Ok, uboot-n900-tools in the repo. Changed behavior presented in here for the interested. For the uninterested:

Add to fstab, adjust if necessary:
Code:
ubi0:rootfs /mnt/maemo ubifs defaults,noatime,bulk_read,no_chk_data_crc 0 0
/dev/mmcblk1p2 /mnt/maemo/home ext3 defaults,noatime 0 0
/dev/mmcblk1p1 /mnt/maemo/home/user/MyDocs vfat defaults,noatime,uid=1000,gid=100,umask=022 0 0
As root, emmc and nand partitions unmounted:
Code:
echo "options ubi mtd=rootfs" > /etc/modprobe.d/ubi.conf
echo "softdep ubi pre: omap2" >> /etc/modprobe.d/ubi.conf
mkdir /mnt/maemo
mount -a
ln -s /mnt/maemo/etc/bootmenu.d /etc/bootmenu.d
ln -s /mnt/maemo/etc/default/bootmenu.item /etc/default/bootmenu.item
I tried to reproduce all the stupid user errors I've heard happening with u-boot, so far it's been working fine and safe, for me. I'm dead tired, so don't copypaste, I didn't :P

EDIT:
Oh well, setting up everything in fstab drops to emergency mode, module dependencies have to be defined manually, I'll get back to this asap.

EDIT2:
Corrected and updated, update your fstab and do trough the steps again. Let me know if some issues arise.

Hello everyone

@Skry
Thanks for the hard work

It's really amazing to have arch linux on N900

@Skry
have a question please
I did the following
1- formated mmcblk0p5 (logical) to ext4
2- untar then sync your unofficial image to the above partition.
3- installed U-boot (the version that supports booting kernel 3.x)
4- added boot menu item in /etc/bootmenu.d/30-Arch.item

Code:
ITEM_NAME="Arch Linux ARM"
ITEM_KERNEL="/boot/uImage"
ITEM_DEVICE="${EXT_CARD}p1"
ITEM_FSTYPE="ext4"
ITEM_OMAPATAG="1"
ITEM_CMDLINE="root=/dev/mmcblk0p5 rootwait init=/bin /systemd omapfb.vram=0:3M,1:3M,2:3M quiet"
5- then u-boot-update*

But when I try to boot to Arch I get "Kernel Panic"
What am I doing wrong ?

actually I don't know how to deal with U-boot
I didn't understand the part about U-boot
and where do I have to put the "uImage" and how to boot correctly
Please guide me, what should I do to successfully boot Arch

Thanks

EDIT: forgot to say that I've manged to chroot to /dev/mmcblk0p5 successfully

You're welcome, it is amazing indeed.

Change
Code:
${EXT_CARD}p1 -> ${EXT_CARD}p5
and
Code:
init=/bin /systemd -> init=/bin/systemd
and it should boot.

You don't need to copy uImage anywhere if you configure uboot to look under /boot for it, like you've already done. Good luck.

I changed to ${EXT_CARD}p5
but init=/bin/systemd was right, (writing mistake )


I did the fixes you told me to do, But when you boot to Arch
U-boot says
Code:
mmc0 is current device 
** Bad partition 5 **
after this when I run
Code:
run emmcboot
I have a Kernel Panic
Code:
Kernel Panic - not syncing: VFS: Unable to mount rootfs on unknown-block(179,5)
(this is one of the lines)

btw : I tried multiple versions of u-boot with no luck
current version is "2012.04-2"
Also tried version "2012.10-rc3-1"

NOTE: when Kernel Panic happens, N900 can't be powered off using power button, you have to remove the battery which is bad
and also chroot worked fine, I tried doing pacman -Suy and it worked

I think I'm missing some part of U-boot boot, but I don't know what is it

Thanks in advance.

EDIT:Also removed boot flag from mmcblk0p5, also didn't work
Also replacing ${EXT_CARD}p5 with ${INT_CARD}p5 didn't help

Thanks in advance.

Uh, since I usually refer to how devices are named in reality, I understood you had everything on uSD-card, sorry. You see, Maemo swaps mmc device numbering around, so, change to ${INT_CARD}p5 and root=/dev/mmcblk1p5

I'm quite interested in trying this, especially seeing as you, Skry, and many others have put in a lot of effort, thanks a lot, since the last time I looked at this project a long time back.

I've got a few questions that hopefully some one can answer in order to clear my confusion up, sorry if I they've been answered elsewhere but I've not been able to find them:

What is the difference between the official rootfs, and the one provided by Skry? Is the unofficial just fine tuned towards the N900?

Once setup, am I free to 'pacman -Syu' once in a while, or are there any packages I must hold off from updating (the kernel especially)?

I've got a lot of free hosting space & bandwidth on my dedi., & free domains if you fancy centralising this and moving away from dropbox/other file hosters.

Great
I get U-boot console this time
but when I run

Code:
run emmcboot
It works


Thank you very much @Skry
Now there is one more Arch user on N900 :-]

I'll try to contribute to this project
keep up the great work.

Yeah, I've spent countless nights with this one, you're welcome. Hopefully you decide to give it a go.

Mine has kernel for N900 and my integration packages included. I also included dialog to make use of the wifi-menu, so one can just simply extract it and boot. No need to play around in chroot unless one wants to.

You're perfectly free to -Syu all you like, no need to hold anything back. Also, everything is optional and split, so you can pick what you want, grab everything or simply do things your way.

Repositories are also split, currently to base which includes only the few essential packages, and to extra where majority of the integration, special tools and modified packages are. There is going to be two more, testing and neon. So, there is no forced dependencies to anything, and no right or wrong way to setup your system, the choice is all yours.

I certainly do fancy doing just that. I've put a lot of personal time into this but unfortunately money is something I can't invest. PM me or query me at IRC and we can discuss this further.

Can you please clarify, is Arch installed all on your microSD card or ?

From your partition info, it seems like it is on your card....but from some comments read, I'm not sure...

Hope to get Arch installed on my 900 soon.....

Thanks.
