how can I catch an interrupt ?

[kang yunho]

This is my first message to this list.

I am a begginer user of RTEMS and I have to program a EP7312 

The program works O.K. except that I can`t execute muy own interrupt
routine 

I am using the "rtems_interrupt_catch" routine to assign my routine to
the
interrupt vector. The IRQ of the URXINT2 20

Does anybody tell me if I have to do something else or I have to change
any
configuration parameter?

The vector number to the rtems_interrupt_catch is my IRQ= 20?

Here is ep7312 irq.h, if you can look at it and tell me if there is 
something
wrong,
I will be gratefull for you for ever.
