Flashing

UF2

The Feather RP2040 comes with the UF2 bootloader already installed.

CLI Flashing

• Plug your Feather RP2040 into your computer’s USB port while holding down the RESET button on the board.

• One plugged in, release the RESET button.

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

  tinygo flash -target=feather-rp2040 [PATH TO YOUR PROGRAM]
  

• The Feather RP2040 board should restart and then begin running your program.

Notes

You cannot yet use the USB port to the Feather RP2040 as a serial port. Instead UART0 refers to the TX/RX pins on the board itself.
