rtems_task_wake_after

[Fabio Degiovanni - Eicas]

Dear Sirs,
                I'm new with RTEMS; I installed it on a Linux RedHat 
7.3, my target is SPARC ERC32. I run my application using the ERC32 
simulatoror within sparc-rtems-gdb.

I tried with this simple example (see code below). I set up 
CONFIGURE_MICROSECONDS_PER_TICK 1000 and I ask 
rtems_task_wake_after(10000) whitch for me means that the task should be 
blocked for 10s.
I have two problems:
-rtems_task_wake_after instead of waking after 10s wakes after 1s
-after 30 iteration the process doesn't go on; in the debugger I saw 
that it is in the funtion _CPU_Thread_Idle_body ()

If I askrtems_task_wake_after(1000) rhe process doesn't freeze, but the 
time scale is still wrong.
 
Can anyone of you help me?

Thank you very much in advance

my code:

#include <bsp.h>

#include <stdio.h>

#include <rtems.h>

rtems_task user_application(rtems_task_argument argument);

rtems_task Init(
  rtems_task_argument ignored
)
{
rtems_id tid;
rtems_status_code status;
rtems_name name;



    name=rtems_build_name('A','P','P','1');

    
status=rtems_task_create(name,10,RTEMS_MINIMUM_STACK_SIZE,RTEMS_DEFAULT_MODES,RTEMS_DEFAULT_ATTRIBUTES,&tid);

    if(status!=RTEMS_SUCCESSFUL){
        printf("rtems_task_create failed with status of %d.\n",status);
        exit(1);
    }

    status=rtems_task_start(tid,user_application,0);


    if(status!=RTEMS_SUCCESSFUL){
        printf("rtems_task_start failed with status of %d.\n",status);
        exit(1);
    }

    status=rtems_task_delete(RTEMS_SELF);

    printf("rtems_task_delete returned with status of %d.\n",status);
    exit(1);
}

rtems_task user_application(rtems_task_argument argument){
rtems_interval inter=10000;
int i=0;
    while(1){
        printf("user_application %d\n",i);

        rtems_task_wake_after(inter);

        i++;
        if(i==100){
            rtems_shutdown_executive(0);
        }
    }

}
