Hello,
I've got U-boot 0.2.0 up-and-running on my MBX860 board (a entry-level
50MHz version).
This board, hoever, does not have NVRAM (there is no battery).
Will this be a problem, even if I hard-code all variables I need into
U-boot?
I'm trying to boot a linux kernel, but after the kernel uncompresses,
the board reboots:
=> tftpboot 200000 uImage
ARP broadcast 1
TFTP from server 10.0.0.150; our IP address is 10.0.0.200

Here's the environment I hard-coded into u-boot:

ipaddr=10.0.0.200
ethaddr=08:00:3e:2f:99:7e
stdin=serial
stdout=serial
stderr=serial
I'm using a unmodified version of the MBX configs for the kernel, the
from the Denx site
(ftp://ftp.denx.de/pub/LinuxPPC/usr/src/linux-2.4.4-2002-10-06.tar.bz2)
with no patches.
If the NVRAM is not the issue, does anyone have a suggestion? I haven't
the time to build me a debugger :-((
thanks,
RJ
