    I upgraded to IDE 2.0.1. It works on my Arduinos perfectly. However, the controllino script compiles, but does not upload:

    Failed uploading: cannot execute upload tool: fork/exec /Users/wolfgang/Library/Arduino15/packages/arduino/tools/avrdude/6.3.0-arduino8/bin/avrdude: bad CPU type in executable

    Yes, Controllino Maxi Automation is selected 😉

    System used: Mac OS 13.0 on a Intel i7 MacBook Pro

    Anyone knows how to overcome this?

    thx, Wolfi

      The only way to solve it for me was to roll back to the old Arduino Version.

      It kinda sucks, but it works.

    Hallo Wolfi,

    I have the same problem. My workaround is that I use the “avrdude/6.3.0-arduino17”

    My “failing” command is “/Users/xxx/Library/Arduino15/packages/arduino/tools/avrdude/6.3.0-arduino8/bin/avrdude” “-C/Users/xxx/Library/Arduino15/packages/arduino/tools/avrdude/6.3.0-arduino8/etc/avrdude.conf” -v -V -patmega2560 -cwiring “-P/dev/cu.usbmodem1411301” -b115200 -D “-Uflash:w:/private/var/folders/02/2m5xmk0j5bb19k5jt4lnh46h0000gq/T/arduino-sketch-B44509711192F6CF6691A744BF3E1B30/Lueftung.ino.hex:i”

    (This is the copy from output window of the IDE, last line, all possible output enabled)

    I open a terminal window and the I can load the hex file with:

    “/Users/xxx/Library/Arduino15/packages/arduino/tools/avrdude/6.3.0-arduino17/bin/avrdude” “-C/Users/xxx/Library/Arduino15/packages/arduino/tools/avrdude/6.3.0-arduino17/etc/avrdude.conf” -v -V -patmega2560 -cwiring “-P/dev/cu.usbmodem1411301” -b115200 -D “-Uflash:w:/private/var/folders/02/2m5xmk0j5bb19k5jt4lnh46h0000gq/T/arduino-sketch-B44509711192F6CF6691A744BF3E1B30/Lueftung.ino.hex:i”

    Make sure that the Serial Monitor is not blocking the “serial line”

    Does anyone have an idea how to fix this in the IDE?

      Hi all,

      we will try to fix this in the new release of the CONTROLLINO Library.

      I hope it happens in the next two weeks.
