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.
Do I need to install the external tools if I already have installed the latest arm-none-eabi-* and openocd using my system's package manager? If the answer is yes, can be any conflicts?
