I am using the AD9889B on for a project. I have previously been able to make
this work but I am having problems now and cannot repeat my results. I am
trying to set 0x41 to ‘0’ to power up. When I plug in the HDMI cable,
register 0x41 goes from 0x0 to 0x60 which means HPD and Rx term detect. After
that I read 0x41 and it is 0x50. I then try to write 0x41 to 0x10 and it
always reads back 0x50.
Do you have any other debug suggestions?
