Start to using adv7282 chip.
Have no ACK on I2C bus. RESET and PWRDWN controled from FPGA. Tryed any combinations, no result.
What waltage shoud be on VREFP and VREFN pins?
1) Is the exposed metal pad connected to ground?
2) Do you have any other I2C devices to verify the FPGA is working correctly
3) We use 8-bit I2C instead of 7-bit addressing, requires bit shifting to match up. Check that the driver is outputting the right address or sweep all possible addresses to see if it responds.
Solved. It was adv7282M chip instead of adv7282
