Ken, The 100 GbE ethernet is not a processing system attached core in the typical sense like your NIC on your servers. These are connected directly to the fabric of the FPGA and are polled using their memory map register.
The 100 GbE is covered in tutorial 4 for the RFSoC tutorials. More is also shown near the end for accessing those memory mapped registers and configurations via casperfpga. Sorry you are having transceiver issues on the FPGA side. That tutorial also shows some recommendations on transceivers and configurations. However, you most likely are needing to toggle the module reset pin. This is again done using casperfpga by adjusting the according GPIO yellow block from the example design. https://casper-toolflow.readthedocs.io/projects/tutorials/en/latest/tutorials/rfsoc/tut_100g.html Mitch > On Jun 6, 2023, at 9:11 PM, Ken Semanov <shapkiqua...@gmail.com> wrote: > > board = Zynq UltraScale+ RFSoC4x2board (Gen 3 ZU48DR) > I am in contact with a manufacturer of 100Gbe optical transceivers.
