hi ll
<Tenkawa>
anyone awake yet?
<Tenkawa>
I made some progress
<Tenkawa>
nw the kernel just panics
<Tenkawa>
(or never finished booting) last line is/l
<Tenkawa>
er :
<Tenkawa>
Stashed 20 records
<Tenkawa>
might just be a bad kernel config
<Tenkawa>
building a new one now
<Tenkawa>
anyone got a known good .config?
<javier__>
Tenkawa: what is your device and which tree and branch are you using?
<Tenkawa>
snow chromebook xe303c12 3.14.0
<javier__>
why 3.14.0?
<Tenkawa>
was starting with the one on the webpage
<Tenkawa>
got a recommendation?
<javier__>
Tenkawa: yes, 3.18 + my topic branches
<Tenkawa>
oh
<Tenkawa>
i'm checking /topic and all I see is Wizzup's
<javier__>
branches wip/exynos/dp-integ and wip/exynos/wifi from git://cgit.collabora.com/git/user/javier/linux.git will give your working display and wifi
<Tenkawa>
oh sweet
<Tenkawa>
you got a defconfig in there too?
<javier__>
sorry I meant git://git.collabora.co.uk/git/user/javier/linux.git
<javier__>
yes, exynos_defconfig
<Tenkawa>
nice
<Tenkawa>
ok let me try that out
<Tenkawa>
got 2 computers out which makes this a lot easier
<Tenkawa>
cloning now
<Tenkawa>
(git)
<Tenkawa>
javier__: any gotchas to watch for?
<javier__>
not really, it should just work
<Tenkawa>
sweet
<Tenkawa>
I so want to try out something newer than 3.8 on this box
<Tenkawa>
I really use this a lot
<Tenkawa>
I'm also working on getting linux support working in a Winbook TW100
<Tenkawa>
Intel Baytrail with the efi bug :(
<Tenkawa>
otherwise it would run fine
<Tenkawa>
only got 9% of the files so far :(
<Tenkawa>

building now
<Tenkawa>
ummm
<Tenkawa>
whats the git checkout tag I need to use?
<Tenkawa>
it comes out as 3.14.0-rc2 default for me
<Tenkawa>
git --tag doesnt list 3.18 in there
<Tenkawa>
unless I did something bad wrong
<Wizzup>
git checkout -t origin/dp-integ
<Tenkawa>
ok let me try that
<Tenkawa>
not happy about that at all
<Wizzup>
?
<Tenkawa>
let me get the output
<Tenkawa>
I shoudve cloned via git clone git://git.collabora.co.uk/git/user/javier/linux.git or did I completely mess it up
<Tenkawa>
no branches listed in my repo either
<sjoerd>
what does git branch -r tell you ?
<Tenkawa>
ahh haaa
<Tenkawa>
its origin/ip/exynos/.....
<Tenkawa>
r wip
<Tenkawa>
ok thats looking a lot better
<Tenkawa>
sjoerd: thanks
<Tenkawa>
bit rusty on git
<Tenkawa>
its checking out the changes now
<sjoerd>
normally git would figure out it needs it from the remote
afaerber has joined #linux-exynos
<Tenkawa>
weird
<Tenkawa>
sjoerd: well at least now its going :)
dlezcano has quit [Ping timeout: 252 seconds]

reminds me of my source code control admin days in the early 90
<Tenkawa>
's
<Tenkawa>
ooh that looks a lot better
<Tenkawa>
build time
<javier__>
Tenkawa: I haven't updated the master branch in my remote for a while
<Tenkawa>
ahhh
<javier__>
Tenkawa: that's why I told you the branches you had to checkout :)
<Tenkawa>
DOH
<Tenkawa>
it got blocked out by server messages
<Tenkawa>
in my scrollback
<Tenkawa>
my apologies
<javier__>
Tenkawa: git clone -b $foo git://.. would had made the trick
<Tenkawa>
i didnt see the wip at all until I looked at my chan log
<javier__>
but I usually just do git remote add foo git://foo & git remote update foo
<Tenkawa>
uggh
<Tenkawa>
I hate when it does that visual override
<Tenkawa>
my bad
<Tenkawa>
Its compiling now :)
<javier__>
cool
<javier__>
gotta leave for today, bye!
<Tenkawa>
this is going to be so cool if it works
<Tenkawa>
cheers. thanks again for all the help

