Hi there,

 

We're using the EVAL-ADV7625-SMZ eval board with AVES3 and the ADV7625 script file that is available at http://ez.analog.com/docs/DOC-10766.  When we boot up the board normally (no jumper from J15.1 to J15.2), we get HDMI video and audio going through from RXA to TXA.  When we boot with the jumper across J15.1 & J15.2, and use AVES3 to download scripts that SHOULD still pass video from RXA to TXA, we don't get any video output on TXA.  The scripts we've tested are:

 

:01-01 Mux Mode - RXA-TXA, RXB-TXB:

 

:03-01 Audio - RxA-AP1_OUT, RxB-AP2_OUT, Video - RxA-TxA, RxB-TxB:

 

:03-02 Audio - RxA-AP1_OUT, RxB-AP2_OUT, Video Splitter Mode - RxA-TxA & TxB:

 

Once we run the scripts, the video no longer passes from RXA to TXA, and unplugging both HDMI source and destination and plugging them back in doesn't help.  When we run the 03-01 or 03-02 scripts, the AP1_OUT audio extraction starts, but we're getting a crazy high sample rate of ~316.4kHz.  The AP1_OUT_SCLK and AP1_OUT_MCLK are ~20.25MHz and ~40.5MHz respectively, which are 64xfs and 128xfs.  The HDMI input into RXA is outputting 44.1kHz sample rate according to the RS232 monitor, so not sure what's going on here. 

 

Is there something we're missing?  We can't find anything in the User Guide for the EVAL-ADV7625-SMZ that we're doing incorrectly.

 

Best regards,

Kent
