What makes you think GDB would show something different from the code
you get from disassembling the same object files?

With the BDI's telnet interface: "reset", "ti", "ti", ...; with  GDB:
"target  remote  bdi:2001",  "detach",  "target remote bdi:2001", (*)
"si", "si", ...

(*) a "display/i $pc" might be useful here...

Best regards, and a Happy New Year!
