RM57L843: RMII interface using KSZ8081RNA PHY

Part Number: RM57L843
Other Parts Discussed in Thread: HALCOGEN

Hi Team,

We are trying to establish a communication between RM57L483 and PC using ethernet over RMII.

We have written a driver for KSZ8081RNA PHY and able to read PHY ID and LINK STATUS successfully.

We have integrated KSZ8081RNA driver in the ethernet demo code.

In lwip_main.c initialize lwIP TCP/IP stack for the HDK EMAC using DHCP but lwIPInit always returning 0.

We have also tried with static IP but its not able to ping. 

We have configured pinmux for RMII in HALCOGEN.  

Is any other configuration required for RMII to get worked? Please suggest.

Thanks,

Aditya
