ADV7619 chip not transfer

Hello I make custom Board and use ADV7619 HDMI Rx chip

Now EDID OK.

Because Moninfo detect Board 

But 

Chip Output Pin (P[0] ~ P[48], Vsync, Hsycn, DE)

why not trasnfer???

I set freerun mode , then  data, vsync, hsync, DE pin swing

I thank internal pattern generation,

I want to take TMDS.

Our system

PC -> CustomBoard(ADV7619) 

Please your Script ...

    Hi

          Please use this script 2047.ADV7619-VER.1.9c.zip based upon your input resolution.

          Register configuration related manuals are available at https://ez.analog.com/video/w/documents/773/adv7619-design-support-files

    Thanks,

    Poornima

  • I test your scrip below.........

    that is not operation

    did you test your script???

    because my script 

    1. windows detect OK

    2. TMDS transfer OK at HDMI cable

    3. ADV7611 not trasnfer data signals.

    bur your script 

    1. windows detect NO

    2. TMDS transfer NO at HDMI cable

    3. ADV7611 not trasnfer data signals.

    why your script windows not detect???

    your script doc write????

    Hi,

     You might have not written the EDID with respect to map address 0x6C, These writes are available in the 1817.ADV7611-VER.3.0c.txt.zip

    Please note PC generally do not work unless they see a valid EDID &  PC will only recognize a sink only when they detect an valid EDID .

    Refer below thread for EDID initialization script,
    https://ez.analog.com/message/31879#31879

    Instead of PC as an source could you please check with other sources like generator and let us know the result.

    Please make sure the crystal pins are oscillating at the right  frequency (i.e 28.6363 MHZ) ?
    Also make sure with below HDMI frontend locking status registers to check whether input device is correctly recognized.                    
              a) Registers HDMI 0x04, 0x07, 0x1B, 0xE0
              b) Registers IO 0x6A, 0x6B
              c) And also signals on the VS, HS and DE pins.

    Thanks,

    Poornima
