1. Add GDB initilization to your target's code:
2 
 
3 
a) include file:
4 
 
5 
#include
6 
 
7 
b) declare this variable:
8 
 
9 
extern int BSPConsolePort;
10 
 
11 
c) To start-up GDB, run this:
12 
 
13 
 /* Init GDB glue  */
14 
 
15 
  if(BSPConsolePort != BSP_UART_COM2)
16 
    {
17 
      /*
18 
       * If com2 is not used as console use it for
19 
       * debugging
20 
       */
21 
      i386_stub_glue_init(BSP_UART_COM2);
22 
    }
23 
  else
24 
    {
25 
      /* Otherwise use com1 */
26 
      i386_stub_glue_init(BSP_UART_COM1);
27 
    }
28 
 
29 
  /* Init GDB stub itself */
30 
  set_debug_traps();
31 
 
32 
  /*
33 
   * Init GDB break in capability,
34 
   * has to be called after
35 
   * set_debug_traps
36 
   */
37 
  i386_stub_glue_init_breakin();
38 
 
39 
  /* Put breakpoint in */
40 
  breakpoint();
41 
 
42 
d) This is all you need to do for the target.
43 
 
44 
2. Edit cmds: specify path to current directory and device used for debugging
45 
   example of cmds is attached below.  Make sure your paths are correct.
46 
3. type 'make'
47 
4. Boot o-pc386/.exe on target computer, where  has the code from step 1. ( I modified and recompiled base_sp as the  )
48 
5. run 'i396-rtems-gdb --nx --command=./cmds o-pc386/.coff
