo/freemoe/*.diff.gz \ /var/www/users/jebba/dists/unstable/main/source/foo_1.2.3-1/ cp -p /scratchbox/users/jebba/home/jebba/foo/freemoe/*.dsc \ /var/www/users/jebba/dists/unstable/main/source/foo_1.2.3-1/ cp -p /scratchbox/users/jebba/home/jebba/foo/freemoe/*.changes \ /var/www/users/jebba/dists/unstable/main/source/foo_1.2.3-1/ cp -p /scratchbox/users/jebba/home/jebba/foo/freemoe/*_armel.deb \ /var/www/users/jebba/dists/unstable/main/binary-armel/ cp -p /scratchbox/users/jebba/home/jebba/foo/freemoe/*_i386.deb \ /var/www/users/jebba/dists/unstable/main/binary-i386/ cd /var/www/users/jebba/ dpkg-scanpackages dists/unstable/main/binary-armel /dev/null \ | gzip -9c > dists/unstable/main/binary-armel/Packages.gz dpkg-scanpackages dists/unstable/main/binary-i386 /dev/null \ | gzip -9c > dists/unstable/main/binary-i386/Packages.gz dpkg-scansources dists/unstable/main/source /dev/null \ | gzip -9c > dists/unstable/main/source/Sources.gz
 * 1) Exit from scratchbox
 * 1) Create source dir on web server:
 * 1) Create binary dirs on web server:
 * 1) Copy over orig tarball:
 * 1) Copy over diff:
 * 1) Copy over dsc:
 * 1) Copy over changes:
 * 1) Copy over ARMEL binary:
 * 1) Copy over X86 binary:
 * 1) Regenerate repository headers:
 * 1) Binary ARMEL Packages
 * 1) Binary X86 Packages
 * 1) Source Packages

Install Package
Install the sucker.

Testing via manual copying
If you don't have your own personal repository, do something like this, where 10.0.0.2 is the IP address of your N900:

scp -p /scratchbox/users/jebba/home/jebba/foo/freemoe/*_armel.deb \ 10.0.0.2:MyDocs/ ssh user@10.0.0.2 sudo gainroot dpkg -i /home/user/MyDocs/foo_1.2.3-1_armel.deb
 * 1) copy file to N900
 * 1) ssh into N900
 * 1) Install .deb

Testing via personal repo
If you have your own repo, enable it, ala:

sudo gainroot vim /etc/apt/sources.list deb http://www.freemoe.org/users/jebba unstable main apt-get update -o dir::cache=/home/user/MyDocs/.apt-archive-cache apt-get install -o dir::cache=/home/user/MyDocs/.apt-archive-cache foo
 * 1) edit sources to enable personal repo:
 * 1) In my case, I add the line:
 * 1) Update repo
 * 1) Install package

Test Package
Now time to actually test it. Just run it :)

foo

Also helpful commands, like: dpkg -I foo dpkg -l foo dpkg -l | grep foo dpkg -L foo

Upload to Builder
If your package works well, time to upload to Maemo's builder to put it in extras-devel. Note, you'll need to have set up an ssh key on garage to do this.

cd /scratchbox/users/jebba/home/jebba/foo/freemoe Uh, just run this script:
 * 1) go to the dir, from outside the scratchbox
 * 2) (if your ~/.ssh key isn't in the scratchbox)

echo echo "Uploading:" ls *.tar.gz *.diff.gz *.changes *.dsc echo echo -n "All look ok? ctrl-c to quit " ; read ok echo scp -p *.tar.gz *.diff.gz *.changes *.dsc \ jebba@garage.maemo.org:/var/www/extras-devel/incoming-builder/fremantle/
 * 1) !/bin/sh

Chill
Now just wait for the package to finish. You can repeatedly hit in your browser, or ctrl-5 here:

=Debrick=

Debrick without reflashing!
I have found a way to "de-brick" a device that does not require reflashing.

If your device is booting up and hung with the second dot lit, like:

* (*)  *  *  *

this may solve your problem.

1) Get the proprietary (gah!) Nokia firmware flashing program.

2) Power off your phone.

3) Hold down "u" on your fone and plug the USB cable into your phone and your GNU/Linux laptop. This will put it in the same mode as you need when you are flashing it.

4) Run this command as root (or preface with "sudo"). It will only take a second or two.

./flasher-3.5 --enable-rd-mode

5) Unplug cables and your system will reboot (or poweroff).

6) Boot up your system, it is now in R&D mode. :) It will (possibly?) prompt you to enter time/data again.

7) Now that everything is fine, power off the system normally again. DO NOT LEAVE YOUR SYSTEM IN R&D MODE, as it eats babies.

8) With your phone powered off hold down "u" on the phone, and plug in the USB cables to the phone and your GNU/Linux laptop.

9) Run this command as root (or preface with "sudo"). It will only take a second or two.

