Looks the same...Maybe something wrong i made with task initialization? I
took from guide example:
#include <stdlib.h>
#include <stdio.h>
#include <stdbool.h>
#include <bsp.h>
#include "rtems.h"
extern rtems_task hello_world(rtems_task_argument argument);
rtems_task init_tasks(__attribute__((unused)) rtems_task_argument ignored)
{
rtems_id tid = 0;
rtems_task_create(
rtems_build_name('M', 'I', 'M', 'U'),
1,
RTEMS_MINIMUM_STACK_SIZE,
RTEMS_INTERRUPT_LEVEL(0),
RTEMS_FLOATING_POINT,
&tid);
rtems_task_start(tid, hello_world, 0);
rtems_task_delete(RTEMS_SELF);
}
#define CONFIGURE_APPLICATION_NEEDS_CLOCK_DRIVER
#define CONFIGURE_APPLICATION_NEEDS_CONSOLE_DRIVER
#define CONFIGURE_RTEMS_INIT_TASKS_TABLE
#define CONFIGURE_MAXIMUM_TASKS 2
#define CONFIGURE_INIT_TASK_NAME rtems_build_name('T', 'E', 'S', 'T')
#define CONFIGURE_INIT
#include <rtems/confdefs.h>
