Axiom mcf5235BCC freezing

[Alan Cudmore]

Thad,
I use these boards extensively and have no problems with RTEMS  
freezing. I often leave one running in my office for days, if not  
weeks and it seems stable.

I have used RTEMS 4.9.x, but I'm up to a fairly recent CVS version  
right now with the 4.10 tools.

Somewhere in the 4.9.x release there was a problem with the code in  
start.S on that board. Compare the code in libbsp/m68k/mcf5235/start/ 
start.S between your version and the latest CVS version.
I'm pretty sure this was added:

     move.l  #0x20000201, d0
     move.l   d0,(0x40000008)        | set up 2nd RAMBAR to make 2nd  
port avail to FEC

Otherwise, I cannot think of anything else that freezes the board. Do  
you have a second board to try?

Also, I have not loaded via TFTP. I use BDM most of the time, then I  
also have a modified flash build of RTEMS that I load in place of the  
monitor that comes on the board.

Alan
