Dear Xenomai Team,
below is the simple program i want to run on xenomai ported pandaboard.The
make file iam using is as follows . what exactly i have to do
to compile and link this example to run on the arm based target board with
this make file.
#include <stdio.h>
#include <signal.h>
#include <unistd.h>
#include <sys/mman.h>
#include <native/task.h>
#include <native/timer.h>
#include <rtdk.h>
RT_TASK demo_task;
void demo(void *arg)
{
RT_TASK *curtask;
RT_TASK_INFO curtaskinfo;
// hello world
rt_printf("Hello World!\n");
// inquire current task
curtask=rt_task_self();
rt_task_inquire(curtask,&curtaskinfo);
// print task name
rt_printf("Task name : %s \n", curtaskinfo.name);
}
int main(int argc, char* argv[])
{
char str[10] ;
// Perform auto-init of rt_print buffers if the task doesn't do so
rt_print_auto_init(1);
// Lock memory : avoid memory swapping for this program
mlockall(MCL_CURRENT|MCL_FUTURE);
rt_printf("start task\n");
/*
* Arguments: &task,
* name,
* stack size (0=default),
* priority,
* mode (FPU, start suspended, ...)
*/
sprintf(str,"hello");
rt_task_create(&demo_task, str, 0, 50, 0);
/*
* Arguments: &task,
* task function,
* function argument
*/
rt_task_start(&demo_task, &demo, 0);
}
Make file.
