Revision to Installing and Updating Firmware

David Crocker

* Take the SD card out of the Duet and put it in an adapter connected to your PC.
* Use Notepad++ or another text editor to put a semicolon character at the start of the M552 line in file /sys/config.g so that the main firmware does not attempt to enable the WiFi module at startup.
* Copy the versions of DuetWiFiFirmware.bin (or Duet2CombinedFirmware.bin) and DuetWiFiServer.bin you want to use into /sys on the SD card. They must have exactly those filenames, so if the files you downloaded had the version number included in the filename, then you will need to rename them.
* Copy the versions of DuetWiFiFirmware.bin (or Duet2CombinedFirmware.bin) and DuetWiFiServer.bin you want to use into /sys on the SD card. They must have exactly those filenames, so if the files you downloaded had the version number included in the filename, then you will need to rename them.
* Safely remove or eject the SD card and put it back in the Duet.
* Connect the Duet to your PC via USB. If you have any high-current 5V devices connected to your Duet (e.g. PanelDue with a 7" screen, or servos) then you will also need to supply VIN power; otherwise USB power should suffice.
* Hopefully you will see "Duet 3D Printer electronics" and you can proceed to the next step.
* If instead you see "Bossa port" then you have pressed the Erase button, and you will need to install new main firmware via USB. See Fallback procedure #3 higher up.
* If you see no port at all, go to [guide|2|what[guide|2|what to do if your Duet or Duet 2 Wifi won't respond].
* If you see no port at all, go to [guide|2|what[guide|2|what to do if your Duet or Duet 2 Wifi won't respond].
