Hello,

does anybody use the MicroSys IP360 Board togehter with SDS
SingleStep Debugger ?
What I'm particular interested in is the target initialisation,
because till now I was unable to configure it correctly.
I always get the message 'Unable to initailze stray/reset vector at [address]'
and 'Unable to set breakpoint at [address]'

Could anybody help

Thanks in advance

I believe that the SDS debugger manipulates the contents of the
location pointed at by the VBR for it's breakpoint control at VBR +
32(??). These are vectors not hard addresses. Also, I believe that the
breakpoint addresses have to be in ram not rom.

So - for the first error message, I believe that you have to do two
things, first include the reserved debug vector in the sstep.ini file, I
believe that it is vector 32. Also, the VBR must be in RAM so the
debugger can modify it.

Second - If the debugger was unable to claim the vector that it needed in
step one, you will not be able to set break points. Also, I believe that
the breakpoints must be for code located in Ram, not rom.


Good luck.

Sorry for being vague, I'm out of the office and I can't check these
things out for accuracy.
