We use ADV7612 and 7511 as the RX-TX pair on our custom board.
We have no problem playing non-encrypted 1080p content, but with encrypted content at 1080p60, the video flashes and there is noise on some portions of the video. The authentication seems to happen fine but then video starts flashing soon after.
Sometimes, we see bad BKSV error or HDCP unknown error interrupts on the TX side.Because of this, I think the authentication process restarts, but sees the error, restarts, and this keeps happening.
Has anybody seen this or know why this happens?
I run this program via Xilinx SDK. One weird thing is that when I stop the execution, the video appears fine.
