here are parts of my configuration


   /*config HPA takes its value from HPA_MAN_VALUE_X */ { ADV7611_I2CADDR_HDMI, 0x6C, 0xA7 },
   /*delay 100us*/ {ADV7611_I2CADDR_DELAY,0x0,100},
   /*config 0v to HPA pin, but it's not working!!!!*/ {ADV7611_I2CADDR_EDID,0x20,0x70},
  /* delay a while to make HDMI source worked*/ {ADV7611_I2CADDR_DELAY,0x0,1000},
/* config high level of HPA pin.*/    {ADV7611_I2CADDR_EDID,0x20,0xF0},


according to the datasheet name <ADV7611_Software_Manual_pr0.pdf> .the red line ought to change HPA pin to 0 v.and then the HDMI souce would read EDID......


but the red line is not working. the HPA pin is in high level all the time.


anyone can help me? I really appreciate
