This is the link to the Seeed Xiao RP2350 board that I added recently: https://www.seeedstudio.com/Seeed-XIAO-RP2350-p-5944.html. Do you need us to provide any other information?

No, what you need to check in is tools/makeboards.py which (I hope) you added the new board to. If you just cut-n-paste or edited boards.txt in any way that's not going to work. You need to update makeboards.py, rerun it, and check in the new script and files. See the docs for more info.
