[U-Boot-Users] MPC875 & FEC Ethernet

[Josef Angermeier]

Hello

I can use the u-boot command interpreter on my MPC875 board. FEC1 is
responsible for ethernet. So i set in my board config file:

#define  CONFIG_ETHER_ON_FEC1
#define CONFIG_FEC_ENET
#ifdef CONFIG_FEC_ENET
#define CF_DISCOVER_PHY
#define FEC_ENET
#endif

when i call "ping target", i get the message "TX timeout". According the
the debug output FEC1 just doesn't fetch data from the TX buffer, though
ECNTRL and X_DES_ACTIVE set correctly. Any ideas how to solve this ?

big thanks

josef

Check your clocks / clock routing / pin configuration.
