Hey,
In the description of target_resume() is "int current" the value for the
current program counter.
How is this current program counter actually retrieved?
Is it handled in openOCD server?
Is it handled in openOCD Client?
if in Server, where is it stored, where to put the address of the program
counter?
Also if I use a debugger, load elf into it, halt the cpu, how actually does the
client know where execution has stopped?
A hint would be awesome ;).
thx Xense
target.c:588:
-------------
* @param current True to use the target's saved program counter instead
* of the address parameter
* @param address Optionally used as the program counter.
* ...