./flasher-3.5 --disable-rd-mode

10) Unplug cables and your system will reboot (or poweroff).

11) Boot up your system, it is now recovered and NO DATA LOSS! Yippeee.

Some bugs, maybe related:  

If you found this post helpful, please vote for this bug: 

Too mucha programmaz
I bricked my N900 (December 3rd) by adding the extras-testing + extras-devel repos and then installing lots of applications. I hit 100% on / (root filesystem) and on reboot the system hung at the "dots" part, ala:

* (*) * * *

I had filled up to 100% a number of times before and rebooting the phone had cleared up space (e.g. 100% full before reboot, 96% full after reboot). This is likely because 5% or so is reserved for root. Anyway, the most recent time it didn't come back alive...

Gah, bricked again
I was "participating" in the "Bug day", when someone suggested installing gettext to look at translations. I installed this, but got up to 99% full. I then did an `apt-get clean` to empty the cache and this dropped me to 98% full. I've often booted gnulinux boxes with 99% (or even 100%) full, so I figured 98% was fine. I wanted to reboot because often when you reboot the N900, you get space freed, due to the icon cache being liberated. Anyway, on reboot, I got a brick exactly as described above with the second dot more lit than the others (which I have seen reported by others):

* (*) * * *

This time I have my handy kernel with a console, so I can actually see WTF is going on. The images here show some details. In sum, things booted up and the root filesystem check went fine. Then it got an error right after "Freeing Init memory 152K" like this:

getbootstate: Unexpected reset count 50 exceeds maximum (51) getbootstate: Entering state 'MALF'. getbootstate: Houston, we have a problem, powering off...

The /sbin/getbootstate program is in the package "getbootstate". But look at this and hold back the tears:

[sbox-FREMANTLE_ARMEL: ~/getbootstate] > apt-get source getbootstate Reading package lists... Done Building dependency tree... Done E: Unable to find a source package for getbootstate

The getbootstate package appears to be closed source. :( That pretty much ends the debugging and my bug day. Gah.

Flashing N900 with 0xFFFF
Many parts of the N900 are Free Software, but lamentably, many parts are still closed proprietary shit. Nokia's maemo_flasher program is an example of a closed application that Nokia makes for use with the N900. I understand why some parts of their suite are still closed (e.g. pre-ofono GSM stack), but why the flasher has to be closed I have no idea. Gar.

Thankfully, there is The 0pen Free Fiasco Firmware Flasher, which is designed for flashing Nokia tablets and is Free Software (GPLv3). Unfortunately, 0xFFFF doesn't work with the N900. There is some progress to support the device. You can grab the most recent code from the mercurial repository thusly: hg clone http://hg.youterm.com/0xFFFF

I sent the author of 0xFFFF the output of my crash. Hopefully it will soon be a usable tool for flashing the N900. I built RPMs for Fedora 12 x86_64 running the latest mercurial code--the ones in the Fedora repo aren't even the lastest tarball release (0.3.9 vs. 0.4.0).

0xFFFF for Fedora

 * NOTE: recently I checked out the code via Mercurial and saw that the 0xFFFF developer has added much more N900 specific code, but I haven't tried it yet.


 * UPDATE: I have built the latest and greatest code of 0xFFFF from today and made a Fedora 12 package. You can grab it here:

Binary:
 * 0xFFFF-0.4.0-0jebba.fc12.x86_64.rpm

Source:
 * 0xFFFF-0.4.0-0jebba.fc12.src.rpm


 * The 0xFFFF GUI uses gtkamlc. This is not packaged in Fedora. I built it, but compiling the GUI is still barfing.

Flashing with Nokia's Proprietary maemo_flasher
I now have ONE non-free program installed on my computer :(   It's the only way I know how to debrick the phone.

See also: Updating tablet firmware on this wiki.

yum -y install glibc.i686 libusb.i686 ./flasher-3.5 -F ~/devel/maemo/FLASH/RX-51_2009SE_1.2009.42-11_PR_COMBINED_MR0_ARM.bin -f -R
 * To get the most recent image from Nokia, go here: http://tablets-dev.nokia.com/nokia_N900.php
 * Enter product ID inside the phone (without "/"s)
 * Grab RX-51_2009SE_1.2009.42-11_PR_COMBINED_MR0_ARM.bin or whatever is current.
 * To get the proprietary stinking pile of poo, go here: http://tablets-dev.nokia.com/maemo-dev-env-downloads.php
 * Grab maemo_flasher-3.5_2.5.2.2.tar.gz or most recent.
 * In Fedora 12 x86_64 I had to install some i686 libraries since my system is 64-bit. So:
 * Untar the files....
 * Power off phone and unplug USB.
 * Hold down "u" on N900 keyboard and plug in USB cable between computer and N900. A USB icon will appear in the upper right corner--you can let go of "u" on the keyboard at this point.
 * Run this as root:
 * Done.

