Hi,
Has anyone observed and solved the following?
After some time (a few minutes to a few hours) of operation, the RT task I
am running stops without any message. If I rmmod and insmod it again, it
will run for about a seconds before it stops again. If I re-insert
rtl_sched and rtl_time and my module, it will run again for some time
(~min-hours) before stopping.
My task is really simple, it only flips a bit on the parallel port. I have
tried task periods between 50us and 1ms and it appears to run longer the
longer the period.
void *rtfunc( void *param )
{
unsigned char value = 0;
unsigned char mask = 0x01;
pthread_make_periodic_np( thread, gethrtime() + PERIOD, PERIOD);
while ( 1 ) {
pthread_wait_np();
rtl_outb( value, PORT );
value ^= mask; // Toggle bit
}
return 0;
} /* rtfunc */
RTLinux 3.1, Linux 2.4.4, CPU AMD 5x86, gcc 2.96 (from RedHat 7.2).
I found an earlier post about a similar problem with an older version of
RTLinux and the reply was that it had been fixed in the 3.0 release.
Hope someone can help, this is getting a bit annoying.
Kris
