paccer: you can try bqcurie2, marsboard or rayeager dts for start. Also on this photos i don't see the name of the power pmic. If its tps you might be in luck with this device trees.
<mrjay>
paccer: finding gpios might be a little tricky. Kernel source for this device would help much

eballetbo: did you copy, if you have time to confirm I'll bug the patch authors
<EmilKarlson>
well, I'll bug them anyway, but would be nice to have confirmation that I did not do a silly

paccer: one more thing ... are you trying to boot android with more up to date kernel or are you trying to boot some linux distribution?
<paccer>
plan was to boot linux
<paccer>
you're getting my message when you're disconnected, right? ;)
<paccer>
it seems like it
<mrjay>
nope ... but i'm checking the logs
<paccer>
exactly, so you see them ;)
<mrjay>
yep
<mrjay>
to boot modern kernel you need kernel with enabled rockchip modules plus device tree
<paccer>
i've been using the mmind repo and pretty much following the rockchip wiki instructions with minor adjustments
<mrjay>
success?
<mrjay>
with success?
<paccer>
haven't had time to mess too much with it since my previous messages... had some problems generating the recovery.img image
<paccer>
there seems to be a lot of different tools out there that do the same, some outdated, some doesnt work, some for windows, some for linux
<paccer>
but i haven't messed with it too much since i built mainline kernel... i will definitely when i have time tho
<mrjay>
paccer: thanks ... everything looks good ... i don't know why this doesn't work
<paccer>
something tells me its related to the premature end of file error
<paccer>
could perhaps be because boot != recovery
<mrjay>
it might ... you could flash it as boot partition and check it
<paccer>
hmm, probably should try that
<paccer>
just been trying to preserve the original android installation for now
<mrjay>
you can backup boot partition
<mrjay>
!!! :)
<paccer>
of course ;)
<paccer>
more of a dual boot thing i was going for, but i could always restore i guess
<paccer>
this device seems quite hard to brick :P
<mrjay>
yep ... there is always mask rom mode :)
<paccer>
thing is, i dont know how to get into mask rom mode yet :P
<paccer>
except i can boot there from android

<mrjay>
you might short exported header between nand and "2012..." label
<mrjay>
it would be my first guess :)
<paccer>
already hacked a female pinheader into the side of the tablet for serial port, might as well add a button too ;)
camus is now known as kaspter

dumping the boot partition and writing it back doesn't give premature end
<paccer>
writing my custom image gives premature end
<paccer>
so something seems to be up with that
<paccer>
should probably go through that process again from the start
<paccer>
unless of course the premature end just means image < partition
vagrantc has quit [Ping timeout: 264 seconds]
vagrantc has joined #linux-rockchip
<paccer>
ah yes, thats it
<paccer>
premature end of file is non fatal and means image is smaller than partition, which is fine
<mrjay>
is it booting?
<mrjay>
ah ok
<paccer>
nope, still just black screen
<paccer>
and no output
<paccer>
i am out of time for now, but i will have another go at it very soon... thanks a lot mrjay! you've been very helpful :)
<mrjay>
you can check "console=ttyS2,115200 earlycon=uart8250,mmio32,0x20064000" as compiled in command line CONFIG_CMDLINE="console=ttyS2,115200 earlycon=uart8250,mmio32,0x20064000"
<mrjay>
cheers!
<paccer>
mrjay, as in.. add it to kernel config?
<mrjay>
yep ... by "make menuconfig"
<paccer>
i will try asap :) thank you
<mrjay>
