m5stamp c3U on a mac using arduino side

  • I cannot get this to work at the moment I get an error
    I can see it on the USB port in Arduino and I did enable CDC on boot
    upload.tool.serial is undefined.

    By this I mean I create an empty file in Arduino and try to up load it

    documentation is a little sparse

    Any advice would be really appreciated

    Thank you
