Hi all,
I am not sure if it is proper to ask such a question in this maillist. But I am really confused with this problem.
When I download kernel image from TFTP by using dBUG, my M5272C3 board drop into exeption. I have googled for answer and find someone has met this kind of problem(attached below).
From his description, I learnd that he has solved the problem but I do not understand his words.
So, can anybody give me some advice on his word, "I had a similar issue on my 5275 and it went away after I added a
significant for loop before I initialized the ram"?
Thanks a lot!!

Hi all,
I'm testing uclinux: I downloaded uClinux-dist-20051110.tar.bz2,
and compiled with default options (kernel 2.4, board Motorola,
processor M5282), gettig a file image.elf.
The procedure didn't give any error and compile correctly.
Now I'm trying to download to the M5282EVB evaluation board,
where I have dBUG:
ColdFire MCF5282 on the M5282EVB
Firmware v3b.1a.1b (Build 6 on Jul 01 2003 11:32:29)
Copyright 1995-2003 Motorola, Inc. All Rights Reserved.
when I try lo load the image I get:
dBUG> dn -e uclinuximage.elf
Ethernet Address is 00:CF:52:82:CF:01
