Flashing
UF2
The XIAO RP2040 comes with the UF2 bootloader already installed.
CLI Flashing
-
Flash your TinyGo program to the board using this command:
tinygo flash -target=xiao-rp2040 [PATH TO YOUR PROGRAM] -
The XIAO RP2040 board should restart and then begin running your program.
Troubleshooting
