Hi,
my example code of led blinking not working with platformio on VSCode and Atom, code is successful uploaded but my nucleo board do not anything. On System Workbench for STM32 all works fine. IDE is on default settings. I tried reinstall VSCode and platformio, but still not working. I have latest updated IDE and stm32 boards module.
Here is example code: https://pastebin.com/zemYPUZA
