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.

Downloaded this "program" a couple days ago (April 10, 2018) and it still has this problem. They still haven't fixed it. It's so sad 😑