Info from flasher
sudo ./flasher-3.5 --query-rd-mode flasher v2.5.2 (Oct 21 2009) USB device found found at bus 002, device address 008. Found device RX-51, hardware revision 2101 NOLO version 1.4.13 Version of 'sw-release': RX-51_2009SE_1.2009.42-11_PR_MR0 The device is in production mode

Unpacking flash image
$ mkdir RX-51_2009SE_1.2009.42-11_PR_COMBINED_MR0_ARM-UNPACKED $ cd RX-51_2009SE_1.2009.42-11_PR_COMBINED_MR0_ARM-UNPACKED/ $ sudo flasher-3.5 -u -F ../RX-51_2009SE_1.2009.42-11_PR_COMBINED_MR0_ARM.bin

=Setup= Now that the device is debricked, I can use the thing again and "all" my data is there, but the repository setup is back to default and the applications I want are gone, amongst other things. To re-setup:

ssh server & keys
ssh root@burger ssh localhost scp -p ~/.ssh/id_rsa.pub root@burger:.ssh/authorized_keys ssh root@burger vi /etc/passwd user:!: to user:*: passwd user su - user rm .ssh/known_hosts ssh localhost exit exit ssh user@burger
 * Enable Extras repository: tap, tap, tap...
 * Install openssh client/server package
 * Install rootsh package
 * Set up keys and such for easy access (my device hostname is burger):
 * On laptop, ssh into the sucker:
 * As root on N900, ssh to localhost as a quick/dirty way to setup /root/.ssh:
 * On laptop, copy over ssh key and log back in:
 * To allow ssh access for user "user", the passwd file needs to be edited.
 * Change
 * Set a password for user "user" (I couldn't ssh in without doing this, but someone on IRC said it wasn't necessary):
 * Switch user to "user" and blow out the old known_hosts (or at least edit it) to remove the now bogus "localhost" entry:
 * Quick/dirty way to set up /home/user/.ssh:
 * Then GTFO:
 * This should work happily

Set up Repositories
deb https://downloads.maemo.nokia.com/fremantle/apps/ ./ deb https://downloads.maemo.nokia.com/fremantle/mr0 ./ deb http://repository.maemo.org/extras/ fremantle free non-free deb http://repository.maemo.org/extras-testing/ fremantle free deb http://repository.maemo.org/extras-devel/ fremantle free deb http://repository.maemo.org fremantle/tools free apt-get update
 * Configure the repositories to set up things I like:
 * 1) vi /etc/apt/sources.list.d/hildon-application-manager.list

Apparently the above gets blown out if you run the hildon application manager, so the repos need to be added via tap tap tap.

Configuration
Here's some configuration settings that got lost on reflash. I'm not sure where they are stored, so they need to be re-setup via tap tap tap. Note: if you do a backup on the device you may be able to then run restore which refreshes this, making the below unnecessary; untested.

The below are mostly stored in gconf under /system/osso/dsm/display, I believe these should be restored as per the back-up/restore application. - codeMonkey

=Kernel= Stock kernel: uname -a Linux Nokia-N900-42-11 2.6.28-omap1 #1 PREEMPT Wed Oct 28 15:32:55 EET 2009 armv7l unknown

kernel, kernel-modules, kernel-flasher: 2.6.28-20094102.3+0m5

Custom Kernel Modules
I have built a pile of kernel modules which should work with the stock N900 kernel. See here:

http://www.freemoe.org/users/jebba/kernel/modules/

Installing my custom kernel
Linux Nokia-N900-42-11 2.6.28-omap1-jebba5 #1 PREEMPT Mon Dec 14 00:54:55 MST 2009 armv7l unknown

I have built custom kernel packages closely based on the standard kernel that ships with the N900. Differences:


 * FRAMEBUFFER_CONSOLE=y - This fantastic option means you can see console when the kernel boots up, so you see all the text you usually see when booting up a Linux kernel.

zcat /proc/config.gz
 * IKCONFIG, IKCONFIG_PROC=y - The kernel configuration is available in /proc. To grab it:


 * CONFIG_LOGO=y, CONFIG_LOGO_LINUX_CLUT224=y - Tux, the Linux penguin, at boot! :)


 * The kernel name is 2.6.28-omap1-jebba5 so as to not confuse it with the stock kernel.

