The GNU debugger is a command-line program that provides a very rich set of options.
You'll find a tutorial-style doc called "Using GDB" as an appendix in this manual.
You can invoke gdb by using the following variants, which correspond to your target platform:
| For this target: | Use this command: |
|---|---|
| ARM | ntoarm-gdb |
| Intel | ntox86-gdb |
| MIPS | ntomips-gdb |
| PowerPC | ntoppc-gdb |
| SH4 | ntosh-gdb |
For more information, see the gdb entry in the Utilities Reference.
