| 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. |
