Subject: [U-Boot-Users] problem with 'ethaddr' env. variable in, DataFlash, at91rm9200dk
Message-ID: <41203DC8.1000108@magellan-technology.com>

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
ESC[2J

Set PLLA to 180Mhz and Master clock to 60Mhz and start U-BOOT?

Any help would be good, thank you!
