N900 Install
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...
Mer Image
The latest release as of this post is 0.17testing4.
NOTE: Earlier versions of this "howto" used partition 1. I now have everything on partition 3!!!! Update your scripts as needed!
# you need an ext3 formated MicroSD card. mount -o noatime /dev/mmcblk1p3 /media/mmc3/ # go hence cd /media/mmc3/ wget http://stskeeps.subnetmask.net/mer/0.17testing4/mer-armel-generic-image-v0.17testing4.tar.gz # Untar it verbosely 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
NOTE: Earlier versions of this "howto" used partition 1. I now have everything on partition 3!!!! Update your scripts as needed!
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 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 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
(It should be mentioned how to undo the following aswell)
0.17testing4 fixes for N900
NOTE: Earlier versions of this "howto" used partition 1. I now have everything on partition 3!!!! Update your scripts as needed!
# root does all sudo gainroot # mount up the MicroSD mount -o noatime /dev/mmcblk1p3 /media/mmc3/ # go hence cd /media/mmc3
Missing dir needed at boot
# create a missing directory mkdir mnt/initfs
Need modules from kernel
# copy over modules from main OS: cp -a /lib/modules/* /media/mmc3/lib/modules/
Fix touchscreen
I STILL DON'T HAVE THIS WORKING.
auto-startx
To get the touchscreen working you have to edit this file: /media/mmc3/etc/init.d/auto-startx. Patch it ala:

Note to self: I have a copy of this in /home/user/MyDocs/Mer, so when copying back over be sure to chmod because VFAT loses perms gah:
chmod +x /media/mmc3/etc/init.d/auto-startx
remove synaptics driver
sudo gainroot chroot /media/mmc3 /bin/bash dpkg --remove \ xserver-xorg-input-synaptics \ xserver-xorg-input-all
Add xserver-xorg-input-tslib
sudo gainroot apt-get update apt-get install xserver-xorg-input-tslib
upgrade
Note sure if it's needed, but:
chroot /media/mmc3 /bin/bash apt-get update apt-get upgrade
This got me new updates:
hildon-input-method libclutter-0.8-0 libetpan13 libhildon-im-ui3
The first one sounds helpful.
Set root password
Might as well set one in the chroot. I had X not come up once, but couldn't log in.
sudo gainroot chroot /media/mmc3 /bin/bash passwd
Misc
When you are booted up into Fremantle, it wouldn't hurt to fsck your MicroSD too....
umount /dev/mmcblk1p3 && fsck.ext3 -vvv /dev/mmcblk1p3
Automated install
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:
user ALL = NOPASSWD: ALL

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.
