Unfortunately the OpenOCD development is not very fast and the latest version is 0.10.0 from January 2017 (October 2019). This version does not support the STM32G0/STM32G4 as target, nor the ST-Link V3 on e.g. the Nucleo-G474RE board.

Fortunately, it is not so hard to compile OpenOCD yourself, especially under Linux.

1. Clone OpenOCD

Clone the Git Repo:

git clone http://openocd.zylin.com/openocd.git
cd openocd

2. Apply Patches for STM32G0 and STM32G4

Then additionally checkout the patch from http://openocd.zylin.com/#/c/4807/:

git fetch http://openocd.zylin.com/openocd refs/changes/07/4807/4 && git checkout FETCH_HEAD

3. Dependencies, Bootstraping, Configuring

Install libraries/dependencies, e.g. on Debian/Ubuntu:

apt install make libtool pkg-config autoconf automake texinfo libusb

Then run bootstrap and configure scripts:


The scripts inform you about missing libs. Just install the lib and run ./configure again.

4. Build and Install

Build and install OpenOCD. OpenOCD will get installed to /usr/lib/.

sudo make install

5. Uninstall OpenOCD

You probably want to uninstall the OpenOCD package from your distribution:

apt remove openocd

6. Udev Rules

Copy OpenOCD’s new udev file to /etc/udev/rules.d/ and reload udev rules:

sudo cp /usr/local/share/openocd/contrib/60-openocd.rules /etc/udev/rules.d/
sudo udevadm control --reload

Have fun programming STM32G0 or STM32G4 microcontrollers with OpenOCD!
