Problem when simulating an IRQ with the IAR tool

Hi,

Sorry for my bad writing.

I am triying to simulate an IRQ interrupt with IAR and C-SPY. I did the tutorial examples and I learn how an interrupt should be done but when triying to do the same thing with the examples that are in the STR71xLibrary folder ... the interrupt is done but it didn't jump to the 71x_it.c file (where the subroutine code is).

When running one of those examples (with interrupts), I notice that in the disasembly window, at the 0x18 address is a 000000; that means that the interrupt could not find the next address or the function that the PC need to do the jump.

I am using the IAR EWARM Kickstart version 4.40.

Could Anybody help me with this problem???

Thanks

Hi,

I think that the problem is with the 71x_vect.s and or the 71x_init.s; because the first one that is the noe that have the Handlers of the interrupts... it's never opened during the debbugging.

I am just a begginer about STR711 microcontrolles and a need a little bit of help on this.

Could any body help with my problem?

Thanks.
