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, What is the board you are using (STM32F407G-DISC1 or STM32F429I-DISC1)?
What is the version of the SPL and the SW4STM32?
I just downloaded a GPIO example project (from Cube FW F4 V1.13) into a STM32F429I-DISC1 and it works.
