This happens to me (on Cortex M3 / LPC1768) when I have Interrupts on, e.g. Timer. The Timer keeps running when the core is halted; When you hit "continue" it will first execute the interrupt vector and then returns to the instruction that has the breakpoint set, thus hitting it again. I can see this when I use the "step" command instead of "next". You might try switching off interrupts for code stepping. There is a "cortex_m3 maskisr on|off" command for Cortex M3 MCUs, I suspect there is something similar for other ARM CPUs. Hint: GDB can exectue scripts on stepping on/off. -- J.Fischer _______________________________________________ Openocd-development mailing list Openocd-development@lists.berlios.de https://lists.berlios.de/mailman/listinfo/openocd-development
