Alright I need some assistance. I used rkcrc to create a kernel.img to write to the kernel partition. I used dd to write it now when I attempt to boot up using ctrl+u it just dings at me and goes back to os verification off screen. Anyone have any ideals where I might have screwed up
<naobsd>
Anarchy: I couldn't understand this part "when I attempt to boot up using ctrl+u it just dings at me and goes back to os verification off screen."
<naobsd>
which device are you using?
<Anarchy>
hisense chromebook
<naobsd>
kernel.img format(rkcrc -k) is only for RK proprietary loader
<naobsd>
sorry
<naobsd>
kernel.img is only for RK proprietary loader for Android
<naobsd>
chromebook uses different loader (unless you replace it)
<naobsd>
I don't have any chromebook, so I'm not sure about it

Hi guys
<marcr>
Any news about nand controller driver?
<marcr>
Can anyboty clarify if all rk3xx soc's has the same version of nandc ip? Because i see that there is doc in px2 trm for controller (v6.0.0 at least)
ckeepax has joined #linux-rockchip
<marcr>
Does anybody started working on the driver ?
<marcr>
I ask because i've read the docs 5 times now and i'm thinking about writing it myself. There are still parts i don't understand (ECC) but i'm getting closer ...
<marcr>
... so if someone have some info in this topic please share :) ... i'll be grateful

<rperier>
yeah that's this one, the unique commit with "WIP" in the commit log :p
<rperier>
(that's because my recipe in yocto is not committed yet into meta-rockchip, but I am sure that it is this one)

I did not re-test recently, I just know that there are some pending fixes about usbphy and usb in rockchip. Last time I had a look at it, it was supported on old socs no? (in fact, I was a bit disconnected these days, because I had new jobs opportunities...)
<BorgCuba>
when I last tested it (about 3.18) it was not working
<BorgCuba>
something related allocating fifo buffers failed
<rperier>
you should retry with a recent kernel, lastest mainline is 4.3 now :)
<BorgCuba>
Indeed, hopefully I find my dts file again ... for me it always takes some time to remember all that after a few months of absence
<aborche>
rperier, and where this latest mainline located ?
<aborche>
:)
<aborche>
on which git ? :)
<aborche>
BorgCuba can you share your dts ? :)
<aborche>
for testing ofcourse

current 3.18.25 cannot boot with radxarock-lite config for 3.18.11. some error about ext4 partition
soimless has joined #linux-rockchip
<BorgCuba>
aborche, sure, when I find it
<BorgCuba>
btw, I have radxa lite here too
<BorgCuba>
aborche, are you sure the ext4 problem is related to the dts?
<aborche>
yesterday we make a development board from cx919 fake - D908. and now i see all log data
<BorgCuba>
what are your kernel parameters and how does your sd-card look like?
<aborche>
BorgCuba, i don't know. but 3.0.36+ boot at this sd normally
<BorgCuba>
make sure you have something like "root=/dev/mmcblk0pN" (N = your partition) and "rootwait" in your kernel parameters
<BorgCuba>
looks like I deleted all my local linux-next copies
<aborche>
;(
<aborche>
BorgCuba, this parameters exist in parameter.img
<BorgCuba>
are you sure that the mainline kernel reads these parameters? I would try to hardcode them into the kernel (make menuconfig)
<BorgCuba>
wait, I think uboot does this
<aborche>
where i can get rk3188-box.dts for clean testing ?
<mmind00>
mrueg: that patch seems to be the talk of the day :-D
<mrueg>
mmind00: commit message is golden :D
<mmind00>
mrueg: yep
<aborche>
guys how i can convert back decompiled dtb tree ? with pin aliases and etc ?
<mmind00>
aborche: you cannot fully restore phandles from a compiled dtb ... to get a somewhat-similar source to your dtb, "dtc" is still the program to use
<aborche>
i know, but values which i get from compiled dtb from kernel image differs with values which i get when compile my tree
<aborche>
and i can't understand where is the problem ? different version of kernel or different version of includes
<aborche>
i think dtb tree have cross compatibility between kernels. or not ?
<aborche>
as example slitaz image as they say, succesfully booted on radxa rock and screen work is ok
<aborche>
and at radxa forum julien run 3.10 at radxa rock with worked hdmi
<aborche>
and i don't understand - how ? :(
<rperier>
everytime I read "dtc" (for the devicetree compiler), it disturbs me... do you know, what does it stand for in french ? that's an acronym... like "in your ****" but in french... xD
<rperier>
(I am serious, I know that dtc is not french at all, but you know... sometimes you find funny name like this one :D)
<aborche>
also. kernel must use gpt partition or no ?
gb_master has joined #linux-rockchip
<aborche>
current kernel, rockchip_defconfig config, rk3188-radxarock.dts
<mmind00>
aborche: it already detected the one partition, so part-table should be ok already ... is your partition on the sd-card actually ext4-formatted?
<aborche>
yep. this partition boot is ok when kernel is 3.0.36+
<aborche>
maybe i should use boot option with partition name ? without direct set to first partition ?

