This example shows how to use gdbstub and it's functionality at runtime to debug an application with GDB.
|
||||
With the gdbstub component it is possible to run GDB from IDF Monitor by pressing Ctrl+C and debug
|
||||
the application using GDB. It is also possible to read/modify memory values, interrupt and continue the application.

the application using GDB. It is also possible to read/modify memory values, interrupt and continue

the application, set breakpoints, make steps and so on.
|

Upon exit from GDB, the application will continue to work in IDF Monitor as before.

The example can run on any commonly available ESP32 development board.
|

There are two possible ways to execute gdbstub with GDB: from IDF Monitor and as standalone application.
|
||||
gdbstub support ESP32, ESP32-S2 and ESP32-S3 chips.

Depending on the project, following settings could be used:

The user can enable or disable task list handling and define a maximum amount of tasks.

Note that gdbstub can now only be used when FreeRTOS is run on the first core only.

|
||||
The user can check again that the application has worked by checking variable "print call_count".
|
||||
The user can exit from GDB to continue seeing the trace from IDF Monitor by pressing "quit" and then "y".
|
||||
The user will see in IDF Monitor that call_count and logging level have changed.
|
||||
The user can add breakpoint to the label test_point2 by entering "break test_point2" and then enter "continue" or "c". The application will break at this line.
|
||||
If user will continue again, the application will break at this line again.
|
||||
Also, user can try to step application by entering "si".