You can install this kernel via my repo with apt-get (untested), or manually, which is recommended for now. Procedure (assuming you are running the kernel that ships with the device):

cp -a /lib/modules/2.6.28-omap1 /lib/modules/2.6.28-omap1.orig
 * Make a backup of your current kernel's modules. That way if you want to revert, you can flash it via USB cable and the modules will be there. (You can also revert via dpkg, but this is just in case of "emergencies").

wget \ http://www.freemoe.org/users/jebba/dists/unstable/main/binary-armel/kernel_2.6.28-20094102.3+0m10_armel.deb \ http://www.freemoe.org/users/jebba/dists/unstable/main/binary-armel/kernel-modules_2.6.28-20094102.3+0m10_armel.deb \ http://www.freemoe.org/users/jebba/dists/unstable/main/binary-armel/kernel-flasher_2.6.28-20094102.3+0m10_armel.deb
 * Grab my kernels with wget or whatever (check the dir for more recent versions too).

dpkg -i \ kernel_2.6.28-20094102.3+0m10_armel.deb \ kernel-modules_2.6.28-20094102.3+0m10_armel.deb
 * Install the .debs with dpkg. Note the flasher has to be installed last. If you install them with dpkg all at once, dpkg will prioritize the flasher first, so it won't move the kernel into place. Point of no return:

dpkg -i kernel-flasher_2.6.28-20094102.3+0m10_armel.deb
 * Now install the flasher, which will automatically flash when installed:

rm -rf /lib/modules/2.6.28-omap1 cp -a /lib/modules/2.6.28-omap1.orig /lib/modules/2.6.28-omap1
 * Ok, so the kernel is there, but lets move the original stock modules back into place so you can flash the zImage via flasher-3.5 and USB cable should it be necessary. First we need to remove the mostly empty old dir, then copy the backup:

sudo reboot
 * Now just reboot, yee haw!


 * Enjoy. :)

Compile custom kernel
I followed the procedure in the Maemo Kernel Guide, without making changes. This gave me a bootable kernel. :)

 * 1) disable other stuff in apt sources.list
 * 1) flash the thing
 * 1) wow, sure flashes fast, like in 1 second

To unbrick if something goes wrong, unpack the main N900 .bin flash image and flash with the kernel from there. See unpacking flash image section.

 * Enable framebuffer console so bootup messages can be seen.


 * linux-omap mailing list archives

=VNC= VNC allows you to view the screen of the N900 on your laptop so you can do things more easily that having to use the tiny little thing if you are working on it all day.

x11vnc -storepasswd
 * Set up the Extras-testing repository
 * Install x11vnc (I think it's in -testing).
 * Set up a password for VNC on on the N900:
 * Run this script on your laptop (my hostname is burger and my laptop's IP is 10.0.0.3):

ssh -n user@burger \ "x11vnc \       -usepw \        -display :0 \        -desktop burger \        -allow 10.0.0.3 \        -nolookup \        -q \        -bg \        -o /home/user/vnc-log \        "
 * This works fine with tigervnc on Fedora 12.


 * Running x11vnc with "-ssl" does not work--I think the problem there may be with tigervnc as x11vnc starts with it OK.


 * I usually do VNC in an ssh tunnel--I don't know if this would create too much of a load on the N900 or not. Will test.


 * VNC behaves differently whether the keyboard is slid out or not. Basically, you want the keyboard out.

=Backups= Thankfully, pre-bricking, I had made a backup. There are a billion different ways to do this, but one quick way is good old rsync. This script backs up everything except the --excluded directories which are either things I don't want to back up (cities) or things you can't/shouldn't back up (/proc).

rsync \ -avv -ult --progress --stats \ --rsh=ssh \ --exclude /home/user/MyDocs/cities \ --exclude /home/user/MyDocs/.sounds \ --exclude /proc \ --exclude /dev \ --exclude /sys \ --exclude /syspart \ root@burger:/ \ /home/jebba/BACKUPS/burger/
 * 1) !/bin/sh

=Video=

Encoding Video
I had some video which played way too slow on the N900, so I re-encoded with this pile of cruft:

mencoder $1 -oac mp3lame -ovc lavc \ -lavcopts vcodec=mpeg4:mbd=1:vbitrate=300 -vf scale=352:208 \ -ffourcc DIVX -o $1-out.avi Run thusly:
 * 1) !/bin/sh

burger-encode ralf.mov

And it will give you "ralf-out.mov.avi"...Uh, I will have the output file get a reasonable name, of course... Works for now. This does not work on the N900 at the moment because the mencoder in the mplayer package is compiled without mp3lame support. Bah.

See also (where I got above from): Manual_video_encoding.

Ok, here's a far better script than the above that I took and slightly modified to work with gpac instead of mp4creator.

mplayer
Play video from main "good" back camera: mplayer tv:// -tv device=/dev/video0

Play video from front camera (next to screen): mplayer tv:// -tv device=/dev/video1

Note, the front camera looks absolutely terrible like there is far too much gain or something and has a huge band across the right side. I'm hoping this is just a kernel driver issue and it will contain less suck in the future.

More extensive scriptlet: mplayer \ -fs \ -v \ -nosound \ -ao null \ -nojoystick \ -nolirc \ -ontop \ -framedrop \ -stop-xscreensaver \ -nocache \ -noslices \ -vo xv \ -tv device=/dev/video0 \ tv://

The -tv option can take many more options, like:

-tv brightness=50:contrast=50:hue=0:saturation=-0:gain=0:device=/dev/video0

If your camera settings get weird (e.g. like everybody looks like a green monster), just quit mplayer, close the camera and re-open it. The default/stock program will reset it.

