Flashing
UF2
The Pico 2 comes with the UF2 bootloader already installed.
CLI Flashing
-
Flash your TinyGo program to the board using this command:
tinygo flash -target=pico2 [PATH TO YOUR PROGRAM] -
The Pico 2 board should restart and then begin running your program.
Troubleshooting
Any troubleshooting tips go here.
Notes
You can use the USB port to the Pico 2 as a serial port.
TinyGo has support for the RP2350’s on-board Programmable Input/Output (PIO) block.
