StarterWare interrupt problem

Hello!

I am new to omap and decided to start with StarterWare uart example project. So I import it to CSS 5.5 and try to compile without any changing. The project has been compiled successfully and I can send and receive data by using StarterWare uart functions..

But I have a problem, that uart interrupt doesn't seem to occur .. The code within the uart interrupt handler does not seem to execute, and a breakpoint that is placed within the ISR never pauses execution.. But, as i can see in uart Interrupt Identification Register (IIR), IPEND is forced to zerro and INTID flags shows the right interrupt type..

I have checked that all ARM interrupt controller registers are set correctly and IRQ is enabled.. Where the problem can be?

Then I have tried StarterWare timer example project ang have got the same result - Timer ISR function does not seem to execute during debugging..

I use Blackhawk usb100v2 emulator and omap l138 evm development kit.. Is it possible, that emulator blocks interrupts during program debugging?