BorgCuba, i cannot boot any other kernel instead 3.0.36+ at my board.
<via>
are there any issues with building an upstream linux kernel like 4.3 for the c201 chromebook (rk3288)? e.g. can i just use the stock config (plus make oldconfig) and the speedy dts?
<BorgCuba>
aborche, I think I will try it too ...
soimless has joined #linux-rockchip
<aborche_>
BorgCuba, thx. i'm trying get a worked version of any kernel last two week. and without any positive result :(
<aborche_>
i found image from Slitaz, and get dtb file from it, but boot is unsuccesful :( I think many problems linked with dts file. freq, voltage, interface speeds
<aborche_>
but without any worked image i cannot make some steps for migrating system to this kernel and test it.
<aborche_>
hm. this config content similar as rk3188-radxarock.dts
<BorgCuba>
aborche, did you use a defconfig to configure the kernel?
JohnDoe_71Rus has joined #linux-rockchip

is there no support for the act8846 in 4.4-rc6?
<BorgCuba>
I can see TI TPSxxxxx but no act8846?
<BorgCuba>
hmm, is it maybe compatible to act8865?
<mmind00>
via: depends on what level of functionality you need ... aka the eDP driver (needed for the internal display) is not yet upstream, but sitting on the mailinglists still
<mmind00>
mmind00: so with current mainline you'd get hdmi-output only
<mmind00>
via: ^^ not sure, why I addressed that to me ;-)
<via>
mmind00: hmm. i washoping enabling the rockchip drm would allow the use of the framebuffer
<via>
so that doesn't work?
<via>
thats kind of a dealbreaker
<mmind00>
via: the low-level stuff works, just the outputs are still a bit limited (aka hdmi)
<via>
doesthe 4.2somewhat-stable tag have edp support?
<mmind00>
via: that too, but still with the old edp implementation ... both branches linked above do use the new dp driver, that will hopefully make it into mainline soo
<via>
ok
<via>
so i guess you keep the somewhat-stable branch up to date, andi could just occasionally pull/build?
<mmind00>
via: bleeding edge is more like it ... that is my dev-/integration-branch but where I try to stay true to its name ;-)
<via>
cool. yeah,i only expect so much stablity from a setup like this..., but i guess more testing is better anyway
<mmind00>
via: also I keep the gpu-support in there (which cannot go into mainline at all currently)
<via>
rockchip-drm?
<via>
or something else
<mmind00>
via: nope, the mali stuff
<via>
ah. does that require firmware outside of this?
<mmind00>
via: a userspace binary libGLES* + x-server
<mmind00>
via: see mali-driver and xf86-video-armsoc repos on github
<via>
ok, thanks
<via>
wasn't there an effort to make an open soruce mali driver?
<via>
lima
<via>
well that project isn't looking like its gotten a lot of work
<mmind00>
also, lima was for the mali utgard series (200, 400) ... there was once a presentation about an unpublished driver called "tamil", for the mali midgards (like the T764 in the rk3288)
<Wizzup>
it got a lot of work, it is not visible, via
<via>
hmm, i don't know what to think about that, unreleased open source code? that whole project seems to have some political issues, at least thats what turns up when googling
<via>
either way, i'll stick with the blobs for the moment
<aborche_>
BorgCuba, rockchip_default or radxarock_default
<BorgCuba>
aborche_, I cannot find this in 4.4-rc6
<aborche_>
only from rockchip.fr
<BorgCuba>
