DS90UB949-Q1EVM: Loading EDID data from local EEPROM

Hi TI，

    We are using DS90UB949 evm ，and we want to use external EEPROM of 949 EVM side to provide EDID. The MODE_SELx Settings are as below:

    MODE_SEL0=5, MODE_SEL1=1

    EDID_SEL: 1

    AUX_I2S:0

    EXT_CTL:0

    COAX: 0

    REM_EDID_LOAD: 0

    The EEPROM part number  is AT24C256, We change the EDID in EEPROM,  but the EDID is default value of internal SRAM.  Could you help me to solve this problem?

Hi Lingying,

The English Forum engineer has replied:

Can you double check the MODE_SEL settings?

I see the REM_EDID_LOAD is listed as '0'. As per the user guide, it should be a value of '1'.
