MK808B KitKat kernel [Working WiFi & BT]

[markust]

Does anyone know if Dumonde´s kitkat ROM supports "ROCKCHIP HDMI PASSTHROUGH"?

[prahjister]

I have an MK808B (original, with RK903 chip set, purchased from Geekbuying in June 2013). As my on board WIFI chip is fried (OTG cable took a dip in fish tank under TV). I have purchased an external chip which is a Realtek RTL8188CU. I have this working fine with Fineless ROM 1.7 using a driver from http://www.armtvtech.com/armtvtechfo...ile.php?id=180 However I would like a more up to date ROM. I see that BalintBanyasz has a kernel for KitKat that should work with this WiFi chip. However I have tried the following roms...

- Dumonde's MK808 ROM (rooted) --> two penguins
Downloaded from https://mega.co.nz/#!VdljCDxY!94jrZu...JExYKt8bitPSqw as link in OP no longer works
- mShomari's Kit Kat 4.4.2 RK3066 --> runs but screen keeps flashing with and android in top left hand corner of screen and can’t do anything
- Smallart Uhost2 KitKat (U2.442.000.11.140327) --> can’t try as links in OP no longer working.

I have tried loading Dumonde's and mShomari's both are single img firmware with AndroidTool v2.1 both appear to include the new bootloader in the image.
Other users such as totor54 rk903 and Lude have had the same problems loading KitKat . Others such as Lokotito have been able to boot Smallart ROM but unfortunately the link in the OP no longer works so I can’t try it.

With any Android ROM's for 4.2 or 4.1 I have never had a problem flashing them and running them. I have no problem going back to a jellybean ROM they always boot. Any ideas what I should try to get KitKat running?

Try my v5 based off latest stock

Dear Prahjister

Thanks for your good Work!!

Your Version(V5), already has the fix for the wifi?when turning on the wifi, low to the perfornance mk808b.

Many Thanks

Prahjister's V5 ROM is a Jelly Bean 4.2 ROM for the new MK808B V5 devices with Realtek wifi.
If you have the original device with RK903 wifi/bt then you'll lose wifi and bluetooth if you flash his ROM.

Hi,

any changes from the RK903 chip?

Thanks

I'll have another look this weekend, but I haven't had any luck so far.

Perhaps another kernel/ROM developer with more experience could solve this bug.

Here is the summary of the problem:
The problem is most likely caused by the RK903 driver. It has a process named dhd_dpc that uses ~30% of the CPU presumably because of its frequent software interrupts (softirq, sirq). When only bluetooth is enabled, the cpu usage is normal. You can find several dhd_dpc related topics on Google but none of them has a solution.

I'm not even sure whether it's a kernel problem or a ROM issue. Perhaps the best thing would be to build a complete RK903 ROM from the Rockchip sources.

I will Wait for solution...

How's your weekend ?
Any luck with the RK903 Kernel ?

[triancus]

This Kernel works with TP-LINK TL-WN722N?


Thanks for your work!

Using this setup on my mk800 non b. I am trying to setup a vpn but my vpn is failing to connect. Did some research and have found out that the tun driver needs to be enabled. see below. Any tips to how this can be done? Where is the TUN driver located and how can i change from =0 to =1

@BalintBanyasz

I was digging around and found this commit involving dhd_dpc priority. What would changing that from 0 to the suggested 1 in the commit accomplish?

Всем здорово, кто нибудь победил dhd_dpc на rk903 (MK808B) ?
Ядро rockchip-3.0-rbox-kk с патчем "MK808B_RK903_MAWKISH_PATCH", на нем работают Bluetooth и WiFi.
При запуске интерфейса wlan0, в top висит процесс dhd_dpc потребляющий 30% процессора. При этом нагружаются оба ядра RK3066.
Пробовал ядра от omgamoon, но комбаин (rk903) не инициализируется при загрузке ядра, хотя rkwifi 100% рабочий, так как я его переносил в rockchip-3.0-rbox-kk.
Если есть у кого то опыт решения данной проблемы, поделитесь пожалуйста с общественностью.

Device: MK808B BT/WiFi(RK903)
I have the problem of high load CPU, process dhd_dpc.
Loading 30% of CPU.
I have kernel 3.0.36 (rockchip-3.0-rbox-kk) + patch "MK808B_RK903_MAWKISH_PATCH".
Bluetooth working not loaded cpu, but WiFi working and high loaded cpu...
I tried to use kernels "omegamoon 3.0.8 and 3.0.101", bluetooth and wifi not init.
My MK808B gpio 1in1 how to omegamoon, but don`t work init

We need professional help to fix this problem.

Hi,
I found this (http://forum.xda-developers.com/wiki..._CarPad_NU3001
) project, it's KitKat ROM for RK903 WiFi chipset. May be somebody can extract WiFi related stuff from there and please make a working KitKat ROM ?
I tried to use their kernel but it wont boot. Probably because of the fact that they use it for RK3188 SOC.
Thank you!
