Hi guys,

Now I want to add AT070TN83 LCD panel with my BB black.

The detail of my board is as following:

kernel: 3.2.0

filesystem: arogo

LCD panel: AT070TN83

I have modified the driver with da18xxx.c and board_am335x.c.But, when I start the board, the print information says:

"Error opening /dev/fb0: No such device" and "LCDL not supported on the evm (6)"

What should I do ?

Chancen,

Have you ever checked out our linux board port lab? It might be really helpful to you here. It has some steps that show how to add LCD support for the 7 inch LCD we use on our General Purpose EVM, and it also works for the LCD7 for BeagleBone.

That should be a good place to start--hopefully if you adjust the parameters to reflect those of your LCD screen you can get things working.

Regards,

Josh
