Flashing

UF2

The QT Py RP2040 comes with the UF2 bootloader already installed.

CLI Flashing

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

    tinygo flash -target=qtpy-rp2040 [PATH TO YOUR PROGRAM]
    
  • The QT Py RP2040 board should restart and then begin running your program.
