Pi Pico 2 uf2 file for RP2350

[clovisf]

Hi all,

I bought a Xiao RP2350 and am running Arduino code in it no problem. Now I want to run micropython in it, and the official guide https://wiki-seeedstudio-com.translate.goog/getting-started-xiao-rp2350/ states that I need to install the uf2 file that best suits my board.

The problem is that in the official micropython website there is no mention at all about the Xiao RP2350 line, and when I install the "vanilla"uf2 for the Pi Pico 2 in my RP2350, it does not get recognized by Thonny IDE. It does "accept" that I drag & drop the file but does not show up as a COM port afterwards.

Also the Thonny IDE itself has a "board update" feature which I use and it does its thing. But also the board is not recognized by Thonny.

I just downloaded Thonny 4.1.7 and my RP2350 is brand new. My info_uf2.txt inside the Xiao reads:

"UF2 Bootloader v1.0
Model: Raspberry Pi RP2350
Board-ID: RP2350"

I also should add that an original Pi Pico 2 works just fine with Thonny IDE.

Note Micropython issue.

also mentioned here https://wiki.seeedstudio.com/getting-started-xiao-rp2350/
In both they give you uf2 file. Take that file and copy it in explorer to the RP2350 drive created by boot mode. Done.

Thank you.

MicroPython Firmware Issue
As of November 10, 2024, the stable MicroPython firmware version 1.24.0 available for download at MicroPython.org for RPI_PICO2 is currently incompatible with certain devices due to variations in the flash chip.

The Seeed Team is actively working to resolve this issue in collaboration with the official MicroPython maintainers. In the meantime, you can use a preview version of the MicroPython firmware as a temporary solution: RP2350 MicroPython Firmware Preview

This is the link. I have tested copying it to my pico 2 and to my custom RP2350B board and both worked great. https://files.seeedstudio.com/wiki/XIAO-RP2350/res/RPI_PICO2-20240809-v1.24.0-preview.201.g269a0e0e1.uf2
