How to enable interrupt in QNX7.0 ?  
Hi everyone

I installed QNX7.0 on my BeagleBone Black. BBB has AM335x SoC which contains PRU-ICSS however, by default, interrupts 
from PRUs are disabled - in QNX buildfile system interrupts 20-27 (PRU events) are marked as "Reserved":

## vector:    20 - 27
## trigger:    N/A
## device:    Reserved

I would like to enable it. Does anyone know how to do that?

Additionaly, I am not sure what "Reserved" means. On the begining I thought that "Reserved" means that there is no 
handler for these interrupts so sending it would cause system crash. I also thought that maybe there is some very simple
 handler which does nothing but erasing the source of the interrupt. However, when I generate interrupt from PRU, the 
main INTC does not even get this interrupt - ITR register is clear  - how is that possible?  

Regards
