[U-Boot-Users] problem with 'ethaddr' env. variable in, DataFlash, at91rm9200dk

[Aras Vaichas]

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

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

Any help would be good, thank you!

This is NOT a valid MAC Address. Don't do this, not even for testing.

See http://www.denx.de/twiki/bin/view/DULG/EthernetDoesNotWork and

Does this problem persist even after a reset of the board?

> Any help would be good, thank you!

Check if the at91rm9200dk port  initializes  bd->bi_enetaddr  or,  if
it should be using CONFIG_NET_MULTI, eth_get_dev()->enetaddr ...

yes

It looks like gd and bd are being set up wrongly or are being "lost" somewhere.

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

U-Boot 1.1.1 (Aug 17 2004 - 16:39:28)

U-Boot code: 21F00000 -> 21F14A88  BSS: -> 21F18F2C
RAM Configuration:
Bank #0: 00000000  0 kB
... snip ...
### main_loop entered: bootdelay=3

### main_loop: bootcmd="<UNDEFINED>"
Uboot> setenv ethaddr c2:65:66:f4:14:3e

gd = 00000000, bd = ffffffdc
Uboot> dhcp

at91rm9200_ether.c bd->bi_enetaddr = 0:0:0:0:0:0
*** ERROR: `ethaddr' not set
Uboot>
