Carrying on from my last post, with advice from Alexander Graf on #opensuse-arm, I was able to put together a reasonable looking pre-built openSUSE 12.2 image for the Gumstix Overo. This is currently in home:tserong:branches:openSUSE:12.2:ARM on OBS, and will presumably remain there until next time I’m able to hack on this.
The two things that needed doing were:
- A u-boot-omap3overo package, which is u-boot-omap4panda with an extra spec file and a small patch to add some load addresses and make the default environment boot off ext2 instead of FAT:

- A JeOS-overo image, which is just another KIWI file for the base ARM JeOS image with a few tweaks to make it use my u-boot-omap3 overo package and the right kernel. To give an idea, the diff between JeOS-panda.kiwi and JeOS-overo.kiwi is:

I couldn’t specify bootkernel="omap3overo" because that profile doesn’t exist in kiwi. Leaving this out, combined with the reference to my repository and <package name="kernel-omap2plus" bootinclude="true"/> miraculously gave me the right kernel.
To actually get it running, first the image went onto a MicroSD card:
# xzcat openSUSE-12.2-ARM-overo.armv7l-1.12.1-Build1.17.3.raw.xz | dd bs=4M of=/dev/mmcblk0 # sync
Then the card went into the Overo, power was applied and it immediately failed to boot, because X-Loader couldn’t read the boot sector on the MicroSD.

But, the old u-boot in my Overo’s NAND is sufficiently advanced that it can read from an ext2 partition, so I was able to do this:

Anyway, it did boot successfully after that and I was able to log in, poke around a bit, and reboot. During reboot I got a couple of kernel oopses, same as (or presumably the same as) with my previous manually constructed image:

So ignoring that for the moment, on the second boot (after KIWI had done its magic to finish setting up the MMC card), my new u-boot loaded. Note though that it’s still using the old environment variables at this point (which try to “fatload” in “loadbootscript”, which isn’t going to work), so that needed resetting:

Fourth time’s the charm. Straight into loading the kernel and initrd without any manual intervention required:

This is the Lime-JeOS 12.2 SuSE Linux System.
To upgrade your system call:
zypper refresh
zypper install -t product openSUSE-12.2
Have a lot of fun...

So I call that reasonable success. At least now I have a documented point to start from next time. Oh, and that little red LED? It’s a heartbeat indicator. So long as it’s blinking, the kernel hasn’t crashed.
