I used the adv7612 as HDMI receiver and used the adv7511 as HDMI transmitter.
I had to re-plug (unplug and plug ) the input video cable from the input video source every time, then
I can see a correct video in my display. It's annoying, and I don't know how to fix it.
Can anyone kindly answer the problem?
I checked the register. When the adv7612 power up, the 5V for port can be detected, the clock of input video
can not be detected or locked. I unplug the input cable from HDMI source and re-plug it, it works well.
adv7612 as HDMI receiver
adv7511 as HDMI transmitter
input source from Intel graphics 4600 HDMI output port 1920x1080@60
I tried to resolve the problem as follow:
1. power down 7612 HDMI chip (0x0C) and power up ---------- doesn't work
2. power down CP core, DPP and digital section of the hdmi core and power up --------- doesn't work
3. set the tristate output and untristate ---------- doesn't work
