My problem is that the network functions do not seem to pick up the environment
variables "ethaddr" and "ipaddr".
e.g.
Uboot> setenv ethaddr 12:34:56:78:99:aa
Uboot> dhcp
*** ERROR: `ethaddr' not set
Uboot> echo $(ethaddr)
12:34:56:78:99:aa
Uboot> printenv
stdin=serial
stdout=serial
stderr=serial
ethaddr=12:34:56:78:99:aa
Environment size: 67/8188 bytes
Uboot> dhcp
*** ERROR: `ethaddr' not set
Uboot>
I've been going through the u-boot source code looking for where this problem
could be occurring, but I can't find anything.
I recently setup my at91rm9200dk to boot from DataFlash as per the Atmel
application note: "Booting u-boot from Atmel SPI Serial DataFlash on the
AT91RM9200-DK Board"
I used u-boot-1.1.1 instead of patching u-boot-1.0.0.
I've set the environment configuration values in at91rm9200dk.h
#define CFG_ENV_IS_IN_DATAFLASH
#define CONFIG_ENV_OVERWRITE
The system boots from the DataFlash OK, and then starts up u-boot-1.1.1
e.g.
-I- AT91F_LowLevelInit(): Debug channel initialized

Any help would be good, thank you!
