[U-Boot-Users] Ethernet does not work on at91rm9200

hi hamid,
i added CONFIG_AT91C_USE_RMII to my configuration and now it works. 

sorry guys for trouble i caused!

another problem i have is that if i boot via nfs everything works, linux
knows the mac-adress. 

but if i boot from filesystem (jffs2) than linux doesnt know the mac-adress.
if i stop at u-boot prompt, call any network function, and start linux
afterwords, then linux knows the mac-adress. 

does u-boot only initialize the ethernet interface if it is needed? can i
force u-boot to init the ethernet interface or is there another 'standard'
way to tell linux the mac-adress?

Hi Peter,

The ethernet works fine on at91rm9200dk board. Can you give more information
about this issue? (hardware differences with at91rm9200dk board (PHY MII or

our custom board runs now perfectly with u-boot 1.1.1 except that the
ethernet is not working. But the ethernet worked when we used u-boot 0.4.0.

Changing only the driver file at91rm9200_ether.c, now using the u-boot 0.4.0
driver file version in u-boot 1.1.1 helped to fix this problem.
