Still required to set a serial port?

There is automated discovery of boards in bootloader mode, so they show up in the IDE, and the upload command works using the Microsoft UF2 tool (included).

I was still required to set a serial port before uploading code to the board? Upload proceeded by copying a UF2s expected after I'd done that (it works!), but having to set a serial port is going to be pretty confusing, and some users may not have any serial port options offered to them so will be unable to proceed?

If you manually reboot into UF2 mode, it should just work w/o a serial port (the 1200bps twiddle won't be done). Is that not the case for you?

I think it may be more of a documentation thing, because after that 1st load the serial port will (should) auto-list and it's no different than, say, an AVR or ESP8266 where you set the port once and it just sticks...

Just updated the README.md with a note about this. Think we're good here, thx!

Oh. I've figured it out. It works out of the box for production Picos, but I was using a pre-launch prototypes which has some differences. That explains that then. Apologies!
