[ECOS] Create interrupt problem

["Vikas K. Prasad" <vikas dot prasad at ittiam dot com>]

Hi,

I was unable to attach an ISR properly.  I am  using a custom
board (with excalibur on it) on which the basic ecos features
are working and now I am testing the interrupts.

I used the following command:
cyg_interrupt_create((cyg_vector_t)TIMER1_VECTOR, /* Vector           */
                     (cyg_priority_t)TIMER1_PRI,  /* Priority         */
                     TIMER1_DAT,                  /* Interrupt data   */
                     (cyg_ISR_t*)timer1_isr,      /* ISR handler      */
                     (cyg_DSR_t*)timer1_dsr,      /* DSR handler      */
                     &timer1_handle,              /* Interrupt handle */
                     &timer1_obj);

With this after execution of the command I see that some
junk values are stored in timer1_obj.

(gdb) p/x * (cyg_interrupt*)timer1_obj
$16 = {vector = 0xe3a00a40, priority = 0xe3a01880, isr = 0xe0410000,
  dsr = 0xe04ff000, data = 0xe1a00000, dsr_count = 0xe59f022c,
  next_dsr = 0xe3a01007}

Because of this, hal_default_isr() is called and my ISR is never
hit. Can you please give me some clues as to where the problem
lies ? I am suspecting that the ISR routines are not not attached
properly. Anything that I need to specifically do in the platform
port for this?

Regards, 
Vikas
