Wire it up to your STLink V2 as follows:
Wire + = 3v3
, - = GND
, C = CLK
and D = DIO
to their respective pins on the RX from the StLink.
Because those pins are so small one option is to only solder a wire on the CLK
and DIO
then power it with the 5v pin with an external power source.
Disable 'Readout Protection'. To do this download the ST-LINK Utility and follow this quick how to video. Or alternatively under linux you can use OpenOCD.
How to video:
Using the correct target specific for your receiver, and your Firmware Options set, click Build & Flash on the ExpressLRS Configurator.
After the flash is successful, desolder the STLink and connect RX2 and TX2 (you will need to solder on the STM32 pins, see picture) to a flight controller and setting up the receiver with the CRSF serial protocol.
