Hello,

 

Regarding ADV3002 SRAM, I  have questions.

 

I tried to write/read EDID to ADV3002 EDID SRAM on ADV3002 eval board by using ADV3002 Evaluation Software (v0.4).

EDID data is ADV3002_ES2.edid.

 

I operated the following method written in ADV3002 Eval Kit Reference v2.0 (ADV3002_Eval_Reference.pdf)

 

Page 8 - Page 10

8 Using the ADV3002 Control Software to program the System EEPROM

 

As the result,

Write EDID failed? success?

  Log on ADV3002 Evaluation Software (v0.4)

     EDID : WRITE TO EEPROM DONE (part 2/2)

    0EDID : WRITE TO SRAM DONE (part 1/2)

 

Read EDID may be failed.

  Log on ADV3002 Evaluation Software (v0.4)

    ADDR: 0x 0 DATA: 0xFFF 0xFFF 0xFFF 0xFFF 0xFFF 0xFFF 0xFFF 0xFFF 0xFFF 0xFFF 0xFFF 0xFFF 0xFFF 0xFFF 0xFFF 0xFFF

 

Please teach me the solution of this issue.

 

Best regards,

Hodaka
