how call function on hardware exceptions

Hey guys now i have good news. Interruptions are working here!

I make a single exemple for help others guys:

/********************************************************/

My context: I have 1 IRQ on my system. IRQ N.º 1.

/********************************************************/# include <stdio.h># include <sys/alt_irq.h>

/********************************************************/

int main(){

alt_u32 id = 1;

volatile int button=1;

printf("start:\n");

alt_irq_register( id, (void*)&button, my_isr );

while(1){

if(button!=0){

printf("exception runing...\n");

button=0;

}

else

printf("main runing... \n");

}

return 0;

}

/********************************************************/

static void my_isr(void* context, alt_u32 id)

{

int* button = (int *)context;

if( id == 1 ) //test interruption id

*button = 1;

else

*button = 0;

}

/********************************************************/
