Hello, Just tried to book chromebook images version 253. Usb wont boot sayin no kernel found, maybe so trick is required?
You need an updated u-boot. ;) I am waiting for 2015.01-rc3 (should be out in 2 or 3 days) to push my changes because there are lots of problem with -rc2. If you want to test now, please use this u-boot (based on a modified GIT version): http://guillaume.gardet.free.fr/openSUSE/u-boot.img Then, copy it to your USB stick with this script (update path to u-boot.img and fix your device: /dev/sdX): http://guillaume.gardet.free.fr/openSUSE/dd_snow.sh SD card booting is not working ATM, so please boot from USB (black USB2 slot, not blue USB3 slot). JeOS is working fine. X11 images are broken (strange display once Xorg is booted, only the cursor is ok.) Guillaume

From SD i can reach u-boot, it said unknow partition for mmc dev 1 and detect capacity is wrong.

If i try to use SD card and USB stick at same time, mainline u-boot start only XHCI hub and wont detect any storage devices here:

Hello, I found that kernel or dtb file in current Chromebook contrib factory image, tested on version 245, have boot problems. After kernel start no signs of activity on stdout or serial console.
If i replace linux.vmx and dtb on lxboot partition and modules on lxroot with same files from 12.3 dist image for chromebook im able to boot and pass installation fine.
Also after installation and reboot, sd card not bootable at all, first partition on sdcard changed type code to 0700 and size to 32mb, probably cgpt script failed to fix it after installation for some reason.
Bundled armsoc x11 driver fail to start because it is for abi 13 not abi 18.
I updated armsoc driver just now from 0.0.1 to 1.1.0. It may help. :)
That does indeed sound pretty broken. I think someone needs to sit down and check which of all those components is already done well enough upstream to drop our hacks.
For example, I think u-boot has upstream snow support now, so we could just use that. The kernel should be ok as well.
Current Factory u-boot-snow (2015.01-rc2) does boot but is not really usable. It seems there is a problem to access SD card. But LCD and keyboard are working fine. :)
I will have a look at it.
With some patches, I am able to use a USB stick (no external SD) with upstream u-boot-snow and Factory kernel-lpae does boot ! On kernel start, you must wait a little bit because at the beginning, there is just a black screen, followed later by a normal screen and a blue YaST Firstboot screen. :)
But the are some problems: * upstream u-boot does not handle external SD card for an unknown reason (internal eMMC is usable). Downstream u-boot has no bootz support. * keyboard does not work under Linux (you must use an USB keyboard). * Second boot is deeply broken. U-Boot is not launched at all because "cgpt" command is applied to /dev/mmcblk0 (internal eMMC) instead of /dev/sda (USB stick) (Kiwi bug?). Once this one manually fixed, u-boot load the kernel and then hang with a black screen. Probably due to missing modules in dracut initrd. (I will submit a JeOS update once tested) * No wifi (at least on 1st boot)
I will send an update (and SR) once tests are passed.
