Building OpenOCD from Sources for Windows
|
||
*****************************************
|
||
|
||
The following instructions are alternative to downloading binary OpenOCD from Espressif website. To quickly setup the binary OpenOCD, instead of compiling it yourself, backup and proceed to section :doc:`setup-openocd-windows`.
|
||
|
||
|
||
.. highlight:: bash
|
||
|
||
Download Sources of OpenOCD
|
||
===========================
|
||
|
||
The sources for the ESP32-enabled variant of OpenOCD are available from 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.
|
||
|
||
|
||
Install Dependencies
|
||
====================
|
||
|
||
Install packages that are required to compile OpenOCD:
|
||
|
||
.. note::
|
||
|
||
Install the following packages one by one, check if installation was successful and then proceed to the next package. Resolve reported problems before moving to the next step.
|
||
|
||
::
|
||
|
||
pacman -S libtool
|
||
pacman -S autoconf
|
||
pacman -S automake
|
||
pacman -S texinfo
|
||
pacman -S mingw-w64-i686-libusb-compat-git
|
||
pacman -S pkg-config
|
||
|
||
.. note::
|
||
|
||
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``).
|
||
|
||
|
||
Build OpenOCD
|
||
=============
|
||
|
||
Proceed with configuring and building OpenOCD::
|
||
|
||
cd ~/esp/openocd-esp32
|
||
./bootstrap
|
||
./configure
|
||
make
|
||
|
||
Optionally you can add ``make install`` step at the end. Skip it, if you have an existing OpenOCD (from e.g. another development platform), as it may get overwritten.
|
||
|
||
.. note::
|
||
|
||
* Should an error occur, resolve it and try again until the command ``make`` works.
|
||
* If there is a submodule problem from OpenOCD, please ``cd`` to the ``openocd-esp32`` directory and input ``git submodule update --init``.
|
||
* If the ``./configure`` is successfully run, information of enabled JTAG will be printed under ``OpenOCD configuration summary``.
|
||
* If the information of your device is not shown in the log, use ``./configure`` to enable it as described in ``../openocd-esp32/doc/INSTALL.txt``.
|
||
* For details concerning compiling OpenOCD, please refer to ``openocd-esp32/README.Windows``.
|
||
|
||
Once ``make`` process is successfully completed, the executable of OpenOCD will be saved in ``~/esp/openocd-esp32/src/openocd`` directory.
|
||
|
||
Remove ``pkg-config``, as discussed during installation of dependencies::
|
||
|
||
pacman -Rs pkg-config
|
||
|
||
|
||
Next Steps
|
||
