Hi,

I'm under the impression that when flashing from the CLI (on linux or windows), all I need to do is select the correct COM/tty and flash the chip.

On the M0S dock, I'm also supposed to press the "BOOT" key at some point. Still, no matter when I press it (before power, after power, before and during flash), I get this log (on windows and linux, from CLI and from Bouffalo Lab Dev Cube...):
