This is a random address which  happens  to  be  not  mapped  in  the
specific  board  (MPC8260ADS.h).  The approach taken here is strongly
deprecated - it is juat an examp[le of a badly maintained board.  In-
stead, I recommend to use an addrress which causes a checkstop on all
boards,  idependently of the cspecific memory map. This is what we do
here:

In the end, the effect is the same.

And I have no idea why it would not work  on  your  board.  Attach  a
debugger and find out where exactly the code is hanging.

Ummm... and if you run under a debugger, *detach*  it  and  check  if
reset starts to work...

Best regards,

Wolfgang Denk

It's certainly  convenient  the  way  the  crime  (or  condition)  of
stupidity   carries   with   it  its  own  punishment,  automatically
admisistered without remorse, pity, or prejudice. :-)
