Building 4.4.2 kernel for RK3188-T with MT6622N and ESP8089 drivers

[atatek]

Hi,

I'd like to build a kernel for my device.
I wanted to by a CX-919, and got this new MK809III stick mentioned in thread: http://www.freaktab.com/showthread.p...N-with-ESP8089

After some research I've found that there's a build configuration automation (https://github.com/phjanderson/marvin) and a kernel for the chip (https://github.com/linux-rockchip/kernel_rockchip) and there's also a configuration file for the wlan chip in the kernel_rockchip repo. (ESP8089)

Is there a way to build a kernel for this device? If I build a kernel will it work with other ROMs?

I've also found out that the radxa rock rom starts on the stick, but no wlan/bt driver in the kernel. Can I patch it someway?

Regards,
atatek

When I run make from marvin I get an error:

Then build fails. What is the problem?

I'm following, but I still want to build it.
So any help with it would be appreciated.

To be honest, probably wasting your time.

The kernel doesn't seem to work on anything bar the stock rom or you'll lose wifi and bt, so you're much better off spending time working on a rom then the actual kernel itself, as that is only half the battle with these devices and there is already work being done on an unlocked kernel.

Ok, as I see D33 has already built a working kernel to the device.
Many thanks to him!

I think I can build the kernel img from that source.

Good luck.

The problems you had above come from declarations made in the wifi declaration blocks in the SDMMC files. Obviously I've fixed them in the source I maintain.
