N900 Install

Mer installation

Mer Image

The latest release as of this post is 0.17testing4.

# you need an ext3 formated MicroSD card.
mount -o noatime /dev/mmcblk1p1 /media/mmc1/

# go hence
cd /media/mmc1/

wget http://stskeeps.subnetmask.net/mer/0.17testing4/mer-armel-generic-image-v0.17testing4.tar.gz

# Untar it verbally to see the majick.
# Note this will create dirs like ./usr and ./lib etc, so you don't want stuff pre-existing in those dirs.
tar zxvf mer-armel-generic-image-v0.17testing4.tar.gz

# sync and live free!
sync

bootmenu

You need to have getbootstate version 1.0.35+0m5 or greater for this to work.

dpkg -l getbootstate

(As a side note, getbootstate is close software. Please vote for this bug and/or clamour for it to be released as free software.)

discussion on t.m.o

# 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 bootmenu docs.

I put everything on the first and only 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 1)"
ITEM_ID="mer"
ITEM_DEVICE="${EXT_CARD}p1"
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

0.17testing4 fixes for N900

# root does all
sudo gainroot

# mount up the MicroSD
mount -o noatime /dev/mmcblk1p1 /media/mmc1/

# go hence
cd /media/mmc1

# create a missing directory
mkdir mnt/initfs

# load modules to get touch screen working
vim etc/init.d/auto-startx 

# copy over modules from main OS:
cp -a /lib/modules/*  /media/mmc1/lib/modules/
