Yeah, I figured out that I can break at main, but I'm trying to figure
out why:
(gdb) tar sim
Connected to the simulator.
(gdb) load
(gdb) p $pc
$1 = 0
(gdb) x/i 0x0
0x0: Cannot access memory at address 0x0
(gdb)
So the simulater starts out at 0x0 which doesn't make sense. Where
does gdb change its mind and figure out where to start?
BTW, how do I use the 'built-in' serial port in the ppc simulator?
