Yes I've read it, but when I try this (on the older board, where the 
u-boot is working), the gdb doesn't stop at that function, just continue 
(and over the serial terminal, I see the normal u-boot messages, and 
later auto booting into linux).

Here is the screen dump of what I've done:

U-Boot $ powerpc-linux-gdb u-boot

Breakpoint 1 at 0xfff03a34: file cpu_init.c, line 53.
(gdb) c

and I don't get the GDB prompt back unless I press CTRL+C.

Any idea?
