Hi !

 

I have some question about ADV7480

 

************************************************************************************************

Q1)

I was reading ADV7480's required setting.

At the setting file , it says it supports720p @ 60

Is there any file to support 1080p @ 60?

************************************************************************************************

Q2)

The "required setting" is for general.

Not only for EVAL-Board .

Is my understanding correct?

Q3)

To write EDID

  ①IO MAP Address 0xF6

      => 0x68
  ②HDMI RX Repeater Map Address 0x70[7:4] primary_edid_size[3:0]
   =>0010:256byte
  ③HDMI RX Repeater Map Address 0x7A[6:4] edid_segment_pointer[2:0]
   =>000:First 256 bytes of EDID data area
  ④HDMI RX Repeater Map Address 0x7D[0] dual_edid_enable_port_a
   =>0:Primary EDID data area

  ⑤EDID MAP Address 0x00-0xFF

      =>Write EDID

This is the procedure.

Is my understanding correct?

Is there any register setting to add this?

Q4)

To use HPA automatically

  HDMI RX Map, Address 0x6C[2:1] hpa_auto_int_edid[1:0]
     =>10:EDID & when ADV7480 detect the HDMI cable connected , HPA will work
  ②HDMI RX Map, Address 0x6C[0] hpa_manual
 =>0:HPA takes its value based on HPA_AUTO_INT_EDID

Is there any register setting to add this?

Best regards
