PIO STLink Fix

Software Banner


PlatformIO has an older version of STLink. It is unable to communicate with the STM32L MCUs on some RXs.

Affected Receivers

  • (DIY) PP

Swapping out PIO's STLink folder contents with the current STLink will allow using the configurator with these RXs.

Go to your STLink folder

  • Copy contents of "ST-Link Utility"
    C:\Program Files (x86)\STMicroelectronics\STM32 ST-LINK Utility\ST-LINK Utility

Folder details
