Flashing

UF2

The Sparkfun Thing Plus RP2040 comes with the UF2 bootloader already installed.

CLI Flashing

  • Flash your TinyGo program to the board using this command:

    tinygo flash -target=thingplus-rp2040 [PATH TO YOUR PROGRAM]
    
  • The Thing Plus RP2040 board should restart and run your program.
