Greetings,
sir/Madam the hardware break points use internal FPB comparators so that the address we update there are internally comare with program counter if value == program counter then automatically the core will be halted and ready to debug the internal registers.
coming to the software break point this will use "BKPT" instrruction so that when ever the address match with program counter user has to execute __ASM("BKPT"); which will case the target break and enter into halt so that user can further access the debug registers.
my doubt was how should i continuously check the program counter continuously so that i could break the target when ever address i supplied was match.
Correct me if i was wrong.
Thanks and Regards.
Harshan.
Thanks for Reply,
In Hardware Break Point after setting the first break point the core was halted successfully but when i tried to run the target it won't hit the second break point until i clear the first break point. what might be the issue??
