=> TK71-Board (Marvell Kirkwood)

Application: a simple shell application 

system.h:
vvvv BEGIN vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv
#include <rtems.h>
#include <rtems/shell.h>
#include <bsp.h> 

#define CONFIGURE_APPLICATION_NEEDS_CONSOLE_DRIVER
#define CONFIGURE_APPLICATION_NEEDS_CLOCK_DRIVER
#define CONFIGURE_APPLICATION_NEEDS_LIBBLOCK
#define CONFIGURE_USE_IMFS_AS_BASE_FILESYSTEM
#define CONFIGURE_APPLICATION_NEEDS_RTC_DRIVER

#define CONFIGURE_MAXIMUM_TASKS                         32
#define CONFIGURE_MAXIMUM_SEMAPHORES                    20
#define CONFIGURE_MAXIMUM_MESSAGE_QUEUES                20

#define CONFIGURE_LIBIO_MAXIMUM_FILE_DESCRIPTORS        20

#define CONFIGURE_FILESYSTEM_NFS

#define CONFIGURE_RTEMS_INIT_TASKS_TABLE

#define CONFIGURE_MAXIMUM_POSIX_THREADS                 8
#define CONFIGURE_MAXIMUM_POSIX_SEMAPHORES              32

#define CONFIGURE_MAXIMUM_PERIODS                10
#define CONFIGURE_SCHEDULER_CBS
#define CONFIGURE_CBS_MAXIMUM_SERVERS            10

#include <rtems/confdefs.h>
^^^^ END ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Remarks:
========

I simply start a shell within the Init task without usage of the CBS scheduler.
This renders the shell as a background task.
