@Ian Goodacre mainline kernel should already have support for the onboard gmac Ethernet port? If you had issue with Ethernet using an unmodified kernel device tree, please try again after your U-Boot update. The Ethernet port was working fine in both U-Boot and kernel when I added support for the NanoPi R2S Plus to U-Boot.

Support for NanoPi R2S Plus was added in U-Boot v2025.01. Suggest you update U-Boot from v2022.07 to v2025.01.

There should only be an issue when someone use boot firmware intended for a different board. Please read the patch thread, the patch was partially rejected. If you want to do a custom patch just replace ethernet-phy-ieee802.3-c22 with ethernet-phy-id001c.c916 in Linux device tree.

As I stated in a reply in that patch thread, those changes are not fully necessary. Boot your ROCK 3B with mainline U-Boot built for the ROCK 3B and ethernet on mainline Linux should work. Use ROCK 3A or 3C boot firmware and you will have i.e. ethernet phy issue on mainline Linux.
