The following instructions are alternative to downloading binary OpenOCD from `Espressif GitHub <https://github.com/espressif/openocd-esp32/releases>`_. To quickly setup the binary OpenOCD, instead of compiling it yourself, backup and proceed to section :doc:`setup-openocd-windows`.

Installation of ``pkg-config`` is breaking operation of esp-idf toolchain. After building of OpenOCD it should be uninstalled. It be covered at the end of this instruction. To build OpenOCD again, you will need to run ``pacman -S pkg-config`` once more. This issue does not concern other packages installed in this step (before ``pkg-config``).
