Failed to send "Hello World" in Windows :)

  • Hi,

    When I select M5stack board and I try to send de example "Hello World" and doesn't works, it send a lot of errors, similar to the same FAQ of ubunto.

    I select the ESP32_Dev board and works! but.... the M5stack dosen't receive. Where is the prog button?

    I tryed a lot of times whit different speeds and only one works, whit Blink example.


    the erros is:
    Arduino:1.8.5 (Windows 10), board:"M5Stack-Core-ESP32, 80MHz, 921600, None"

  • I'm also experienceing the same problem. None of the examples i working.

    In my arduino output display I see a lot of undefined referece to .....

  • Not only windows also OSX.
    Please let me know if you know the reason.

  • I tried whit a board type ESP32-DEV and it's works.

    But I'm waiting for a answer of team because I think is better use the specific board M5Stack

    :) thanks

  • I've the same problem using Windows 10 - all examples produce error message like the one in the first post
