Strong SRT 2401


#1

Hello,
I tested CE latest on Strong SRT 2401. It is S905D based, 1GB RAM, 8GB disk. It is D version of chipset, so box contains TV tuner - DVB T/T2,C,S. Standard SW is an Android with dumbAmlogic TV application.

I used https://github.com/LibreELEC/device-trees-amlogic/blob/master/gxl_p231_1g_dvb.dts as device tree image and CoreElec works at first try. For the tuner I tried all three options in CoreElec DVB drivers and for CrazyCat it almost worked - it was created folder /dev/dvb/ with some device files inside, but without any file named frontend0, or something similar. This is fragment of dmesg:

I believe it can be fixed with proper device tree. I have the device, so I am able to test anything repeatelly.

I want to ask - what information is required for create proper device tree? I will try to provide it. And - is there anybody, who will be so helpfull and create the device tree file?

I believe, this hardware is common in central Europe - here in Czech rep., in Germany, in Hungary. So I see it as good to have this device working on CoreElec (incl. TV tuner) and I am ready to donate the work in some small amount.

The Andriod TV is really dumb and ugly :slight_smile:
