Firmware update on Duet 3 via USB and BOSSA - problem



  • Hello, I need some help/explanations too.
    Just got myself a duet3, seller already provided SD with some files. I want to run it in standalone mode (no RPi).
    I decided to upgrade firmware via USB as on guide: https://duet3d.dozuki.com/Wiki/Getting_Started_With_Duet_3#Section_Updating_Duet_3_main_board_firmware
    Steps that I've followed:

    1. Downloaded and installed BOSSA
    2. Shorted ERASE header with jumper
    3. Connected duet3 via USB to laptop (WIN 10 64bit)
    4. Windows correctly sees board: BOSSA Program Port (COM4)
    5. I wanted to download latest firmware from: https://github.com/dc42/RepRapFirmware/releases Release 3.01-RC5
    6. Here is where problems start. There are many files, and it isn't clear which is correct. I've tied to download all .bin files (Duet3Firmware_MB6HC, Duet2CombinedFirmware etc. ) When I want to use BOSSE and write I got "file does not exist"

      No idea what I am doin wrong, "send help" 🙂

    Kind regards,



  • @Mandragora said in Firmware update on Duet 3 via USB and BOSSA - problem:

    Duet3Firmware_MB6HC

    is the correct file. but why you get the message the file doesn't exist is a bit of a puzzle.

    The biggest question is however, why not put that file on the SD card and upgrade with M997 instead of erasing the board and resorting to the recovery procedure - did something else happen?

    edit: you could try the command line version, open a command line prompt and try

    cd Downloads
    "C:\Program Files (x86)\BOSSA\bossac.exe" -d -e -w -v -b Duet3Firmware_MB6HC.bin -R
    


  • Thanks for your reply.
    I am not very familiar with this "software stuff" like gitlab etc. USB seemed easiest option since I don't have router around and my internet connection for computer is via Ethernet (so while connecting duet to laptop via Ethernet I don't have access to internet to look for help).

    It seems that your solution worked:

    Red DIAG LED is now flashing (1Hz)

    Now I will connect duet to laptop via Ethernet to check if I can see web interface etc.

    THX a lot for your help, I've spend 3h yesterday to figure out what was wrong.



  • Ok, after successfully reinstalling firmware, I was able to connect to board with YAT via USB. After some debugging I created new configuration and web interface on new SD card - just to be sure (provided one was missing most of the files).

    And BAM, DWC is present, now I can work from here.
