      Hello,

      I have a Duet 3 MB6HC with a Raspberry Pi attached running RRF3.2 beta 2. I tried to update to version 3.2beta3 with:

      sudo apt-get update
      sudo apt-get upgrade
      

      But it stayed blocked on "Sending DWC update" or "Sending DCS update" I can't remember. After a few hours I had to reboot the raspberry. Now if I try to go to Duet Web Control I have the following error message: "Failed to connect to Duet, please check your connection (DCS is not started)".
      I tried to downgrade to 3.1.1 following this topic: https://forum.duet3d.com/topic/19257/downgrade-from-3-2beta2-to-3-1-1/9 but I got an error as well: "[fatal] Could not connect to Duet (Timeout while waiting for transfer ready pin)"

      Any idea of what I can do?

      Thanks

        You have two choices.
        Either setup a usb card to use the duet in standalone mode. In there you can downgrade the firmware to 3.1.1 and then go back to using the pi.

        Or you'll need to use bossa to sort out the firmware on the duet.
        If you've got 3.1.1 installed on the pi, downgrade the duet to that.

              I managed to connect to the duet via USB and YAT and the firmware version is 3.2 beta3 and it seems to work well.

              Version 3.2beta3 seems to be installed on the Raspberry too but the connection between the duet and the Pi doesn't works.

              Should I still try to flash the duet to install version 3.1.1 or run it in standalone mode or is there something I can do to restore the connection between the Pi and the duet?

                On the Pi side you might want to try preparing a new SD card with the latest DuetPi image and then trying to update to the unstable branch.

                        @chrishamm I think he's got 3.2beta3 on the duet and on the Pi, but no communication between them.

                        @Lucas Can you test continuity of your ribbon cable?

                        How do you have the Pi and Duet powered?

                          @Phaedrux the Pi is powered by the Duet via the ribbon cable and the duet is powered by a 24V power supply on the "Power In" connector.

                          I flashed the Duet to the version 3.1.1 and flashed the Pi again too and now it's working. I'll stay on the stable version for now.

                          I don't really know why the communication was broken because both the Duet and the Pi seemed to work fine on their own.

                          Anyway, thanks everyone for your help!

                            @Lucas said in Update to 3.2beta3 failed:

                            the Pi is powered by the Duet via the ribbon cable and the duet is powered by a 24V power supply on the "Power In" connector.

                            Pi3 or Pi4? Any peripherals? It's probably a good idea to power both the duet and Pi separately.

                              @Phaedrux It's a Pi3 and the only peripheral is the official raspberry camera. I didn't knew it's recommended to power them separately, I'll change my wiring. Thanks for the information!

                                @Lucas It was originally hoped that powering the SBC from the duet would be possible, and with the Pi3 it usually is, provided there are no high powered peripherals, but the pi4 uses more power than the pi3. And once you add a peripheral like a usb powered display all bets are off.

                                It would be worth testing with them powered separately at any rate.

                                  Hello,

                                  As @Phaedrux suggested I changed my setup to power the Pi separately and as expected it was still working perfectly.
                                  And then I saw that @dc42 released the version 3.2beta3.2 of ReprapFirmware and that one of the purpose of this release is to address communication issues with an attached single board computer. So I decided to give a new shot to the 3.2beta3 and... I encountered the same issue that the one described in my first post 😕
                                  The upgrade is stuck on "Sending update request to DCS..." for 25 minutes now and DuetWebControl is displaying this message: "Please wait while updates are being installed...". Usually this process takes a few seconds and I'm pretty sure that if I stop the upgrade I'll have the same communication problem as before.

                                  Here are the upgrade logs:

                                  sudo apt-get upgrade

                                  So before I reboot and flash everything again, do you want me to try something or get some logs?

                                    Once you update your Pi to 3.2-b3.2, you should be able to connect to RRF 3.1.1. But it's quite odd that you cannot connect to it any more when you update the firmware on the board via DSF. Can you attempt to flash the b3.2 binary manually via bossa and check if it boots then? Does the diag LED pulse once the new firmware binary is installed?

                                      @chrishamm Hi, I flashed the Duet to version b3.2 via bossa, the dial LED was pulsing but the communication between the Duet and the Pi was still broken. So I flashed version 3.1.1 to the Duet and now the communication works again even if the Pi is still on version 3.2-b3.2.

                                        @Lucas Can you please run sudo journalctl -u duetcontrolserver -e over SSH or from a local terminal when the latest firmware is installed and check what error is reported? It sounds really strange that it works with 3.1.1 but not with 3.2.0-b3.2.

                                          And for information it worked great with versions 3.2b1 and 3.2b2

                                            Very strange. I suspect you have a microSD card in the Duet that prevents the SBC from connecting. If that is not the case, can you connect once again via YAT with 3.2.0-b3.2 installed and post the output of M122?
