Flashing

UF2

The Wio Terminal comes with the UF2 bootloader already installed.

CLI Flashing

  • Plug your Wio Terminal into your computer’s USB port.

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

    tinygo flash -target=wioterminal [PATH TO YOUR PROGRAM]
    
  • The Wio Terminal board should restart and then begin running your program.

Troubleshooting

If you have troubles getting your Wio Terminal board to receive code, try this:

tinygo flash -target=wioterminal [PATH TO YOUR PROGRAM]

Once you have updated your Wio Terminal board the first time, after that you should be able to flash it entirely from the command line.

Notes

You can use the USB port to the Wio Terminal as a serial port. UART0 refers to this connection.
