Tenkawa: CONFIG_DEBUG_LL might help?
<
TheSeven>
at least if you have access to a serial port
<
javier__>
so quite likely the problem is at your side

javier__ I'm sure it is something I'm doing wrong.. just not sure what
<
Tenkawa>
i'll try that defconfig and see if I'm pulling something out
<
Tenkawa>
javier__: thanks for the link
<
Tenkawa>
TheSeven: thanks
<
Tenkawa>
javier__: can that be retrieved with links/lynx?
<
Tenkawa>
I'll be back in tomorrow to work on it some more
<

javier__: hey ya around?
<
javier__>
Tenkawa: yes
<
Tenkawa>
I'm going to try this 4.5-rc kernel build again for this cb1-snow
<
Tenkawa>
what did you say I needed to follow?
<
Tenkawa>
I'm building the exynos_defconfig kernel now

is exynos5250-snow.dtb the one I should be using for the samsung chromebook 1?
<
Tenkawa>
ok its compiled... lets see if it will boot

javier__: ok I think this is going to be easy to fix.. it booted however the screen was solid white
<
Tenkawa>
do you know what I missed by chance?
<
Tenkawa>
I was able to type/interact and it shows up that kernel as last one booted before i rebooted to the old one
<
Tenkawa>
I recall this happening before however dont remember what the fix was
<
Tenkawa>
got something to try... brb

darn.. that experiment didnt work
<
Tenkawa>
still solid white screen
<
Tenkawa>
ooh it even sees my soundcard
<
Tenkawa>
if I can just get it to display
<
Tenkawa>
got another experiment to try
<
Tenkawa>
I just get the feeling its something with the framebuffer/graphics
<
Tenkawa>
I think I'm missing a setting
<
Tenkawa>
ok here goes next experiment

hehe the annoyance of being this close

javier__: does it sound like i'm missing anything super obvious?
<
javier__>
Tenkawa: sorry, I wasn't paying attention to IRC and I'm about to leave
<
javier__>
Tenkawa: what bootloader are you using? nv-uboot, or the stock one
<
javier__>
Tenkawa: Ok, so a signed FIT
<
Tenkawa>
it boots up fine.. just doesnt setup the display correctly
<
Tenkawa>
I'm able to login and reboot it... just cant see
<
javier__>
Tenkawa: can you share your dmesg?
<
javier__>
that's with 4.5-rc1 and exynos_defconfig right?
<
Tenkawa>
I'm going to try "no" changes now
<
Tenkawa>
I did do a few settings changes
<
Tenkawa>
want to rule those out
<
Tenkawa>
I'll be back online tomorrow to post the results
<
Tenkawa>
dont want to delay you either
<
Tenkawa>
btw should i use snow or snow-rev5?
<
javier__>
Tenkawa: Ok, I'm about to leave but if you share your complete boot log and kernel command line
<
Tenkawa>
here's the command line
<
Tenkawa>
root=/dev/mmcblk0p3 rootfstype=ext4 rootwait ro init=/sbin/init rootflags=data=writeback,discard console=/dev/tty1
<
javier__>
Tenkawa: you said that you are using the snow dtb and that's the correct one
<
javier__>
Ok, that's seems correct
<
Tenkawa>
I've tried snow and snow-rev5
<
javier__>
Tenkawa: if you can share your dmesg output then we can get a clue
<
Tenkawa>
I'll build it exactly stock. I'll have to extract that ouot of a huge messages file..
<
Tenkawa>
I'll clean the logs for the next run
<
javier__>
Tenkawa: Ok, leaving for real now. But try 4.5-rc1 + exynos_defconfig (or multi_v7_defconfig) with no changes
<
Tenkawa>
for now i'll do some more tests.. I'll be back on tomorrow.. thanks for the help
<
javier__>
if you don't have display working then please share your kernel boot log
<
javier__>
Tenkawa: no worries

best i can tell so far is the devicetree definition for drm and the display might not be setup right here
<
Tenkawa>
comparing the 2 dmesg theres a lot more drm and video lines in the 4.4 kernel than the 4.5-rc1 one
