CS918 - help to find the right Firmware, Kernel vyx_cs918 v2_1

[no_spam_for_me]

@davy39
You are right... I forgot the settings at android

[d33]

I'm watching this thread now.

If anyone can provide DMESG and GPIOs from a working 'stock' kernel then I will be able to get a custom one built.

Current test kernels are here

Davey39's device seems to have a problem with the standard power regulator chip which is odd. It reports no ACT8846 chip with stock and custom kernels. Currently, we don't know if this box/stick is 'special' or damaged.

A way to get GPIO at stock kernel

Hi,

For linux/debian/ubuntu users, I've just written a bash script that automatize everything for getting the gpio dumps, even enable and disable wifi/bluetooth.

See here for more informations :

https://github.com/davy39/rk3188-gpio-dump

Do not hesitate to test it and report any problem or some modifications.

I'm not used to windows scripting but i'll have a look to translate it into a .bat script.

Thanks

NICE
I think #69 (if something like 'wget' at windows also exist/available) or ~#96 till end will also work at windows at a cmd (ok, the function 'dump_gpio' could be a problem ) ...

wow it`s go forward.

thanks to Creatobis


i will try i few hours your Custom Firmware from 2.3 on 2.1 and the Water xbmc and report.

[GabberG]

Small retreat: though XBMC also works in my FW, however playback in him too is far from an ideal. Default android video player and the more so MX Player cope with playback much better. I didn't find solutions for XBMC yet

you mean water xbmc or original?

[Creaturebis]

you mean water xbmc or original?

Any of XBMC versions at all doesn't work at the last version of an stock FW for some reason, except wasser. When playing any video only the green square on all screen, with a soundtrack is displayed! Therefore, I replaced preset XBMC with wasser XBMC.

By the way, on the previous page davy39 described this malfunction too in this stock FW:

Hi guys,
I finally got a screen to test my vyx_cs918_v2_1 box.
Reading this thread I tried to install Q7 lewy firmware but surprisingly I got an error message while flashing it to the box with upgrade_tools...

Finally I installed the last stock rom cyxtech_cs918_8723_box_140731_8G2G.rar

http://pan.baidu.com/wap/link?uk=775698826&shareid=354074169&third=0

Everything works out of the box (wifi, eth, blutooth...) except the original xbmc version...
I installed the last wasserXBMC which is able to read 3D fullHD mkv quite fluently :

[GabberG]

I have installed the stockfirmware and Water xmbc - Stutter
I have installed your custom and water xbmc - Stutter


i have flash back Q7 from lewy with lan only
the playback and HD Streams are beautyful.
its my final Solution.

what is the Different from Q7 lewy and the stock?
The anTuTu Benchmark is the baddest - but has the best Playback

I think the vsync fix for the orginal kernel dont work with the patchomatic

Problem of XBMC solved

I ask to pay attention that micro stutters when playing in XBMC aren't a problem of vertical synchronization! As I already told earlier, in other media players video playback of files ideally.
The problem when using a XBMC is that in a stock FW the nominal frequency of the CPU is lowered. Someone already said earlier that freguency is established at level 1Ghz that obviously doesn't suffice for XBMC. For myself I didn't see the reasons to unblock her to level 1.6Ghz (nominal frequency), proceeding from thought that for cooling it probably the best option. Nevertheless, I patch a kernel with new params: CPU - 1608mhz, GPU - 798mhz, and it appeared enough for smooth playing in XMBC. Now behind my back normally playbacking "Back To the Future" in 1080p, I test... Soon after, today, I will lay out the new version of assembly.

[GabberG]

The stock fw run on 1008mhz
q7 from lewy on 1400mhz (without Therical Problems)

I have Used patchomatic to overclock the stock Kernel (without errors) but its Show me always 1008mhz

Cyxtech CYX cs918 v2.3 stock FW repack

Yes, CPUz shows me the same (1008Mhz). Nevertheless productivity in Antutu grew a little, and with playback in any player (yes, XBMS too!) there are no problems. About four hours of uptime I have no problems, all ok. So here is my new build, if anyone need this: https://yadi.sk/d/yC4OI9mkaTqAd

I have exactly all the problems you had, but my PCB is 2.1. I've installed all the FWs and have a decent playback, but they turn off after a couple of minutes when using XBMC.

Do you have any tip for me? Will your fw work for me?

Thank you for your time to make stock firmware usable. I have problem with it, after I updated device with your firmware, there is no root option. Yes, i have supersu, but it ask for update binary and after I select ing normal update, it shows installation failed, so...
