one tick has us 1000
delay 1000ns ticks_cnt 1000
is rtems_counter_nanoseconds_to_
ok, thanks! i have read it, then im not sure CPU_Counter_ticks is system
tick ?

https://docs.rtems.org/branches/master/c-user/configuring_a_system.html#configure-microseconds-p

a 21ms counter in fact more than 10s, see log , my rtc 10s wake up
static void Delay_ms(x)
{

int int_num = 0;
if(x % 10 == 0)

int_num = x / 10;

else
{
int_num = x / 10 + 1;
