Part Number: DRA76P

 Hello Mde/Mrs

I am working on a custom board based on DRA76p , I already developed a  vision application rvc using the use case vip_single_rvc_cam_view_crc  for the ti evm baord jacinto6 witch based on dra74 and the display was on the LCD "the screen on the board" , so now  we switched to our custom board described before , I did every changes and applied the patches for this UC mentioned on the Robust_RVC-5.0_Phase-6_Release_Note.pdf , also changed the dts files and using dra76-evm-robust-rvc.dtb . but without any things can be appeared on the HDMI even in the bootloader stage !  i attached the dts files bellow .

Regards

    Hi Ahmed,

    Can you clarify the issue for me? Is the RVC displaying on the HDMI without the changes, or is it not coming up at all after your changes for your board?

    Thanks,

    David
