Arduino COM port problem with PICO and PICO2

Software IDE 2.x
1

I have just installed IDE 2.3.2 on Windows 11
I also followed these instructions for the PICO boards

When I connect a PICO or PICO 2 to a USB port, no new COM port is allocated.
If I hold the button down before I plug into the USB I get an "Autoplay RP2350" device appearing as a disk drive.

In the IDE status bar it now says
"Raspberry Pi PICO 2 on UF2 board"

Should this say on "COM x" ?

If I try to compile and upload a sketch at this point it ends with
Flashing G: (RP2350)
Wrote 123392 bytes to G:/NEW.UF2

However, the IDE then shows and error
"No monitor available for the port protocol uf2conv. Could not connect to UF2_Board uf2conv port"

Any idea what is going on?

Thanks

Hi @marthr.

This is normal. When you have the Arduino IDE Serial Monitor running, it will attempt to connect to the selected port at the end of the upload. As the name indicates, the Arduino IDE Serial Monitor can only be used with serial ports, so when you have the "UF2" port of the Pico selected, Serial Monitor is not able to connect.

You should note that the error from Serial Monitor is completely separate from the upload process. The upload was successful and the Pico is now running whatever sketch you uploaded to it.

Check Arduino IDE's Tools > Port menu to see if a serial port is now listed for the Pico. If so, you can select that serial port and then Serial Monitor will work as expected.
