Development tools for Zephyr on STM32Workbench for Zephyr: VS Code extension to set up, build, flash and debug Zephyr applications on STM32.Devicetree manager: browse, edit and visualize Zephyr devicetree, STM32CubeMX-like for Zephyr.
I would like to thank you, I'm now able to upload code withour error, even if some error stills appears in OpenOCD console, the final result is ok. Now it's time to focus on CubeMX and software rather than digging around IDE setup !
