Hi,
I have found the reason that coldfire dropped into exception. It is because of the timer. I commented the timer codes and the exception never happened again. Can anybody who had experience with coldfire dBUG told me why？ Thanks! _____ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Will Huang Sent: Tuesday, July 03, 2007 2:30 PM To: uclinux-dev@uclinux.org Subject: [uClinux-dev] Coldfire dBUG problem 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.
