HDMI CEC

[ayufan]

I did find out this thread: http://forum.armbian.com/index.php/topic...er-for-h3/

It implements HDMI CEC driver for Allwinner H3 which appears to be very similar to Allwinner A64.
I tried to compile that and I even started receiving some messages from my TV.
I was unable to send anything, but maybe someone is willing to try this two branches and fix it themselves:

You have to compile Linux kernel, compile .dts and patch libcec with this patch: http://sunxi.das-eckchen.de/sunxi_libcec.patch.

When you `modprobe hdmi_cec` you should start seeing something on `dmesg` and when execute `cec-client`.

I managed to advertise HDMI-CEC from Pine and run cec-client.

Yay!

I can receive keys from my TV.

The next step would be to write Android Driver for HDMI CEC: http://androidxref.com/5.1.1_r6/xref/har...hdmi_cec.h

[ayufan]

I wrote really simple driver which implements Android HDMI-CEC controller: https://github.com/ayufan-pine64/android-hdmi-cec-sunxi

I did not yet have a time to test it.

Great Work! Please let us know how it works. Is there anyway to add it to the currently available android images?

[ayufan]

Ideally new images has to be built. It's somehow possible to patch existing installations.

I did load CEC kernel driver on Pine A64 linux.

Nice one! Perhaps you can help in getting this functionality implemented in a future OS build?

My Android HW driver does work. System does connect with TV. Trying now to see if I can control system from TV.

I also did manage to modify existing Android installation, instead of compiling the full fledged system. Still having a full system image seems to be better choice.

I can control my TV from Android. However, there's a big delay in controls, but it does work.