=Gripes=
 * Not all Free Software....
 * 256M of NAND is way too little if it is going to be the root filesystem (/). It is way to easy to fill up. I see that they need to do this for reflashing, but since on reflash all the applications in /opt get lost anyway, what good does it do to have them there? Seems they could have mounted /usr on the 32G, or even better just put /boot on NAND and in that case NAND could even be smaller. Seems very dumb to have 32G+ of space on the device, yet still fill up the rootfs! The vast majority of users are going to have no clue how to repartition (which I will do here shortly) and aren't going to be able to install many applications, which should be a great strength of this device since it can multitask so well and the repositories are going to blossom
 * 4 rows of keys would have been a lifesaver.
 * No | (pipe) or tab key
 * The camera doesn't autofocus, or at least not when you need it to.
 * When charging the phone and talking on it, the power cable is sticking out the top, not the bottom.
 * No dictionary/translation program (!)
 * Docs, info, contacts, etc. are spewed all over the place. For instance, try to find out info about Canola. Some on this wiki, some in garage, some at their site, etc. Where does one file a bug? I've been told to ignore garage and do most at *.maemo.org, but then they should ditch those parts at garage to make things cleaner.
 * SDK pretty much assumes you are running 32-bit Debian or Ubuntu. It's not really cooperating nicely in a Debian Lenny install inside qemu.

=Bugs=

Broken

 * no makedev


 * Alarms not getting backed up with settings.

ln -s /etc/opt /opt/etc
 * Per FSH:


 * After reflash, extra apps are still in /opt, but are "missing" since the symlinks from /usr/bin are gone.
 * More steps needed - which exact apps, did you restore from Backup? --andre


 * Saving preferences in xchat crashes.
 * I can confirm this, but I don't know if the Maemo port of xchat has a separate bugtracker in garage.maemo.org  --andre

`rm -rf ~/.cache/midori ; rm -rf ~/.config/midori`       Start midori. Go to some website. Click "Tools". Click "Clear Private Data". Check "Clear private data when quitting Midori" (but DON'T click "Clear private data" button). Tap blurry part at top to close private data window. Exit Midori. `ls -R ~/.cache/midori/web` and see the .pngs or whatever.
 * "Clear private data on exit" in Midori doesn't actually clear ~/.cache/midori/web (!). I spoke to packager (kalikiana) on IRC and he said he would look into it.


 * `less`, `vim` etc. don't see to like $TERM=rxvt-unicode. Using $TERM=xterm-color works fine. Probably not worth filing a bug...
 * vi is available via default, but not vim. Feel free to file a bug report with exact steps. --andre


 * lcuk: package liqcontrolpanel's summary is "short description". Package should be removed entirely.


 * Image viewer: 1) rotate image 2) view thumbnail. Image doesn't get rotated in thumbnail in *some* cases.


 * Maps viewer (OVI): The program is running ok in Spanish, but map data is in English (e.g. "South Pacific Ocean" "South America"). I first ran the program in English, but have subsequently set the system to Spanish.

RFEs

 * Alarm clock should show current time, not time alarm was set for, or when you hit snooze, you can't see current time (and think it is alarm time!).


 * Package manager can only install one package at a time (in contrast to how synaptic does it, for example).
 * https://bugs.maemo.org/show_bug.cgi?id=601 . Feel free to vote. --andre


 * In package manager you have to keep scrolling down to the package you want. You can't just hit "r" for example and have it scroll to "r" in the list of packages. This is actually pervasive throughout Maemo 5. It seems to only really do this in Contacts app.
 * https://bugs.maemo.org/show_bug.cgi?id=5388 . Feel free to vote. --andre


 * It totally sucks that if someone steals your phone, they pretty much own you. At least /home/user/MyDocs should be encrypted. Ideally this would be done with LUKS and decrypt at boot with a password. Perhaps encryptfs
 * https://bugs.maemo.org/show_bug.cgi?id=6030 is related for Mail storage - feel free to file a new enhancement request --andre


 * In Contacts app, it always shows a SMS button for phone numbers, even if they are landlines.
 * https://bugs.maemo.org/show_bug.cgi?id=6375 - probably WONTFIX for convenience reasons --andre


 * Need a #maemo-devel channel too, as #maemo is noisy...


 * xchat is totally not tweaked for maemo, such as scrolling...

echo "ao = pulse" > ~/.mplayer/config
 * mplayer should use pulsebarfaudio by default, not alsa:


 * Media Player doesn't thumbnail videos after they are taken with the N900 camera/video app. It didn't after closing and re-opening app, but I see they are now thumbnailed (post flashing). Anyway, it should do them "immediately".


