Creation of initial task fails with RTEMS_UNSATISFIED

[Ingolf Steinbach]

Hi,

in my application, the creation of the initial task
(rtems_task_create() within _RTEMS_task_Initialize_user_tasks()
in cpukit/rtems/src/taskinitusers.c) fails with error
RTEMS_UNSATISFIED.

What configuration needs to be modified in order to
avoid the error?

A bit of additional information:

RTEMS configuration:
#include <rtems.h>
#define CONFIGURE_INIT
#define CONFIGURE_APPLICATION_NEEDS_CLOCK_DRIVER
#define CONFIGURE_INIT_TASK_ENTRY_POINT InitBoot
#define CONFIGURE_MAXIMUM_TASKS       1
#define CONFIGURE_MAXIMUM_TIMERS     1
#define CONFIGURE_RTEMS_INIT_TASKS_TABLE
#define CONFIGURE_INIT_TASK_ATTRIBUTES (RTEMS_DEFAULT_ATTRIBUTES | 
RTEMS_FLOATING_POINT)
#include <confdefs.h>

I have 512kB of RAM at location 0x40000000. The "end" symbol
is at 0x4001b268.


This is on RTEMS-4.6.5 on leon2.
