SOLVED "DuetMaestroFirmware.bin" is not valid for this electronics

  • Hello,

    Following the release of Release 3.2.2 I wanted to update my Duet Maestro. currently running 3.1.1.

    the zip download from git hub uploaded in to the system folder via the web interface and unzipped okay the web interface then asked me if I wanted to install the new firmware when pressing yes I receive this message.

    "Firmware binary "DuetMaestroFirmware.bin" is not valid for this electronics"

    Double checking the spelling re-downloading and running M997 S0 I have not been able to install the firmware I have rebooted and tried a fed more times with the same error.

    Thanks for any help.

    Try downloading DuetMaestroFirmware.bin from the release separately, and see if you can install that to the Duet.

  • I removed DuetMaestroFirmware.bin from the sys folder then downloaded DuetMaestroFirmware.bin separately from GitHub, uploaded via web interface.

    This time no error mentioned and seemed to install However M115 reports 3.1.1? as below.

    FIRMWARE_NAME: RepRapFirmware for Duet 2 Maestro FIRMWARE_VERSION: 3.1.1 ELECTRONICS: Duet Maestro 1.0 FIRMWARE_DATE: 2020-05-19b2

    Odd, it's all working for me. I just downloaded and installed the zip for firmware 3.2.2 on a Maestro that was running 3.3beta1.

    Try downloading and installing the 3.2.2 zip file again.

  • Thanks for your help, Seems to be a Safari/ Mac M1 issue. Safari unzipped the download by default must have changed something in the process.

    After downloading the Zip on a Rpi4 it worked as expected via the web interface and M115 now reports 3.2.2.

    This issue is now resolved.
