One of our local customers has purchased and is using an Avnet FMC card (AES-FMC-HDMI-CAM-G) with a ZCU102 board. They are using it with one of Xilinx' base TRD designs for the ZCU102 board that targets this Avnet board.
With the board plugged into the ZCU102 FMC connector it’s pulling an adjustable voltage supply down.
According to the TRD on the ZCU102 it’s set to 1.8V, but when the Avnet card is plugged in it is being pulled down to 1.174V. All of the devices the voltage goes to support VCC of at least 1.8-3.3V (some support 1.2 or 1.5-3.3V).
Has anyone used this board combination and is able to help along these lines?

Looks like the customer was able to correct the problem using information from the Xilinx wiki.
Here are the details just for sake of completion on this thread:
On the base TRD design GUI, they were getting “FMC not connected” error displayed.
The “normal” sequence to set an FMC card VADJ voltage is to insert the FMC card, turn on the development board, then set the VADJ voltage. However this didn’t work.
On the MPSoC base TRD wiki site (see link below) the process to correct this error (set VADJ voltage) is different.
You first power up the ZCU102 without the FMC card installed.
Set VADJ to 0.0V.
Plug the FMC card into HPC0.
Set VADJ to 1.8V.
Press POR_B to reset/restart the FPGA.
HDMI input is not working, GUI displays error message
FMC not connected
