Hi, I tried openSUSE-Tumbleweed-ARM-XFCE-chromebook.armv7l-2017.07.22-Build1.1 recently, but it just beeps and kicks me back to the boot screen immediately. No messages on screen, partition resizing, etc. Any hints? Some cgpt magic I could try from ChromeOS perhaps?

You can try installing upstream u-boot following the chainload steps deteailed in several places on the interwebs - eg here http://chrodyssey.blogspot.cz/2015/04/the-bootloader-chained.html The current u-boot supports display on Snow but the EFI GOP emulation (which the Tumbleweed image would use if it booted) is broken. It probably does not boot because the loader is missing or not marked as bootable or you did not enable USB boot on the chromebook. The developer mode on current versions of ChromeOS has more features than it used to but is also more flaky - it seems services tend to stop working randomly and currently I Cannot boot at all after the devmode installation fell apart.

thanks to both of you (Michal and Misha) for your answers, nice to hear that you didn't give up on Snow, even since it is no longer available for purchase. I played around a little with the broken image, but failed to recompile u-boot as described in the above link - need to dig into this. I switched (temporarily, i hope) to archlinuxARM [1], which works fine (all HW incl. 2d acceleration), but it is uncomfortable for me, since i've never used archlinux before. Kali (Debian-based) works, too, but has no 2d acceleration. Both appear to use the ChromeOS-kernel. I don't use ChromeOS, but keep it up-to-date via guest mode - maybe a not-so-good idea afterwards...

It seems that Build2.4 has video output broken. I guess this is due to new 4.14.0 kernel? Unfortunately, I do not have any serial access on my chromebook. Could you have a look, since it seems you have serial on your chromebook. Or anyone else? Guillaume

You can try installing upstream u-boot following the chainload steps deteailed in several places on the interwebs - eg here http://chrodyssey.blogspot.cz/2015/04/the-bootloader-chained.html

The current u-boot supports display on Snow but the EFI GOP emulation (which the Tumbleweed image would use if it booted) is broken.

It probably does not boot because the loader is missing or not marked as bootable or you did not enable USB boot on the chromebook.

The developer mode on current versions of ChromeOS has more features than it used to but is also more flaky - it seems services tend to stop working randomly and currently I Cannot boot at all after the devmode installation fell apart.

i tried openSUSE-Tumbleweed-ARM-JeOS-chromebook.armv7l-2017.10.02-Build1.1 today and still no luck. Did you dig into this already? I'm not skilled enough to be helpful in this stage, i'm afraid...

Guillaume fixed chromebook snow images you can try current TW build http://download.opensuse.org/repositories/devel:/ARM:/Factory:/Contrib:/Chro... It boots fine here, i only expirienced hard freeze on first boot which chanhes partition setup, here is fault output to serial uart http://paste.opensuse.org/98361543 If it wont reboot for too long on first boot you probably also caught this fault just reboot by power key, second boot is fine.

It seems that Build2.4 has video output broken. I guess this is due to new 4.14.0 kernel? Unfortunately, I do not have any serial access on my chromebook. Could you have a look, since it seems you have serial on your chromebook. Or anyone else?

I tried 2017.11.17-Build2.4 today: It boots (yay!) and resizes the file system. After "Starting the kernel" the screen goes and stays black. So, yes, video output broken seems likely. I will try again as soon as a new build is available. Thank you very much, both of you. Best regards, --Daniel.

Hi,

I tried openSUSE-Tumbleweed-ARM-XFCE-chromebook.armv7l-2017.07.22-Build1.1 recently, but it just beeps and kicks me back to the boot screen immediately. No messages on screen, partition resizing, etc.

Last version i tested was openSUSE-Tumbleweed-ARM-JeOS-chromebook.armv7l-2017.06.10-Build2.10.raw.xz, it worked fine except outdated armsoc driver. But after that i updated vboot package to newer version to play with newer chromebooks, maybe it is broken with snow, i will try newer builds to find out.

...

Any hints? Some cgpt magic I could try from ChromeOS perhaps?

You can try to boot old openSUSE 13.1 version to find out that your sdcard or usb flash is ok first, if yes try to rebuild chaniloading partition.
