Great post\Nice post, I enjoyed it a lot.I was pretty lucky to discover your site. It has so much helpful info!  
-
Note, this is still in a *very* rough state. Currently, you can't recharge the battery while using Mer, nor even draw power when plugged in, so developing on it means you have to reboot just to recharge your battery. No phone calls are possible yet. Grabbing binaries of the proprietary crock from Nokia requires rebuilding packages and jumping through hoops. On the positive side, it boots. :)

You can do this without erasing your main install, FYI...

You need to have getbootstate version 1.0.35+0m5 or greater for this to work.
+
-
 
+
-
dpkg -l getbootstate
+
-
 
+
-
(As a side note, [https://bugs.maemo.org/show_bug.cgi?id=7019 getbootstate is closed software]. Please vote for this bug and/or clamour for it to be released as free software.)

# Grab this package:

wget http://www.daimi.au.dk/~cvm/bootmenu_1.6_armel.deb
+
-
+
-
# Be root

-
sudo gainroot
+
-
+
-
# Install bootmenu
+
-
dpkg -i bootmenu_1.6_armel.deb
+
-
 
+
-
Then tappy tap tap the bootmenu install icon and answer yes.
+
-
 
+
-
Now you need to set up Mer in the menu for bootmenu. See also: [[Mer/Documentation/Bootmenu| Mer bootmenu docs]].
+
-
 
+
-
I put everything on the third partition on an ext3 formatted "external" MicroSD card (the one that's right next to the camera).
+
-
 
+
-
# edit/create this file to create a boot menu item for Mer:
+
-
vim /etc/bootmenu.d/mer.ext.item
+
-
+
-
# Make it look justa lika thisa:
+
-
+
-
ITEM_NAME="Mer (external SD, partition 3)"
+
-
ITEM_ID="mer"
+
-
ITEM_DEVICE="${EXT_CARD}p3"
+
-
ITEM_MODULES="mbcache jbd ext3"
+
-
ITEM_FSTYPE="ext3"
+
-
ITEM_FSOPTIONS="noatime,ro"
+
-
 
+
-
 
+
-
(Note: why jbd module needed?)
+
-
 
+
-
Then shutoff the phone and reboot with KEYBOARD SLID OUT, so you get the bootmenu.

==Disable watchdog==
+
-
 
+
-
You have to disable the watchdog with the flasher tool or the system will just shut down on bootup:
+
-
 
+
-
./flasher-3.5 --set-rd-flags=no-omap-wd
+
-
+
-
./flasher-3.5 --set-rd-flags=no-ext-wd
+
-
+
-
./flasher-3.5 --enable-rd-mode
+
-

+

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

When you are booted up into Fremantle, it wouldn't hurt to fsck your MicroSD too....

Ok, here's dodgy scripts to automatically do lots of the above. I set these up because in the process of doing this I corrupted the filesystem on the MicroSD card enough times that I kept having to do this. If you don't understand what these scripts are doing, don't run them. Ah, and I use sudo lots, so you probably want do add this to /etc/sudoers:

=Installing Fremantle Packages=
+
-
Mer is missing some key parts, such as charging from battery and making phone calls. The first is killer, the second is a major drawback... Nokia decided to keep these parts proprietary which makes Mer on the N900 pretty pointless actually. Gar.
+
-
 
+
-
So I thought I would try to install (most begrudgingly) their proprietary Fremantle battery and cell phone applications under Mer. I was able to get the battery applet and some of the hal stuff going, but I don't think it was actually *doing* andything. I then installed the cell phone application, which pretty much screwed up the install.
+
-
 
+
-
So, in sum, the following doesn't work, but is a possible starting point for getting battery charging working under Mer.
+
-
 
+
-
I didn't have access to the original .debs, so I decided to just reconstruct them from the ones already installed under fremantle. It's a bit out there, but this is how I did it:
+
-
 
+
-
# boot into Mer
+
-
+
-
# We'll use dpkg-repack to rebuild the .debs
+
-
apt-get install dpkg-repack
+
-
+
-
# set up nice working space:
+
-
mkdir -p /mnt/fremantle
+
-
+
-
# umount the read/write of the NAND since we crash all the time and run out of battery
+
-
umount /mnt/initfs
+
-
+
-
# Remount it read-only some place nicer
+
-
mount -o ro -t ubifs ubi0:rootfs /mnt/fremantle/
+
-
+
-
# And put /home and the infamous /opt there too
+
-
mount -o ro /dev/mmcblk1p2 /mnt/fremantle/home/
+
-
+
-
# ...and MyDocs under that
+
-
mount -o ro /dev/mmcblk1p1 /mnt/fremantle/home/user/MyDocs/
+
-
+
-
# Set up stupid symlink for the /opt mess
+
-
cd /home
+
-
ln -s /mnt/fremantle/home/opt .
+
-
+
-
# create a nice place to put the .debs we'll create
+
-
mkdir /root/REPACKS
+
-
+
-
# go hence
+
-
cd /root/REPACKS
+
-
+
-
# take a look all those fremantle applications
+
-
dpkg -l --root=/mnt/fremantle/
+
-
+
-
# Repack some random single package
+
-
dpkg-repack --root=/mnt/fremantle/ burgerspace
+
-
+
-
# rebuild the local repo
+
-
cd /root/REPACKS
+
-
dpkg-scanpackages . /dev/null | gzip -9c > Packages.gz
+
-
+
-
# Add this to /etc/apt/sources.list and perhaps comment out all the others
+
-
deb file:///root/REPACKS ./
+
-
+
-
# update from our new local repo
+
-
apt-get update
+
-
+
-
# and see that it works
+
-
apt-cache search burgerspace
+
-
+
-
# if that works, you can do them one at a time, or repack all of the
+
-
# fremantle debs with this:
+
-
for i in `dpkg -l --root=/mnt/fremantle/ |grep ii | cut -f 3 -d " "` ;
+
-
do echo $i
+
-
dpkg-repack --root=/mnt/fremantle/ $i
+
-
done
+
-
+
-
# Then re-run the archiverthinger
+
-
cd /root/REPACKS
+
-
dpkg-scanpackages . /dev/null | gzip -9c > Packages.gz
+
-
+
-
# update
+
-
apt-get update
+
-
+
-
# now install whatever
+
-
apt-get install foo
+
-
+
-
# This will get you a battery applet. It appears in the notification
+
-
# area, but I'm not sure if it is working or not. Perhaps try rebooting
+
-
# after installing it, and don't install other stuff which may pooch it
+
-
apt-get install hald-addon-bme bme-rx-51 status-area-applet-battery
+
-
+
-
# After I installed this, I had a mess
+
-
apt-get install rtcom-call-ui
+
-
 
+
-
Oh, and I guess I should also point out, that all of this needs to be done because nokia is doing something funky with apt-transport-https. I tried rebuilding theirs and using it under Mer, but it barfed on libraries. I tried using the Ubuntu one but that didn't work with the Nokia repos, even after copying over /etc/apt/auth.
+
-
 
+
-
Another way to do this would perhaps be to apt-get mirror the repos, if possible or a --download-only type approach. I didn't have apt-transport-https working so I just did this. Time for bed.
