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-macos`.
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 packages that are required to compile OpenOCD using Homebrew:
brew install automake libtool libusb wget gcc@4.9
Proceed with configuring and building OpenOCD:
cd ~/esp/openocd-esp32
./bootstrap
./configure
make
Optionally you can add sudo 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 theopenocd-esp32
directory and inputgit submodule update --init
. - If the
./configure
is successfully run, information of enabled JTAG will be printed underOpenOCD 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.OSX
.
Once make
process is successfully completed, the executable of OpenOCD will be saved in ~/esp/openocd-esp32/src/openocd
directory.
To carry on with debugging environment setup, proceed to section :ref:`jtag-debugging-configuring-esp32-target`.
