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.
