Hi, Can anyone explain why debugger may be crashing?

 

Single stepping over CODE-A crashed the debugger requiring a power reset of USB blaster, sof download and restart eclipse.

 

Running over CODE-A works ok.

 

 

[CODE-A]:

for (int i=0; i < MAX_INPUT_STRING; ++i) e->cmd[i] = me->m_cmdString[i];

Hard to say. What options did you use when compiling? Compiling with anything other than -O0 could cause weird debug stuff to happen. How are "me" and "e" declared?
