CPU Can't stop

[ssyqwer]

HELLO !

When I connect the target, the cpu is still working, and I want to stop the cpu. This function cannot be realized.

I hope you can help me.

static uint8_t swd_wait_until_halted(void)
{
// Wait for target to stop
uint32_t val, i, timeout = MAX_TIMEOUT;

for (i = 0; i < timeout; i++) {

    if (!swd_read_word(DBG_HCSR, &val)) {
        return 0;
    }				
    if (val & S_HALT) {
        return 1;
    }
			
}

return 0;

}

I used your code to make an offline programming device, and the code debugging card is here.
