| <p>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</p> |
| </section> |
| <section id="usage"> |
| <h2>Usage<a class="headerlink" href="#usage" title="Permalink to this heading"></a></h2> |
| <ol class="arabic simple"> |
| <li><p>Compile nuttx with CONFIG_DEBUG_SYMBOLS=y</p></li> |
| <li><p>Use gdb to debug nuttx elf.(real device, or sim, or coredump)</p></li> |
| <li><p>add args to gdb command line: -ix=”nuttx/tools/gdb/__init__.py”</p></li> |
| <li><p>Then gdb will load the python script automatically.you can use the custom commands.</p></li> |
