            AFAIR I used this guide to figure out the right gpiochip index. You can further diagnose why DCS cannot connect by launching it with the --log-level debug parameter.

              @jpomo10 Turn on debug from the command line or the "LogLevel" in config.json

                  Hmmm. Your SpiFrequency is actually on the low side. Try increasing it to 2000000 (2MHz)

                    @jpomo10 Check the SPI connection. This error message indicates that DCS could not receive any data over SPI.

                      OK, I increased SPI to 2MHz but no change.

                      To rule-out hardware problems, I set-up a raspberry pi according to the instructions in the getting started guide.

                      I was able to connect to the Duet3 (thermistors and endstops were reading correctly) but the Duet never responds to gcode sent through the console. e.g. M122 just hangs forever with no response.

                      I had the exact same problem with the Jetson before I did my fresh install.

                        Do you have RRF 3.0 (non-beta) installed on the Duet 3? If yes, please share your config.g.

                            @jpomo10 Don't downgrade, the recommended RRF version is still 3.0. I just tried to use your config.g on my Duet 3 / Raspi and I can still execute commands when config.g has been processed. Also make sure the diag LED on the Duet 3 blinks when powered on.

                            If the error message in the DCS log remains "no header" then I can only say that the Jetson does not receive any SPI data. Perhaps it's best to check your SPI connection once more.

                              @jpomo10 are you using the original 26pin to 40pin cable provided with the Duet3 or did you make one of your own?

                                Thank you for testing my config.g on your set-up.

                                For what it's worth, I've now tried this with a Rasp Pi running DuetPi & a Rasp Pi running Rasbian.

                                In both cases, I can connect to the Duet3 but cannot send gcode through DWC. That's more than I can say for the Jetson Nano, since it will not connect to the Duet at all, so I'll adjust the SPI frequency some more, as you suggested.

                                I also reflashed with the latest stable release of RRF 3.0. I used the binary file called "Duet3Firmware_MB6HC.bin". Communication with the board through YAT seems fine.

                                @gtj0

                                I'm using the original (26 to 40pin). Just to make sure I didn't somehow damage it at some point, I'll make a replacement.

                                UPDATE: Swapping the cable didn't make a difference

                                  I'm beginning to think bad cable or bad Duet3.

                                    @hanshogeland and I were just chatting about upgrading a Nano so...

                                    Here's the latest device tree overlay file for the "b00" version of the Nano.

                                    • Download the file to "/boot" removing the ".stl" extension.
                                    • Run /opt/nvidia/jetson-io/jetson-io.py from a command prompt
                                    • Select "Configure Jetson for compatible hardware"
                                    • Select "Dual SPIDEV"
                                    • Select "Save and exit without rebooting"
                                    • Double check that a new "Dual SPIDEV" entry was placed in /boot/extlinux/extlinux.conf
                                    • Edit or move the entry as needed.
                                    • Reboot

                                      Thank you verry much!

                                      *Updated this post, since I hade the wrong config for the ready pin so Iǘe changed to pin 13 as it should be.

                                      I have ran the .py and verified the .conf however I get an error starting the DCS stating:

                                          @gtj0 This is really odd. I'm getting the same error now. Should have it fixed shortly.
