4. Unable to burn to Atom

Unable to burn to Atom

  • V

    I just got an Atom-Matrix. Downloaded the current burn software.

    Windows 10 computer. When I plug in the Atom, Windows sees it, and sets up a COM port (COM4).

    But I cannot seem to get the ATOM into download or setup mode.

    If I hold the button down while plugging it in, the display is blue.

    If I do NOT hold the button down while plugging it in, the display is green.

    But no matter how long I hold it down, it never turns yellow.

    Nor does it show up as an access point.

    When I try the burn program, I get this in the console log:

    Start Burn

    I figured it out. There are two sets of instructions on flashing. One says to set the baud to 921600 and hold down the center button while powering on.

    The other says to set the baud to 750000 and Erase before you Burn. I followed those instructions, and it worked fine.
