      @szilveszter-zsolt said in Duet 2 wont start:

      We erased even the firmware and write an new one on formatted SD card but no success.
      The Boar no appear in device manager wen we plug the USB

      What do you mean write a new one on the formatted SD card?

      The flash the firmware you'll need to follow the link provided above.

      You may also find this guide useful for getting back up and running.

        hi,

        @phaedrux said in Duet 2 wont start:

        we have formatted the SD card, and downloaded from the Duet website the following files: Duet2_SDiap32_WiFiEth.bin, Duet2CombinedFirmware.bin, DuetWiFiServer.bin and put is on the SC card.

        Unfortunately no Bossa nor Duet ports appear in device manager. We have tried on a laptop too, without connected power, to avoid USB ground loops. WIN power is not connected to the board, from the moment we had communication issues. We tried with more USB cable on all the usb ports from the laptop, and on other 2 computers.

          @szilveszter-zsolt Remove the SD card from the SD card socket, and try connecting via USB and serial terminal again. I would guess that the SD card is causing a boot-loop, possibly because of a bad config.g.

          See https://docs.duet3d.com/User_manual/Troubleshooting/Duet_wont_respond

          Note that putting the firmware on the SD card does NOT flash the firmware to the board. You need to do one of the following:

          • if you can connect to DWC over WiFi: upload the firmware in DWC for automatic installation
          • if you have functioning firmware on the Duet but no network connection: have the firmware file on the SD card and send M997 via USB
          • if the firmware has been deleted from the Duet: flash the firmware to the board using Bossa

            = I tray bat unfortunately is same situation

            • if you can connect to DWC over Wi-Fi: upload the firmware in DWC for automatic installation
              = The Wi-Fi is not working (the LED near the Wi-Fi antenna is not lighting)

            • if you have functioning firmware on the Duet but no network connection: have the firmware file on the SD card and send M997 via USB
              = The device not appear in the Device Manager at all. Not possible to send anything 😞

            • if the firmware has been deleted from the Duet: flash the firmware to the board using Bossa
              = Please explain more about Bossa. Is possible to "flash the firmware to the board using Bossa" without USB connection?

            Thank you Zsolt

              without the right hardware which is expensive, no

                @szilveszter-zsolt What OS are you running on your PC to connect to the Duet? Windows? What version? Newer versions should detect the Duet, or the Bossa port (if firmware has been deleted) automatically. Older versions should show a port, but it may not be identified, and will need the device driver installed. MacOS and Linux should see the port without using a driver. See https://docs.duet3d.com/en/How_to_guides/Getting_connected/Getting_connected_to_your_Duet#install-drivers

                Are you sure your USB cable is a data cable? Many are just charging cables, so try another one. Make sure it is fully plugged into the Duet.

                  • What OS are you running on your PC to connect to the Duet? Windows? What version?
                    = we tried on 4 diferent computers;
                    -Windows 11 Home, version 21H2, OS Build 22000.978
                    -Windows 10 Home, version 21H2, OS build 19044.2006
                    -Windows 10 Version 10.0.18363.2274
                    -EndlessOS

                  • Linux should see the port without using a driver
                    = the device not appear at all on the computer with Windows or Linux

                  • Are you sure your USB cable is a data cable? Many are just charging cables, so try another one. Make sure it is fully plugged into the Duet.
                    = we tray many cables (we use them for data transfer)
