PIO STLink Fix
PlatformIO has an older version of STLink. It is unable to communicate with the STM32L MCUs on some RX's.
- (DIY) PP
Swapping out PIO's STLink folder contents with the current STLink will allow using the configurator with these RX's.
Go to your STLink folder
- Copy contents of "ST-Link Utility"
C:\Program Files (x86)\STMicroelectronics\STM32 ST-LINK Utility\ST-LINK Utility
- Paste files from "st-link utility" folder into "stlink" folder in your user PIO location
