Building OpenOCD from Sources for Linux
The following instructions are alternative to downloading binary OpenOCD from Espressif GitHub. To quickly setup the binary OpenOCD, instead of compiling it yourself, backup and proceed to section Setup of OpenOCD.
Download Sources of OpenOCD
The sources for the ESP32-S2-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.
sudo apt-get install make
sudo apt-get install libtool
sudo apt-get install pkg-config
sudo apt-get install autoconf
sudo apt-get install automake
sudo apt-get install texinfo
sudo apt-get install libusb-1.0
Note
Version of pkg-config should be 0.2.3 or above.
Version of autoconf should be 2.6.4 or above.
Version of automake should be 1.9 or above.
When using USB-Blaster, ASIX Presto, OpenJTAG and FT2232 as adapters, drivers libFTDI and FTD2XX need to be downloaded and installed.
When using CMSIS-DAP, HIDAPI is needed.
Build OpenOCD
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
.
Once make
process is successfully completed, the executable of OpenOCD will be saved in ~/openocd-esp32/bin
directory.
Next Steps
To carry on with debugging environment setup, proceed to section Configuring ESP32-S2 Target.
