In a recent release (not sure which one) the option to select USER_PHY was added to the platform settings under LWIP.
I need to implement a different PHY for a LAN9374. It is basically identical to the LAN8742. The only issue is that the LAN8742 init code fails unless modified slightly. If I select LAN8742 and modify the file I can get it working but as expected every time I regenerate the project the modifications get overwritten. Where is the documentation on how to implement a USER_PHY?
