MCU: LPC4333
Harware is custom.
I'm trying to get my DP83848 ethernet phy to work in RMII mode based on the lwip_tcpecho example.
The link status is good and the PHY_LINK_CONNECTED bit is set.
lpc_low_level_input() returns NULL because the descriptor is still owned by DMA
So no packets get received.
Has anyone else had similar issues ?

Resolved!
RMII mode only works when ENET_RX_DV mode is used
