Enable Panel LCD on R40 AllWinner???

Recommended Posts

I can compile the kernel 4.14 for H3 , modify the device tree and then put this to my bananapi M2 ultra with R40 Core and can enable the HDMI connector success.  I get an image on the screen on my monitor.

But now I can enable the LCD (RGB pinouts port H) to get image on my display 7" but I do not know how to do on the device tree file to enable a PANEL or something more . Someone have a device tree file that have enable the LCD (RGB ouput) to take an example to know how to do that because on the web almost all the people usually use the hdmi connector.


Thanks at all ...


PD: I get success on R40 to modify the SPI, smartcard, ethernet drivers and have an Ubuntu 16.4 running (desktop) on the Bananapi M2 Ultra. Then I will explain how to do that.
