=============== GDB with Python =============== Introduction ============ The NuttX kernel can be effectively debugged using GDB's Python extension. Commonly used classes and utilities are implemented in the nuttx/tools/gdb/nuttxgdb directory. Users can also create custom Python scripts tailored to their debugging needs to analyze and troubleshoot the NuttX kernel more efficiently. Usage ===== 1. Compile NuttX with CONFIG_DEBUG_SYMBOLS=y enabled and change `CONFIG_DEBUG_SYMBOLS_LEVEL` to -g3. 2. Use GDB to debug the NuttX ELF binary (on a real device, a simulator, or with a coredump). 3. Add the following argument to the GDB command line: `-ix="nuttx/tools/gdb/gdbinit.py"` 4. GDB will automatically load the Python script, enabling the use of custom commands. How to write a GDB python script ================================ Here is an article that introduces the fundamental principles of Python in GDB. Read it to gain a basic understanding. `Automate Debugging with GDB Python API `_. For more documentation on gdb python, please refer to the official documentation of GDB. `GDB Python API `_.
