Hi I'm learning cortex m4 debug feature,
I'm using stm32f407 discovery with openocd in ubuntu
I'm trying to understad breakpoint feature,
I can set breakpoint address in openocd and chip will stop when pc run to that address
like main function is at 0x8008000,
I guess there must be a register to store this address(0x8008000), but I cannot find wher is this register from all information I can get
can anyone tell me where to learn relative info, thanks :)
