gdb,
the debugging tool
To
run GDB on an embedded execution target, use a GDB backend with the GDB
standard remote protocol or a similar protocol. The most common are the
following two types of GDB backend.
A GDB stub
- This is an exception handler
for breakpoints, and it must be linked to your application. GDB stubs use
the GDB standard remote protocol.
An existing ROM monitor
used as a GDB backend
- The most common approach
means using the following processes.
- With a similar protocol
to the GDB standard remote protocol.
- With an interface that uses
the ROM monitor directly. With such an interface, GDB only formats and
parses commands.

with GDB in GNUPro Debugging Tools.
