Just got EVAL-AD9388A/ADV7441AFEZ_x + ATV MOTHERBOARD REV B + VIDEO OUTPUT BOARDS REV B from ADI.

Just like the http://www.analog.com/en/audiovideo-products/video-decoders/products/ev-documentation/CU_eb_EVAL-ATV/resources/fca.html

I installed the SW and run ADV REGISTER CONTROL 4.13J. But SW always report I2C error when load script.

I measured the test points on ATV motherboard T20 and T21, which are SCL and SDA. They are always high, no action at all when I try to read/write I2C bus. Also Check the LPT port is "378", no problem.

My Widows XP can find the USB device on ATV board and D8 light "ON". FPGA on ATV motherboard is correctly loaded up and all LEDs are"ON".

I even programed the FPGA PROM again. But still have same problem.

Is the ATV motherboard broken? How can I do to fix the problem.

Regards,
