[Microbit-Python] Differences between BBC: microbit and pyboard

[Ben Mustill-Rose]

Hi,

Run
yt up
and then try
yt build
again. I have no idea why you have to do this but I've received the
same error a few times & doing this always solved it.

Having said this, as Carlos says, the easier (but less interesting)
way of getting a generic MicroPython hex file is to just extract the
runtime from uFlash. From memory the relevant line is 314.

Cheers,
Ben.
