Debugging with GDB

Prerequisites

• Firebird v0.20 or later, with the GDB stub exposed on port 3333
• GDB with ARM support
• Ndless 3.9.x or later installed

Procedure

1. Start the emulation
2. Connect GDB (arm-none-eabi-gdb -ex "target remote :3333" program.elf)
3. Set breakpoints (optional) and continue execution with (cont)
4. Start the program from the document browser
5. Debug

Note that most IDEs allow using the GDB protocol to debug programs. I only tested Qt Creator with this, just select Debug -> Start Debugging -> Attach to Running Debug Server
