[ECOS] problems with the user interupts on e7t can anyone help?

[F dot T dot Nilsson at hw dot ac dot uk]

Hi all,

could anyone help me with the interupt setting for e7t. I want to create an 
interupt if the user button is pressed. I created the interupts as follows 
butt nothing happens

void cyg_user_start(void)//void main(void)
{    
  printf("in cyg_user_start\n");

//*IOPCON = 0x10;

  cyg_interrupt_enable();
  cyg_interrupt_configure(CYGNUM_HAL_INTERRUPT_EXT0,1,1); //tried bot high 
and low detection	
  cyg_interrupt_create(CYGNUM_HAL_INTERRUPT_EXT0, 0, 0, &user_interupt,
        NULL, &user_int0, &intr);
	
  cyg_interrupt_attach(user_int0);
  cyg_interrupt_unmask(CYGNUM_HAL_INTERRUPT_EXT0); 

  cyg_thread_create(4,thread2 , (cyg_addrword_t) 0, "serial_poll",
        (void *)stack[0], STACKSIZE, &thread_handle[0], &thread[0]);
  cyg_thread_create(4, simple_prog, (cyg_addrword_t) 1, "serial2",
        (void *)stack[1], STACKSIZE, &thread_handle[1], &thread[1]);

  cyg_thread_resume(thread_handle[0]);
  cyg_thread_resume(thread_handle[1]);
}

I found a previous posting where the line *IOPCON = 0x10; was added. this 
makes it work but it detects an interupt without the button being pressed. 
I changed the configuration around but it doesnt't make a difference. do I 
have to manipulate the IOPCON and INTMASK registers manualy?

if anyone could help me with my little problem it would be much apreichiated

Cheers

fred
