4.17.7 Debugging Examples

This section is intended for users not familiar with GDB. It presents example debugging session from
simple application available under
1. Navigating through the code, call stack and threads
2. Setting and clearing breakpoints
3. Halting the target manually
4. Stepping through the code
5. Checking and setting memory
6. Watching and setting program variables
7. Setting conditional breakpoints
Similar debugging actions are provided using GDB from
Before proceeding to examples, set up your ESP32-S2 target and load it with get-started/blink.

4.17.8 Building OpenOCD from Sources

Please refer to separate documents listed below, that describe build process.
Building OpenOCD from Sources for Windows
The following instructions are alternative to downloading binary OpenOCD from
the binary OpenOCD, instead of compiling it yourself, backup and proceed to section
Note: Following instructions are assumed to be runned in MSYS2 environment with MINGW32 subsystem!
Install Dependencies Install packages that are required to compile OpenOCD:
pacman -S --noconfirm --needed autoconf automake git make
mingw-w64-i686-gcc \
mingw-w64-i686-toolchain
mingw-w64-i686-libtool
mingw-w64-i686-pkg-config
mingw-w64-cross-winpthreads-git

Download Sources of OpenOCD
Espressif GitHub under https://github.com/espressif/openocd-esp32. To download the sources, use the following
commands:
cd ~/esp
git clone --recursive https://github.com/espressif/openocd-esp32.git
The clone of sources should be now saved in ~/esp/openocd-esp32 directory.
Downloading libusb Build and export variables for a following OpenOCD compilation:
wget https://github.com/libusb/libusb/releases/download/v1.0.22/libusb-1.0.22.7z
