I would like to leverage uf2 to simplify the upgrade of micropython firmware. I have UM ProS2 board which come with the UF2 bootloader. However the uf2 firmware I downloaded from the site does not work on the board.

Yes my understanding (from https://github.com/micropython/micropython/issues/8222 and https://github.com/micropython/micropython/pull/8246) is that this is supposed to work, but I have not tried it myself.

You might want to try the UM discord -- https://discord.gg/xAHpApP

I can successfully upload the uf2 firmware onto the board, but it seems there is a bug which render the flash storage not accessible. So it is pretty useless right now. Also is there instructions on how to build your own uf2 firmware? As I build firmware with my own frozen lib, the current build only produce firmware.bin not firmware.uf2.
