How to Upload UF2
Uploading a UF2 file to the Raspberry Pi Pico on a Linux system is straightforward. Here’s how you can do it:
Step 1: Prepare Your Raspberry Pi Pico
Enter Bootloader Mode:
- Hold down the BOOTSEL button on your Pico.
- While holding the button, connect the Pico to your Linux PC via USB.
- Release the BOOTSEL button.
- Check If the Pico Is Recognized:
Your Pico should appear as a mass storage device named RPI-RP2.
Verify using the following command:
lsblk
You should see a new device (e.g., /media/$USER/RPI-RP2 or /run/media/$USER/RPI-RP2).
Step 2: Copy the UF2 File to the Pico
cp your_firmware.uf2 /media/$USER/RPI-RP2/
Step 3: Run it
On PicoCalc, the default serial port of the Pico is the USB Type-C port, not its built-in Micro USB port.
So here is the standard running procedures:
- Unplug the pico from Micro-USB cable
- Plug the pico via USB Type-C
- Press Power On on Top of the PicoCalc
If your firmware includes serial output, you can monitor it using minicom or screen:
screen /dev/ttyACM0 115200
(Replace /dev/ttyACM0 with the correct serial port for your Pico.)
The serial monitor of Arduino IDE is another great choice for PicoCalc serial output on both Linux and Windows.
