Something pertaining to ADV7510

Hi~ all:

        I am using AD7511 now. But I came up against some problems.

        The following is my configuration for AD7510. Please tell where I did wrong.

        I can't see any picture or color bar on the TV screen.

        Status: No enable HDCP, no enable all the packet functionalities, is able to got the HPD and read EDID.

        and sent 1280_720p_60HZ video format to AD7510 via video capature interface. The video content is 0x4040 (always sent this value)

        it is sent from FPGA.

  • Hi~Dave:

            I know the TMDS has 4 differential pairs, and one of them is clock.

            However, I still can't see any clock drive out.

            The display I used can displays 1080i (Sony, BRAVIA), it can show

    video well with DVD player.

            I find the register 0x44 --> 0x79. Showing N_CTS, Audio smaple, AVI

    InfoFrame, Audio

            InfoFrame enable. Should I have to fill out Audio InfoFrame? I

    filled out the AVI InfoFrame,

            but still no picture pattern on my display.

            Actually, I followed the instruction of quick start in the "AD7510

    programming guide".

            to fill the value into individual registers it says. However,

    doesn't work. Do you have

            a clear initial procedure document or reference code? So that I can

    come out soon.

            BR