 * Lots of internationalization packages are taking up space needlessly. But if, for example, Swedish Calendar support is removed, it wants to remove the whole calendar. The i10n packages should be removable without removing the whole app.


 * OGG support out-of-the-box. I mean, c'mon now...
 * Political reasons - see https://bugs.maemo.org/show_bug.cgi?id=176 --andre


 * App Manager should include $LICENSE in Description.
 * Worth an enhancement request, explaining why you want this --andre


 * qik.com doesn't work with gnash (I mailed them and they mailed back saying, uh, ya, sorry).


 * Continual autofocus on camera (apparently hardware limitation??)
 * Sounds like https://bugs.maemo.org/show_bug.cgi?id=5688 ? Fixed after 42-11 release. --andre

Bugs of Note
Here's a few bugs of interest to me. Please vote for them. :)

No Source Code

 * Please release source code to getbootstate
 * Provide source for libspeex, libspeexdsp

Builder

 * Publishing packages to garage.maemo.org oftens results in "lost connection" and "permission denied" from scp


 * Would be great if it would be possible to see build log of in-progress build


 * We need servers

Argentina Time Zone

 * Buenos Aires, Argentina time off by 1 hour
 * Inital setup time zone: America Latina only lists cities in Mexico

Calendar/Tasks

 * RFE: Show calendar when selecting dates in Tasks/Calendar
 * Provide bi-daily/weekly/monthly recurrences
 * Add option to select multiple days on weekly repeating events.
 * Add relative day option for monthly repeating events (e.g. "1st Monday of month")
 * Day picker shows no daynames - hard to enter recurrence for e.g. 5 days only

Chat & Call & SMS

 * Zoom in/out in IM chat does not reflow contents ("Carolina's bug")
 * Google Talk Video Chat crash & lack of interoperability

Contacts

 * Contacts: Provide "Fax" field(s)
 * Edit/Rename field names or being able to add remarks

Canola

 * Canola last.fm plugin doesn't allow you to enter username/password

Desktop

 * Background image does not show correct rotation

Mailing Lists

 * maemo-announce should be used or shut down

diff/busybox

 * missing diff utility (required by the GNU Coding Standards)

wiki

 * clicking on wiki username *edits* their page instead of viewing it

lsb-core

 * No getopts, called by init-functions (lsb-core) - breaks `/etc/init.d/asterisk start` (asterisk 1.6)

ringtones

 * Assign a ring tone and ring volume on a per-contact level

=My Packages= These are packages I have built and are available in the maemo repository, packages I've built and are in my repository or packages I'd like to see built.

Burgerspace

 * Fantastic. Heh.
 * Workz.
 * maemo packages page
 * Talk discussion thread
 * Bugzilla
 * Built deps libflatzebra and libflatzebra-dev
 * Is aligned left, not center.
 * Press spacebar to begin.
 * ctrl key for salt.
 * Oli wants to throw salt with Z instead--update .desktop
 * First package I figured out the Maemo way for desktop/installer icons and .desktop file for menus. Now that I see all that, this gonna be ez.
 * gtk icon cache script in postinst.
 * get some better larger icons.
 * Need to get fullscreen mode, as too much is cropped.
 * Waiting for bugzilla Product.
 * Many N900 keyboards don't have up and down arrows without holding Fn! This seems like a huge FAIL to me, but need to work around it.

Asterisk
I have asterisk packages in extras-testing.

Connected to Asterisk 1.6.2.0-3 currently running on Nokia-N900-42-11 (pid = 1692)

Asterisk Packages in Maemo extras-testing

 * asterisk
 * asterisk-config
 * asterisk-dbg
 * asterisk-dev
 * asterisk-doc
 * asterisk-sounds-main

Asterisk Bugzilla

 * asterisk bugzilla

Misc

 * BLASTERISK - fantastico.

diffmo!
ok, out of sheer frustration with missing diff utility (required by the GNU Coding Standards) I have packaged up "diffmo", which is diff, diff3, sdiff, and cmp, but renamed to diffmo, diff3mo, sdiffmo, and cmpmo. :)


 * maemo packages page
 * diffmo thread on talk
 * Bugzilla


 * colordiff - would be nice too. I've built it, but it requires diff. May patch it up so it uses diffmo.

Packages in My Repository
I have set up a package repository. To use it you need to add my repo. In the application manager, add it thusly (I'm translating from Spanish, so the words may be slightly different.

jebba http://www.freemoe.org/users/jebba unstable main
 * Catalog name:
 * Web address:
 * Distribution
 * Components

Packages TODO
Package these or get someone to do it.

Dictionary / Translation
I'm really surprised there aren't a dozen of these.


 * fantasdic - dictionary


 * Babiloo - offline dictionary

Wikipedia
I have done an offline wikipedia reader for FREEEEE in the past, but it was only 2000 articles (though with images). Still way small.


