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.
Maybe one extra info:
I can debug each single MCU on the STM32CubeIDE, but I would like to debug both MCU's at the same time. Is there's a way to to that using the STM32CubeIDE? Up to now, I'm trying to make it work on the STM32 Workbench.
