1. Read c/src/lib/libbsp/i386/pc386/HOWTO

2. Add following fragment to the init task
#if 1
  /* Init GDB glue  */

  if(BSPConsolePort != BSP_UART_COM2)
    {
      /*
       * If com2 is not used as console use it for
       * debugging
       */
      i386_stub_glue_init(BSP_UART_COM2);
    }
  else
    {
      /* Otherwise use com1 */
      i386_stub_glue_init(BSP_UART_COM1);
    }

  /* Init GDB stub itself */
  set_debug_traps();

  /*
   * Init GDB break in capability,
   * has to be called after
   * set_debug_traps
   */
  i386_stub_glue_init_breakin();

  /* Put breakpoint in */
  breakpoint();

#endif  /* 0 */