 * evopedia looks rad - Gah, uses squashfs which isn't in the n900 kernel (no suprise there), but also isn't in the 2.6.28 kernel. Which would mean patching it in to a kernel that has branched quite a ways from mainline. Which means pain. :(

Misc

 * git - Poked at this for a bit based on git in Debian Sid and updated to the latest release, but they have so much other stuff going on in there, I'm just gonna start from scratch. It compiles and runs, but getting it all into a clean .deb is a mess right now. Also fails tests because there's no `expect` in repos yet.


 * some video conferencing app (telepathy-gabble), jingle etc.


 * tangogps - "an easy to use, fast and lightweight mapping application for use with or without GPS."


 * Take a look at the various OpenMoko (OpenSnot) applications


 * boa - lightweight webserver (cute). Using lighttpd, which seems to fit the bill already tho.


 * lshw - wants PCI stuff, so maybe won't work very well anyway. It doesn't show too much on my Sharp Netwalker.

New Group sbox
In the terminals where you will be running commands you need to run this to show up in the sbox group. Any subsequent times you log out and in you don't need to run it again (in other words, you just have to run this when you first set things up): newgrp sbox

Start Scratchbox & Xephyr & Login
After installation scratchbox is "booted" up. Subsequently (e.g. after a reboot of your laptop) you will need to start it thusly: sudo ~/devel/maemo/scratchbox/sbin/sbox_ctl start

Get Xephyr going, which is the X server. Note the Fedora 12 version doesn't have the "-kb" optioned mentioned in other docs. Xephyr :2 -host-cursor -screen 800x480x16 -dpi 96 -ac

Log in to Scratchbox: ~/devel/maemo/scratchbox/login

This should give you a prompt like this: [sbox-FREMANTLE_X86: ~] >

Then to launch the emulated GUI, run this at the above prompt: af-sb-init.sh start

Then you should have the emulator up and running! :)

Frequently Used Commands
Build binary package: cd foo-1.2.3 dpkg-buildpackage -rfakeroot -b -uc

Build source package: cd foo-1.2.3 dpkg-buildpackage -rfakeroot

Switch to build for ARM: sb-conf select FREMANTLE_ARMEL

Switch to build for x86: sb-conf select FREMANTLE_X86

Kill off things running if it won't let you switch between ARM/x86: sb-conf killall

Grab and start building a source package: apt-get -b source foo

File that describes package being built: vim foo-1.2.3/debian/control

File that has build rules (e.g. where ./configure is): vim foo-1.2.3/debian/rules

File that lists patches to be used: vim foo-1.2.3/debian/patches/series

Source Repositories
One of the "easiest" ways to get things built is to just check to see if it is in any of the Debian repositories and just pillage it from there. Grabbing it from an "old" repository and building it will be easiest because the dependencies are more likely to be the same. Grabbing it from the latest and greatest repository means you will get the most recent version of the package, but will probably have to go through and sort out more dependencies.

Note, you (or I) probably don't want to add the binary repositories to your build environment or you may cause some total chaos in your system. In this case, I am only adding the source repositories.

These are the source repos I added to /etc/apt/sources.list. Note that you have to do this within both architectures (x86/ARM) as they don't share the same sources.list.

 * 3) deb-src http://ftp.ccc.uba.ar/pub/linux/debian/debian/ sid main contrib

Some of the same repos above are listed twice, just to help me keep straight all of Debian's releases. For example "sid" and "unstable" are the same thing. Explanation:


 * Etch - This is what the SDK is based on. It was released in 2007. Version 4.0. ("oldstable").


 * Etch Backports - These are packages which aren't in Etch, or at least not updated to the latest and greatest in Etch, but people "outside" of the Debian project maintain more recent packages. For example, they may have a more recent version of a web browser when Debian's Etch just backports patches to an ancient version.


 * Lenny - This is the "stable" version of Debian. Version 5.0. Released February 2009.


 * Squeeze - This is the "testing" version of Debian and when it is fully done will be the "stable" release and will be version 6.0.


 * Sid - This version will never be stable nor "released" and is always on the bleeding edge. The latest, most recent packages are in this repository. This is like "rawhide" in Fedora and -current in OpenBSD.

maemo-optify
ANOTHER NOTE: I'm not using maemo-optify anymore since VDVsx said it wasn't the real proper way... Now just doing --prefix=/opt and such...

QUICK NOTE (XXX FIX):

From: Marius Vollmer  Jeff Moe  writes: > I installed the maemo-optify 0.2 package from extras-devel but it is missing > the maemo-optify-buildpackage script. I see it in git. Ahh, right. The maemo-optify-buildpackage script is not used any longer. I have removed it from Git to reduce the confusion. The real dpkg-buildpackage in the SDK has been modified directly to call maemo-optify.

