I have updated the my configuration for the CONFIG_ETHADDR and CONFIG_IPADDR But still getting same "TX timeout" error. from function static int fec_send(struct eth_device* dev, volatile void *packet, int length) in defined in the cpu/mpc8xx/fec.c

When I am running VxWorks on the same board LEDs at RJ45 connector (Ethernet interfaces) on the board are glowing but when u-boot is up these LED are off. It seems that ETH interface is not up yet.
Perhaps, your Ethernet driver is not properly configured. Recheck these definitions in your include/configs/tc870.h file:
#define CONFIG_NET_MULTI 1 /* the only way to get the FEC in */ #define FEC_ENET 1 /* eth.c needs it that way... */ #define CONFIG_FEC_ENET 1 #undef CFG_DISCOVER_PHY #define CONFIG_MII 1 #define CONFIG_RMII 1 /* use RMII interface */
I would pay special attention to CFG_DISCOVER_PHY. Maybe the wrong Phy is being configured?
Which board can be used as the reference board for the MPC870.
Maybe someone with experience with Ethernet on the MPC870 can answer?
I don't have a tc870 board or an MPC870, so this is the last time you'll hear from me on this topic.
Good luck!
Sincerely,
