I can't get an interrupt on the ARM side (ARM works with SYSBIOS)

I try to get an interrupr from GPIO bank 2 on the ARM side (it works with SYSBIOS 6). It looks strange 'cause I thought it'll be easy to configure interrupts with SYSBIOS similarly to DSP side. My ISR function doesn't execute although I can see a pending flag in the periphery register.

I use the interrupt number 4, pin 4 from the gpio bank 2. The event number is 44 for the gpio bank 2.

These are several screenshots which will help to understand a problem:

This is a flag of the interrupt

This is a state of the interrupt enabling:

Some registers:

Vector locations and memory map:

SYSBIOS config:

Could anybody explain what is wrong?
