Esp32 Debugger

Learn how to set up and use a debugger on an ESP32 board with an ESP-Prog and PlatformIO. Follow the step-by-step guide with pictures and a simple example project.

Learn how to use the official Espressif ESP-Prog tool and PlatformIO IDE to debug your ESP32 projects with JTAG. See how to set breakpoints, inspect variables, registers and assembly code, and troubleshoot ESP-IDF issues.

The ESP32 supports the JTAG debugging interface, which can allow users to debug their embedded applications through GDB much like they would debug a normal WindowsLinux executable. For instance, JTAG allows users to place breakpoints in code, view the memory stack, view registers, and more. However, most ESP32 boards on the market do not

Learn how to use the Arduino IDE to debug the Arduino Nano ESP32 board with the ESP32 Boards package and the Hardware CDC mode. Follow the steps to enter the debug mode, select the port, upload the sketch, and start the debugging session.

quotDebug gt Attach to Processquot button if your code has already been uploaded to the ESP32 board quotDebug gt Start Debuggingquot if your code has not been uploaded Congratulations - you should have the debugger running, and further windows can be opened from the quotDebug gt Windowsquot menu once you have started debugging .

The ESP32 microcontroller supports in-circuit debugging, i.e. your code can be run on real hardware while stepping through it line by line, running to the next breakpoint, inspecting variables etc. These instructions help you set up debugging, both for Arduino and ESP-IDF projects. Unfortunately, ESP32 debugging is unreliable as there are many things that can go wrong. Thus, this post also

In field GDB Command, enter xtensa-esp32-elf-gdb to invoke the debugger. Change the default configuration of the Remote host by entering 3333 under the Port number. Configuration entered in points 6 and 7 is shown on the following picture. Configuration of GDB Hardware Debugging - Debugger tab

Debugging the ESP32-C3. If you got one of the newer and more powerful RISC-V ESP32-C3s, then you're in luck, you don't need any additional hardware almost. The ESP32-C3 has a USB-to-JTAG converter inside the chip, which means that all we have to do is interface the ESP32-C3 with USB directly.

ESP32 device configuration for JTAG debugging. Some ESP32 devices e.g. ESP32 S3, ESP32 C3 have an eFuse that needs to be burnt using the serial port to enable using the JTAG pins, instead of JTAG programming via the USB interface - see here. Visual Studio Code configuration for debugging

Learn how to configure and run a debugger for ESP32 applications using Eclipse, command line, or idf.py. Find out the steps, parameters, and commands for GDB, OpenOCD, and hardware debugging methods.
