How to flash a new firmware?

Really new to firmware flashing on the Picocalc and waiting for it, i wonder how :

  • Flashing a uf2 file to a pico1
  • Flashing a uf2 file to a pico2w (i got one to replace the pico1)

Thanks ! :blush:

It’s super easy. Push the button on the pico (you can see it through the casing slots) and keep it down as you connect a USB cable from its socket (not the USB C one) to your computer. The Pico will appear as a removable drive. Drag the .uf2 file to this drive. That’s it!

Thats amazing thanks!

Hm. When I press down & hold that white button on the Raspberry Pi 2W I installed in my PicoCalc (arrived yesterday) and then connect it via its Mini USB port to my Mac computer nothing happens.
No drive in Finder and not even a new serial device as /dev/tty* :frowning:
I tried in two ways:

  • just the Pico 2W connected to USB and main power of the PicoCalc turned off
  • just the Pico 2W connected to USB and main power of the PicoCalc turned on

No difference.
Should I connect the USB-C port to my Mac, too?

Do I need any special serial drivers on the Mac (running macOS 15.5)?

Also, which format should the SD card be formatted in? FAT32?

The Pico is a usb drive when in bootsel mode, not a serial device.

If it’s not showing any usb devices at all when plugged in, use a different cable. Chances are the one you are using is power only.

After you have connected the micro USB port on your Pico 2 W (not the USB-C port on your PicoCalc) to your Mac while depressing the BOOTSEL button, a USB Mass Storage device should appear on your Mac that you can mount and then copy a UF2 file to, which will be immediately flashed onto your board and booted into.