amitk has quit [Quit: leaving]
<Tenkawa>
anyone know what loadaddr I should use offhand for the build?
<Tenkawa>
I think its 0x400800 (at least thats what i have
afaerber has quit [Ping timeout: 252 seconds]
<Tenkawa>
here we go
<Tenkawa>
lets see if it will boot
<si1v3r>
good luck!
<Tenkawa>
it starts kernel then appears to have same panic/hang
<si1v3r>
can't mount root?
<Tenkawa>
letI dont get to the kernel even yet.. let me make sure my dtb is updated
<Tenkawa>
well thats "closer"
<Tenkawa>
it loads up the uImage then reboots
<Tenkawa>
never does hit the kernel though
<Tenkawa>
hmm
<Tenkawa>
I wonder if my boot cmdline is wrong
<Tenkawa>
anyone got an example handy?
<si1v3r>
Mine should be on the wiki
<Tenkawa>
let me take a look
<Tenkawa>
darn.. just resets
<Tenkawa>
let me take out the bootargs and see if I can get it to panic
<Tenkawa>
i see it flash by the device tree then it reboots
<Tenkawa>
i see it flash by the device tree then it reboots
<Tenkawa>
oops
<Tenkawa>
si1v3r: I should be using the uImage even with nv-uboot right
<Tenkawa>
?
<si1v3r>
uimage for uboot
<si1v3r>
yes
<Tenkawa>
it seems the devicetree changes what it does
<si1v3r>
yes that's the attempt at using one kernel for more than one device
<Tenkawa>
I wonder If I'm using the wrong one
<si1v3r>
it's built at the same time as the kernel
<Tenkawa>
yeah
<Tenkawa>
that appears to match up
<si1v3r>
brb
<Tenkawa>
its going to be something tiny
<Tenkawa>
I can almost gurantee
<Tenkawa>
so close to reading what it says
<Tenkawa>
let me see if I vid it
<Tenkawa>
er I can
<Tenkawa>
got it!!
<Tenkawa>
failed to add board information to fdt: fdt_err_notfound
<Tenkawa>
fdt_system_setup() failed before
<Tenkawa>
wow thats awesom
<Tenkawa>
cantb believe this camera grabbed it quick enough
<Tenkawa>
now to troubleshoot
<Tenkawa>
probably got an address wrong

