FULL

Update OS and installed apps, download latest esp-open-sdk and micropython, build everything, erase and upload new binary to /dev/ttyUSB0

MAKE-ONLY

Download latest esp-open-sdk and micropython, build everything.

Download latest micropython and build (skip esp-open-sdk).

Only writing existing flash to device. (no updates, no build)
