[rtl] data read error

[Massimiliano Cialdi]

I use Comedi 0.7.60 and rtlinux 3.1 (linux 2.4.4), and I have PIC-6024E
board.
I tried to use the following:

-------------------------------------------
#include <time.h>
#include <pthread.h>
#include <linux/comedilib.h>

pthread_t thread;

void * start_routine(void *arg)
{
  lsampl_t data;

  pthread_make_periodic_np (pthread_self(), gethrtime(), 500000000);

  while (1) {
    pthread_wait_np ();
    if(comedi_data_read(0,0,0,0,AREF_DIFF,&data)<0)
      rtl_printf("error\n");
    else
      rtl_printf("ho letto %d\n",(int)data);
  }
  return 0;
}

int init_module(void) {
  int subdv,i,nchan,type;
  if(comedi_open(0)<0)
    rtl_printf("non apro\n");
  return pthread_create (&thread, NULL, start_routine, 0);
}

void cleanup_module(void) {
  comedi_close(0);
  pthread_delete_np (thread);
}
----------------------------------------

during the execution the following error occurs during
comedi_data_read():
ni_E: timeout 2

sometimes I obtain a different one:
ni_E: timeout 1

I wonder if there is an error in the code or if the board is broken.

thanks and sorry for my english