darnit
<Tenkawa>
i wish I could igure out why fdt is erroring
<Tenkawa>
I feel like I'm so close
<Tenkawa>
does it matter I'm not fatloading any of this and doing it all with ext2load?
<Tenkawa>
oooh
<Tenkawa>
I think I might know why
<Tenkawa>
maybe not :9
<Tenkawa>
thought my dtb may have been skewed
<Tenkawa>
hmmmmm
<si1v3r>
Is there an error on the screen when it fails?
<Tenkawa>
tI typed it above
liquidAcid has joined #linux-exynos
<Tenkawa>
that FDT one
<Tenkawa>
it reboots immeditely
<Tenkawa>
I had to photo that
<si1v3r>
gotcha
<Tenkawa>
I got a feeling I'm so close.....
<si1v3r>
Are you doing two ex2loads and a bootm?
<Tenkawa>
yes
<si1v3r>
you might want to run mkimage on your kernel image and see if it has the dtb built in
<Tenkawa>
I just did
<si1v3r>
are you loading the dtb to 400000
<si1v3r>
?
<Tenkawa>
got the same stating kernel then bunch of timer summary then accumjulated time finally stashed 21 records
<Tenkawa>
no
<Tenkawa>
00400800
<Tenkawa>
I was wondering about that too
<si1v3r>
400800 is for the kernel
<si1v3r>
the dtb is loaded to another address
<Tenkawa>
right
<Tenkawa>
just a sec
<Tenkawa>
let me check what they are set to
<Tenkawa>
I got rid of the dtb error
<Tenkawa>
by making a vmlinux.uimg with mkimage
<Tenkawa>
now it boots up to that old panic
<Tenkawa>
o
<Tenkawa>
k
<Tenkawa>
dt - 0x43000000
<Tenkawa>
fdtaddr - bda3dbdc
<Tenkawa>
need any more
<Tenkawa>
?
<si1v3r>
those look wrong to me
<si1v3r>
but I can't get to my notes at the moment
<Tenkawa>
well darn
<Tenkawa>
ok.. let me google a bit
<Tenkawa>
hmmmmmm
<Tenkawa>
just a sec
<Tenkawa>
minimally ftaddr appeared to not match up
<si1v3r>
I don't think the actual value is important as long as it's in the right range and is consistant.
<Tenkawa>
I think its my loadaddr
liquidAcid has quit [Read error: Connection reset by peer]
<Tenkawa>
if I move it I can switch the behaviour
<Tenkawa>
uggh
<si1v3r>
you only have 3 moving parts, so it's not impossible
<Tenkawa>
I just wish I could explain this weird error
<si1v3r>
link a picture
<Tenkawa>
nothing to send it with
<Tenkawa>
long story
<javier__>
Tenkawa: can you please share your u-boot bootcmd and the command you are using to create the uImage?
<Tenkawa>
sure
<Tenkawa>
let me type them out
<Tenkawa>
mkimage -A arm -O linux -T script -C none -d boot.scr boot.scr.uimg
<javier__>
Tenkawa: what I said, you need to load a device tree from your media and pass it to bootm or append the DTB to the zImage and then generate the uImage
LanDi has joined #linux-exynos
<Tenkawa>
Ahhhh
<javier__>
Tenkawa: you have also to check the value of your ${loadaddr} u-boot env var and be sure that the address to load the FDT makes sense
<Tenkawa>
so do the cat dtb >>zImage trick then generate a new uImage?
<javier__>
yes, that's an option if you don't want to change your current u-boot commands
<Tenkawa>
ok
<javier__>
the exynos_defconfig has all the needed kconfig symbols enabled to make that work
<Tenkawa>
let me try it... ifit works I'll make the nvram changes
<javier__>
Tenkawa: you can't build the uImage with make though since you need that intermediate step so build a zImage, append and then generate the uImage with mkimage
<javier__>
passing your load and entry point address as mkimage arguments
<Tenkawa>
yep
<Tenkawa>
got it
liquidAcid has joined #linux-exynos
<Tenkawa>
trying .....
<Tenkawa>
fdt and efi are not my friends
<si1v3r>
100% different beasts.
<si1v3r>
by completely different flavors of idiots....
<Tenkawa>
no no.. i mean just in general
<Tenkawa>
ok here goes the next test
<Tenkawa>
nope
<Tenkawa>
let me try to add the fdt to the boot line
<Tenkawa>
Think I found it!!
<Tenkawa>
loadaddr typo
<Tenkawa>
omg i hope this is it
<Tenkawa>
should it be 0x400800 or 0x40008000?
<Tenkawa>
I assume this matters
<si1v3r>
super important
<Tenkawa>
would explain my load problem
<Tenkawa>
omg I think this is it
<Tenkawa>
find out shortly
<si1v3r>
great success?
<Tenkawa>
sstill recombining dts/kernek
<Tenkawa>
er l
<Tenkawa>
is 0x40008000 the right value?
<si1v3r>
was for me but I didn't combine

that missing 0
<Tenkawa>
2 0's was the whole problem
<Wizzup>
awesome!
<si1v3r>
shoopdewhoop
<Tenkawa>
sorry... I'm really excited
<Tenkawa>
now I can do some heavy kernel work
<si1v3r>
dude. totally.
<Tenkawa>
I am so sorry i missed that there was a 0 missing
<si1v3r>
worry about buggin javier not me. heh
<si1v3r>
he's the kernel dev

is going to do snow tonight as well

hopefully ;)

repos ubuntu installer issues for werk
<Tenkawa>
I really wanted to get this box back to being able to do hardware work
<Tenkawa>
I just can't believe 2 0's
<Tenkawa>
thats all it was
<Tenkawa>
uggh
<Wizzup>
write down your steps :)
<Tenkawa>
haahaa I will try
<Tenkawa>
I am not committing anything to mmc and nvram yet so I should be able to
<si1v3r>
No scroll back, copy them, strip the crap, paste somewhere. :D
<si1v3r>
holy. crap. If you attempt to manually install ANY package at 14.04 server install time, it dies.
<javier__>
Tenkawa: glad that you go it working
<Tenkawa>
now I need to tune this kernel some (wifi is currently missing)
<javier__>
Tenkawa: if you cherry-pick the first patches of my wip/exynos/wifi, you should get wifi working on snow
<Tenkawa>
ok
<Tenkawa>
switching it to use faster storage for root
<Tenkawa>
thats better
<Tenkawa>
much better :)
