I'm working on a design in which we'll use two FMCOMMS3 boards on the Zynq zc706 eval board -- one FMCOMMS3 is attached to the HPC FMC and the other to the LPC FMC. It seems like this configuration would be very similar to that used with the FMCOMMS5 board, however just using the FMCOMMS5 example PL design (and associated device tree) doesn't seem to work, as I get errors about "Unsupported PRODUCT_ID 0xFF" during Linux boot.
Has anyone tried running with two FMCOMMS3 (or FMCOMMS2, for that matter) boards attached to both FMC sites on the zc706? Any idea what the difference between that and the FMCOMMS5 configuration would be?
Thanks in advance.
