Hi,
I have a ZedBoard and would like to use the default Ethernet "Jack" (+PHY etc.) which is already on the board. However, I would like to use this jack with one of the alternative Ethernet cores (in PL) rather than the default GEM0 (in PS).
I want to do this because I would like to support Jumbo frames but also offload some work to the PL, which is really tricky to do with the GEM0 since it is so closely tied to the PS.
Is this at all possible? I would imagine I simply need to route the RGMII signals from the Ethernet PHY not into the FPGA PS but into the FPGA PL. How would I do this? When I use Vivado, by default, these signals get routed into the PS7. I'm relatively new to Vivado.
Thanks!
Best,
Jan
