Hi,

 

I am using ADV7619 card. These are the settings I am using for the hdmi rx

 

-98 F4 80 ; CEC
-98 F5 7C ; INFOFRAME
-98 F8 4C ; DPLL
-98 F9 64 ; KSV
-98 FA 6C ; EDID
-98 FB 68 ; HDMI
-98 FD 44 ; CP
-44 6C 00 ; CP Clamp disable
-68 C0 03 ; ADI Recommended writes
-68 03 98 ; Set DIS_I2S_ZERO_COMR 0x03[7]=1
-68 10 A5 ; ADI Recommended audio writes

-68 4F 08 ; ADI recommended writes
-68 50 C0 ; ADI recommended writes
-68 57 A3 ; ADI recommended writes
-68 58 07 ; ADI recommended writes
-68 93 03 ; ADI recommended writes
-68 5A 80 ; ADI recommended writes
-98 01 06
-98 02 F7
-98 03 42
-98 0c 42
-98 15 80
-68 00 08
-68 02 03
-68 01 03 // Enable clock termination
-44 ba 01 //Enable free run mode
-98 74 00    

 

Edid programming

-64 77 00
-//256 byte edid data
-64 52 20
-64 53 00
-64 70 9E
-64 74 03 // enable edid

 

 

When I connect a hdmi transmitter to the adv7619 input , it is always running in free run mode. Host is not detecting the hdmi rx.

HPA is enabled , cable is detected (read back register values), edid map is programmed correctly with the edid data. I am able to read back the edid properly. Is there something wrong i am doing here??
