Hello,

For other ways of using GDB remotely (without JTAG), have you considered
gdbserver yet?  Take a look at:

http://sourceware.org/gdb/current/onlinedocs/gdb/Remote-Debugging.html#Remote-Debugging

and

http://sourceware.org/gdb/current/onlinedocs/gdb/Server.html#Server

As for the question regarding running GDB on a system without OS, others
can correct me if I'm wrong but I don't think it's possible because GDB
uses many OS-specific features (such as ptrace, and glibc functions).

Regards,

Sergio.
