MK908V5 Kernel Source

[testuser0]

Hi everybody. i own an "MK908V5" (i checked it inside). I'm searching for a working kernel config. i compiled a working kernel from here https://github.com/tyeo098/MK908-Kernel-NAND. Ubuntu is booting up and everything is working good (Need to port mali Drivers after that). But my main Problem is flickering .... it is hard flickering .... Any advice for me ? My Thing is that i want to use an kernel which i compiled by myself so i can add modules and Change minor things. thanks in advance

Iirc the flickering is caused by to high or to low hdmi voltage, probably you can find something with that hint...

Hey. Thanks for the Response. Well... i'll check if i figure something out. I will post if i solved it. Edit: // I have cut out some dmesg from HDMI (finless Rom without flickering)http://pastebin.com/zJ4sPVWh have a look at DVFS MSG

So you have a v5 that means you got a 3188t chip limited to 1.2ghz?

Well... i dunno... here is the full dmesg from finless Rom with ubuntu running: http://pastebin.com/9xtcAz4V . i buyed it from **** last year from here http://www.****.de/itm/RK908-Android...item27d8905458 ... thats all i have... as i mentioned before the kernel which i posted runs... here is the dmesg from my compiled kernel: (i'll post later) .. i'm not able to get the dmesg completly.... has anyone compiled an kernel for mk908v5 ? i want vpu and mali get to work.... ubuntu runs very good but playback is impossible..... help

You could just check if your device reaches 1600mhz or not by using osmonitor or something else
If it does, it is a non t cpu which is good actually

Well. I do believe it does 1.6 Ghz. [ 0.866465] cpufreq: delete arm freq(1608000) [ 0.866504] cpufreq: delete arm freq(1704000) [ 0.866541] cpufreq: delete arm freq(1800000) I find this quite interesting: [ 0.866175] adjust table freq=1704000 KHz, index=1375000 mV to index=1350000 mV [ 0.866254] adjust table freq=1800000 KHz, index=1375000 mV to index=1350000 mV

I have no idea of kernel coding, but you have to be aware that the kernel is also compatible to the earlier non t versions of the cpu namely the 908v3 and v1 sticks. This means the frequencys will be in the code. The lockdown to 1.2ghz is made in v5 hardware by rockchip.

Hmm.... Anyway, i gor my kernel run on the device, hard flackering but i was able to get the dmesg: http://pastebin.com/Nsckb6CQ as you can see there are some errors. i would love to hear advices! thanks
