Hardware debuggers will not work after the MMU has been enabled;
however, there should be no need to debug the startup library
code that is not board-specific; you could try putting a
kprintf in your startup’s main.c, just after the call to
kprintf(“in startup main…\n”);
If you see that output, then you can start sprinkling kprintf’s
throughout your startup code, to figure out where things are
