Hello expert

 

eval-adv7612-7511 not work with some HDMI monitor

My question is:

  1. how about the firmware of ADSP-BF524 control flow.(configured register of ADV7511/ADV7612)
  2. Can you give us full address setting for ADV7511/ADV7612.(the recommended script in AVES soft is part address setting)

The work mode1 is: 720p@60,video port use RGB, audio 2 channels i2s.

The work mode2 is: 720p@60,video port use RGB, audio 8 channels i2s.

 

Issue description

  1. It seems the firmware on ADSP-BF524 will auto setting ADV7511/ADV7612 base on
  2. Input video resolution to ADV7612
  3. Input audio sample rate to ADV7612.

The reason is: N of ADV7511 setting different value.

  1. EDID of hdmi monitor connect to ADV7511

The reason is: HDMI/DVI mode of ADV7511 configure on different hdmi monitor.

The reason is: i2s0~3 enable configure on different hdmi monitor.

  1. HPD of hdmi monitor connect to ADV7511

So how about the firmware control flow.

 

  1. (HDMI Tx)ADV7511 connect to 3 type monitor work ok(asus, philips, etc ).

But there is not display on the hdmi analyzer(astro va-1809). The analyzer seems no video data input.

my puzzle is: is there some error in my setting on ADV7511?(the setting is attached)

Can you give us full ADV7511/ADV7612 setting.

The work mode is: 720p@60,video port use RGB, audio 2 channels i2s.

The work mode is: 720p@60,video port use RGB, audio 8 channels i2s.
