Power on AD-FMCOMMS2-EBZ from ZC702

After debugging it looks like the power rail for the xcvr chip (ad9361)on the eval board is not getting the power good signal (PG-FMC) from the ZC702 board (should be asserted highand it’s not). As a result there’s no power going to the ad9361. And we get thefollowing error upon boot:

I followed the directions on the ADI wiki page to create the SD card with the Xilinx image and moved the ad9361 boot.bin and devicetree to the main boot partition. The Xilinx board does see the eval board and the AD7291BCPZ, and can even read it’s voltages but not the ad9361.


Is there a step I’m missing to turn on the 1.3V and 1.8V supplies for the AD9361?