quite old
<BorgCuba>
I'll try with that defconfig
gb_master has joined #linux-rockchip
<via>
just build and installed a kernel from that branch and i don't appear to have a framebuffer. this happens to me a lot <_<
<via>
mmind00: looking at the kernel log, it definitely detects the framebuffer and says its setting up a 1024x768 fb, but i have a black screen... any idea what im doing wrong?
<mmind00>
via: you should also see messages about the hdmi + dp around that area ... what devicetree did you use?
<via>
i doubt this is relevent, but should console=tty1 for the linux cmdline?
<aborche_>
BorgCuba, you use radxa board or tv stick ?
<BorgCuba>
radxa lite board
<BorgCuba>
aborche_, what hardware do you use?
<mmind00>
via: can you try increasing the startup-delay in the panel_regulator node (say to 200ms ... value 200000), just to check that the panel doesn't take to long to start
<aborche_>
D809 stick
<aborche_>
similar radxa rock lite board without rk616 and rk1000
<aborche_>
this is my fork from radxa with minor changes
<mmind00>
via: I have reports for speedy being able to do the 50ms, so I'd like to find some sort of minimum for everybody ;-)
<BorgCuba>
aborche_, what do you want to do with your device?
<aborche_>
BorgCuba, a big problem with 3.0.36+ - old mali drivers and very slowly render in chrome and nwjs
<via>
well, 80 ms works
<via>
i'll keep going down and report back
<aborche_>
BorgCuba, i need fast Xorg screen driver with video hardware acceleration
<BorgCuba>
aborche_, I am aiming for retroarch on framebuffer (with mali)
<BorgCuba>
got a pretty bad glmark2-es score like maybe 40 or at least < 100 while the orangepi-pc I recently received has a score of about 480pts (only MP2)
<aborche_>
BorgCuba, olegk0 finished yesterday work with vdpau driver
<ssvb>
BorgCuba: gprof can't be used for profiling the kernel
<aborche_>
BorgCuba, which config you use for your board ?
<aborche_>
system boot is ok ? or halt ?
<aborche_>
guys i have a question. in linux-next kernel operation with ramdisk(initrd) has been changed or no ? why kernel cannot find attached ramdrive ?
akaizen has joined #linux-rockchip
<aborche_>
and unsuccessful boot can be fired if i use extended ext4 partition instead primary partition ?
<BorgCuba>
aborche_, I used the defconfig from rockchip.fr (you pointed me there)
<BorgCuba>
and the radxa dts file that comes with 4.4-rc6
<aborche_>
hm. also i'm found at radxa forum fresh config for radxa rock lite from hipboi.
<aborche_>
a big tar file contains config for radxa-lite and broken dts. dts file with k31811 contains correct device tree
<aborche_>
at my d809 i cannot boot, kernel panic fired when kernel trying to boot
<via>
im having trouble with the rockchip sound now...but i'm not sure how to debug this. if i use mplayer with -ao alsa (i copied ove rthe ucm profiles from chromeos), output just hangs
<via>
i can show the mixer controls though
<aborche_>
i think problem in pulseaudio. when you change X session, pulseaudio is not stopped by default, and when Xsession started - another copy of pulseaudio started too
<mmind00>
via: yep that is the current state of affairs ... on the chromeos-partition supposedly is something called an ucm-profile for alsa ... but I don't think anybody has looked into that yet
<via>
mmind00: yeah, i copied those over as per the debian instructions
<via>
so... hmm
