I have a custom Arria 10 SoC board with a Marvell 88E1512 PHY attached to the HPS EMAC0 that I'm trying to get working with Linux. The kernel boots and upon running dhcp (or ping with a static IP) - there are 0 RX Bytes reported. I can see my ping or dhcp request from wireshark, so I am indeed transmitting just fine. But I can't receive. I have looked at the signals on the PCB, and all signals appear to be working (i.e.: I can see the activity when I ping, etc.). Has anyone implemented a PCB with an A10 + Marvell PHY? Any ideas what could be the issue? Maybe an issue in the device tree source?
Thanks, JohnLink Copied

Hi John,
I use Cyclone V and 88E1512, and find the same issue as you. Have you fixed this Rx issue? BR Simon
