new_kern is built using vbutil_kernel command. So, you need the vboot package
to be installed:

dd_snow.sh script need also /tmp/newkern is it symlink to u-boot.img
or real new kernel?

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.)

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.
