Error updating firmware: "Resource busy: /dev/cu.wlan-debug"



  • Hi Everyone. I'm trying to update the firmware with pybytes of a new chip I bought
    Chip: Lopy4
    Board: expansion board V3.1
    Computer: MacBook M1, macOS 11.0.1

    I make sure I close Atom and any related processes before running the software. However, when I try to update the firmware I get the message
    "Resource busy: /dev/cu.wlan-debug"

    I searched on google and found no answer. Has anyone encountered the same error and knows how to solve it?
    Many thanks!
