GDB with Python

Introduction

We can better debug the nuttx kernel through GDB’s python extension. Some of the most common class usages are implemented under the nuttx/tools/gdb directory. Users can write their own python scripts to debug the nuttx kernel according to their needs

Usage

1. Compile nuttx with CONFIG_DEBUG_SYMBOLS=y

2. Use gdb to debug nuttx elf.(real device, or sim, or coredump)

3. add args to gdb command line: -ix=”nuttx/tools/gdb/__init__.py”

4. Then gdb will load the python script automatically.you can use the custom commands.
