Trying to run Micropython on Nano RP2040 Connect

Official Hardware Nano Family Nano RP2040 Connect

I am having trouble trying to run Micropython on a Nano RP2040 Connect. I tried the Micropython Installer https://labs.arduino.cc/en/labs/micropython-installer first for Linux, which wouldn’t install on my computer. I switched to trying the Installer on Windows, which does install and run. However, it either does not see the Nano as connected, or it errors in trying to load the Micropython UF2 file (ARDUINO_NANO_RP2040_CONNECT-20251209-v1.27.0.uf2). I can manually put the Nano in bootloader mode, where it shows up as a USB device “RPI-RP2”, and then copy the Micropython UF2 to the device. The problem is, when I do this, the Nano never comes out of bootloader mode: I can continue to see it as a USB device. I can reload the “Blink.ino.elf.uf2” from Arduino, and the Nano begins to work as expected, with blinking LEDs and disappears as a USB device.

Am I doing something wrong in the sequence of things? Or do I have the wrong Micropython UF2 file?

Ok, I got it to work. Don’t know exactly what I did different from above, but manually putting into bootloader mode (two presses of the button), then copying the Micropython UF2 to the device worked. Now I can get the Python REPL and run a short Python program, using Thonny.

My guess is that Thonny was trying to use the wrong COMM port.
