Will those scripts work on a Debian amd64 system also?

I am not able to chroot into the mounted SD-card. Here is the output:

Code:

chroot: failed to run command `/tmp/install-chroot-part.sh': Exec format error

EDIT: Either loading binfmt_misc module

Code:

modprobe binfmt_misc

or installing binfmt-support

Code:

apt-get install binfmt-support

on the host did enable a successfull chroot command.

unknown.obvious, I think we need to develop a naming convention to add your kernels support to the script until those get published somewhere more "official"

Can you make the archives unpack to folders with names starting "custom_kernel*", "custom_n900_kernel*" or whatever you like?

UPDATE:
Looks like Tom Gall wanted to make a hardware pack for N900. I'll try to contact him.

Do you prefer a big one with kernel_image, kernel_headers and kernel source or is one kernel_image enough?

Linaro doesn't do much omap3 stuff anymore, hope things work out.

Big one if it's not too complicated for you.

MD5SUM: ce939d2d2a43aa14aecc5528288a47b1 custom_kernel.tar.gz

looks like this:

custom_kernel.tar.gz --> /custom_kernel / --> .deb

Before replacing armel build with armhf build run (added to the script in rev 108)

Code:

dpkg -P linux-image-2.6.37-n900:armel
dpkg -P linux-headers-2.6.37-n900:armel

Explanation:

Code:

# dpkg -i linux-image-2.6.37-n900_6_armhf.deb 
dpkg: error processing linux-image-2.6.37-n900_6_armhf.deb (--install):
 linux-image-2.6.37-n900: 6 (Multi-Arch: no) is not co-installable with linux-image-2.6.37-n900:armel 2 (Multi-Arch: no) which is currently installed

# apt-get purge linux-image-2.6.37-n900
Virtual packages like 'linux-image-2.6.37-n900' can't be removed

I have made a video featuring some capabilities of Ubuntu 12.04 running on N900. The video isn't perfect but still more than nothing.

So could you make a post of instructions how to get a working system? There are so many package options and I don't know which are needed to make it work - and I still don't understand what to do in the chroots, so I've just been using the Nemo kernel. I got it to boot as far as the login screen, but I couldn't click anything (although I could move the mouse) and I couldn't type in a password, so it pretty much wasn't working.

Also, if it would be possible for the script to create images as well as writing to a SD card - my only computer with a SD card reader is quite slow (it takes about 6 hours to run your script), so I'd prefer to create the image on a faster computer and then just use my netbook to write the image to the card.

Please check the first post, it was updated recently. Also, update the script with bzr pull. I've used Ubuntu Core with unoobi's kernel, lubuntu-desktop and lxdm packages IIRC.
Looks like inability to login is lightdm's fault, try installing lxdm or gdm instead by using sudo bash just_chroot.sh

On installation into the file:
I've added an option to use file or partition instead of the device node.
But it will create only one ext partition with the root filesystem this way and right now number three is hardcoded in the boot.scr so you either have to recreate the 1:fat, 2:swap, 3:root scheme and put the image on the third one or change the boor.scr file.

UPDATE:
Alternatively, you can change the TARGET_ROOT_PARTITION_NUMBER variable on the beginning of the install.sh file, MMCPART in the install-chroot-part.sh and maybe the line with ITEM_DEVICE.

UPDATE 2:
use fallocate -l #G filename to create the file.
