Flashing

UF2

The Nano RP2040 comes with the UF2 bootloader already installed.

CLI Flashing

• Plug your Nano RP2040 into your computer’s USB port while shorting the pins REC and GND with a jumper wire.

• Once plugged in, remove the jumper pin.

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

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

• The Nano RP2040 board should restart and run your program.

Notes

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