STM32Cube IDE 1.12.0. What version GNU Tools from STM32Cube IDE 1.6.1 and how to install them?
I have a client project using Cube IDE 1.6.1, not willing to install Cube IDE next to the already installed Cube IDE 1.12.0, was it possible to downgrade the GNU tool and if so what version to use and how.
