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.
hi, i am running this on osx 10.11.6 without this problem, try to find console output from openocd or gdb which one fails. What are your sw versions? Which board you are trying to debug? Is programming without debug working?
