Dear Mitchell Burnett, Thank you for the help with this matter. The manufacturer of the optical transceiver is likely confused as to the nature of the RFSoC 4x2, justifiably. To make some progress with them, I would need a kind of utility for the 100Gbe port. Something which reads raw status and error codes from a transceiver plugged there ( or better yet, displays those codes in human-readable form.) I imagined that either AMD or their Xilinx division would have a utility for this that interops with the Linux processing system, in a manner independent of the FPGA. However, as you said, the 100Gbe port is connected exclusively through the FPGA fabric, if I understood correctly?
