My problem arises when I try to do exactly what's shown in the FAQ
(before relocation, in this case).

Instead of:

Breakpoint 1, cpu_init_f () at cpu_init.c:136
136             asm volatile("  bl      0f"             ::: "lr");
(gdb) s
137             asm volatile("0:        mflr    3"              ::: "r3");
(gdb)

I get:

Breakpoint 1, cpu_init_f (im=0xe0000000) at cpu_init.c:42
42      {
(gdb) s
Cannot access memory at address 0xfd000ed8
(gdb) print im
$1 = (volatile immap_t *) 0xe0000000
(gdb) print *im
Cannot access memory at address 0xe0000000
(gdb)

Uncool.

Ben
