Occasional ContributorI want to test some Ethercat IP:s on a DE10 Nano board and need two Ethernet interfaces. I would like to use the one already on the board but it seems it only interfaces through the HDS.
I will add an extra PHY board for the other port but if I can't use the KSZ9031RN PHY directly I think I will need to add two extra ports.
Regular ContributorHi PYtte,
Unfortunately the answer is no. I checked Terasic DE10 nano board user guide doc page 37 and it mentioned on board Micrel PHY chip is connected to Cyclone V FPGA HPS Ethernet MAC block.
So, you need to use HPS Ethernet MAC to interact with this on board PHY chip and not regular FPGA soft TSE IP to talk to the PHY chip.
Thanks.

Occasional ContributorOk thank you for your response. I was hoping it was using some of the pins that could be loaned to the FPGA.
I will have to add a PHY externally then to connect to GPIO for the FPGA.
