Part Number: TDA4VM
Hi TI Team,
I am running the enet_lwip_example code on mcu1.0 side, Here I am not getting the IP address on my custom board but in TDA4 EVM I got the IP address.
Differences between EVM and custom board:
EVM : we have MCU Ethernet with PHY (DP83867ERGZT)
Custom board : we don't have PHY in custom board, here we are using external loopback between cpsw9(mcu2.0) and cpsw2(mcu1.0).
Whatever I am running the example on EVM, same example I ran in custom board with few modifications. I made a PHY-less changes in my code, In main.c, we have this function EnetApp_initLinkArgs(). In this function below 3 lines I modified.
EVM code:
phyCfg->phyAddr = boardPhyCfg->phyAddr;
linkCfg->speed = ENET_SPEED_AUTO;
linkCfg ->duplexity = ENET_DUPLEX_AUTO;
Custom board code changes:
phyCfg->phyAddr = ENETPHY_INVALID_PHYADDR;
linkCfg->speed = ENET_SPEED_1GBIT;
linkCfg ->duplexity = ENET_DUPLEX_FULL;
Please find the below output logs both EVM and custom board.

On custom board It is going continuously. Can you please help me to resolve this issue.
