Just to make sure: to put a breakpoint on an address, it's "b *0x40000000" (i.e., with an extra "*"; but you'd notice if you used the wrong syntax, since gdb would complain that it can't find a symbol with that name).

Actually, I've noticed on many platforms that breakpoints on the very first instruction don't work. Did you also try other instructions?
