[Xenomai-help] interrupt wait problem

[marcellin <marcellin.fotze@domain.hid>]

Hi, i'm trying to use the RealTimeClock IRQ 8, with a xenomai real time 
task. I configure the RTC to have a periodic interrupt on it with the 
linux standard API, and it works. After when i want to catch the IRQ 8 
in a xenomai real time task i have a problem a error ( " Operation not 
permitted ") with the " rt_intr_wait " fonction. Is there a special 
initialisation or configuration to make with the kernel or Xenomai ?


my conf : kernel 2.6.15.1 , Xenomai-2.1-rc4

in my program

//initialisation
             err = rt_intr_create(&intr_desc,"IRQ8",IRQ8,I_PROPAGATE);
             if(err){
           printf("AcqProcess -> failed to create interupt object : 
%s",strerror(-err));
       }
                  err = rt_intr_enable(&intr_desc);
             if(err){
           printf("AcqProcess -> failed to enable interupt object : 
%s",strerror(-err));
       }
             err = 
rt_task_create(&time_task,"SecondTask",TASK_STKSZ,TASK_PRIO,T_FPU|T_JOINABLE); 

       if(err){
           printf("AcqProcess -> failed to create task : 
%s",strerror(-err));
       }
              rt_task_start(&time_task,&timer_handler_thread,NULL);






//in the irq task


err = rt_intr_wait( &intr_desc,TIMEOUT );
                     if(err){
           printf("AcqProcess -> failed to wait interrupt : 
%s",strerror(-err));
       }
