An Example for ESP32 Debugging via OpenOCD

Build OpenOCD from Source

• Prepare:

sudo apt-get install build-essential automake autoconf texinfo cmake libtool pkg-config libusb-dev libusb-1.0.0-dev libftdi-dev

• Call build.sh to build openocd-esp32_espressif from scratch.

Quick Start

• Plug the BusBlaster adapter as the first usb device, and
• Run openocd.sh as gdbserver, then
• Use debug_esp32.sh as command-line debugger version, or
• Use the debugging function in Vscode (please extract blink_lolin32_debugging.tar.gz and open the folder).

Quick Fix

Use fix_openocd-esp32_espressif_compile-error.patch for solving compilation error in openocd-esp32_espressif submodule. Just call patch.sh. Currently, it is called along with build.sh.
