CPU Can't stop

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;
}

Start by tracing swd_wait_until_halted() and inspect how DBG_HCSR, S_HALT, and MAX_TIMEOUT are used when the target connects. Reproduce the failure with a target and verify whether the CPU reaches the halted state; the issue is resolved when the stop function reliably reports a halted CPU.