Tools to make using /opt convenient for Debian packages. git clone git://gitorious.org/maemo-af/maemo-optify.git
 * maemo-optify README

Maemo-optify is available in the repos and you can apt-get it from within scratchbox, but the .deb is missing the maemo-optify-buildpackage script. I emailed the author to let him know. In the interim, grab it from git, and: cp -p maemo-optify-buildpackage /usr/local/bin

To use it is super-simple, and worked for me without hassle with asterisk: echo auto > asterisk-1.6.1.11/debian/optify maemo-optify-buildpackage -rfakeroot -b -uc maemo-optify-buildpackage -rfakeroot -S

Uh, I also want files of all sizes to be moved to /opt, not just ones above 2048 bytes. Asterisk has 600k of files still, since it has lots of sound files smaller than 2k. There is a forthcoming option to define this in debian/optify, but that feature isn't in place yet. So in the interim remove the maemo-optify packages (from both X86 and ARM), and use this "patch":

--- maemo-optify/maemo-optify	2009-12-04 21:30:51.770927951 -0300 +++ /usr/local/bin/maemo-optify	2009-12-06 17:39:22.000017316 -0300 @@ -127,7 +127,7 @@        dbg "link, nope\n"; } elsif (!

Maemian
Lint tool for Maemo packages. Gotta do no ssl verify to clone things from git.maemo.org

GIT_SSL_NO_VERIFY=0 git clone https://git.maemo.org/projects/maemian

Configure Scratchbox environment
Within scratchbox: echo ":syntax on" > ~/.vimrc echo ":set paste" >> ~/.vimrc echo ":set nobackup" >> ~/.vimrc echo "export TERM=xterm-color" >> ~/.bashrc

I still feel like a total noob sometimes in that I don't even know how to get my fkn Home/End keys to work in the scratchbox. heh. Hint anyone? :)

SDK Errors
If you get this: ERROR: Scratchbox is not properly set up!

Run this: sudo /scratchbox/sbin/sbox_ctl start

SDK+
This is the "alternative" SDK based on Scratchbox 2. I don't have it working yet on Fedora 12 x86_64. It complains and says it just works on i386 ARCH.

Maemo SDK+ - Alternative SDK for Maemo based on Scratchbox 2.

http://maemo-sdk.garage.maemo.org/maemo-sdk-installer.py chmod +x maemo-sdk-installer.py sudo ./maemo-sdk-installer.py install -g

Hmm. Well, this is crashing and burning on x86_64:

$ sudo ./maemo-sdk-installer.py install -g Operating system's machine or word size (x86_64) is not supported. These are supported: ['i386', 'i686'] System check failed!

Things possibly needed: yum -y install redhat-lsb

debootstrap
Perhaps I should install this sucker in an etch chroot...

yum -y install debootstrap debootstrap --arch=i386 etch /home/jebba/devel/etch-i386 http://ftp.ccc.uba.ar/pub/linux/debian/debian/

Free Development Box
I have set up a server for folks to use that don't have access to a /scratchbox, can't set one up, want a faster one, etc. If you would like access to it, drop me a note at moe@blagblagblag.org

Website

 * Free devel box

The website has subdirs for users if they want to share the .debs they make. I have made mine a repository so packages can be grabbed with the Hildon Application Manager or apt-get.

buildrepo
This is my buildrepo script. I think I may change the repository setup so I have fremantle, harmattan, etc. sub-directories. It is not generating .diffs, which would make `apt-get update`s faster, but then again, it's a teeny repo right now so that probably doesn't matter. Tips welcome.

QEMU
The build server is running as a qemu guest. It is launched from the host thusly:

/usr/local/bin/qemu-system-x86_64 \ -drive \ file=/kvm/flauta.qcow2,index=0,if=virtio,cache=writeback,boot=on \ -drive \ file=/kvm/www-freemoe.qcow2,index=1,if=virtio,cache=writeback \ -drive \ file=/kvm/scratchbox1.qcow2,index=2,if=virtio,cache=writeback \ -cpu qemu32 \ -m 2048 \ -vnc :5 \ -daemonize \ -enable-kvm \ -name flauta \ -net nic,vlan=0,model=virtio \ -net user,hostfwd=tcp:63.247.92.155:22-:22,hostfwd=tcp:63.247.92.155:80-:80 \ -smp 8 \ -runas jebba
 * 1) !/bin/sh


 * It is running the "current" QEMU git (d0be2513d5eefb47a83f9a303fe142dd8ef72848).


 * Host kernel is custom 2.6.32.


 * Guest is running Debian Lenny with stock Lenny kernel.


 * The guest is running a custom 2.6.32 kernel now. A good sample .config optimized for qemu would be fantastic. Currently only seeing 883M (before seeing 2G) likely due to turning off 4G/4G which I turned off for speed per QEMU docs. Not sure if lots of memory will speed things up anyway--the filesystem will just get cached on the host.


 * The guest panicked once (when building a kernel.deb for ARM running `dpkg-buildpackage -j8 -rfakeroot -b`...), hence the drive to run a more recent guest kernel.
