Unable to update to 3.4.5 from 3.1.1 On Duet2WiFi

Milke

Hello: I t

I'm trying to update my Duet2wifi card currently using version 3.1.1. I checked that on the website it is recommended to install version 3.2.2 first. I didn't find this version available on Github, so I tried to make a new SD card using version 3.4.1 and was unsuccessful. can anybody help me?

"The location where the firmware files are stored was changed. Versions previous to RRF 3.3 stored them in the ‘0:/sys/’ directory, but from version 3.3 they are stored in the ‘0:/firmware/’ directory. When you upload the version 3.3 files in an older RRF version, they will be stored in the /sys directory. Once RRF 3.3 has been installed, subsequent firmware uploads will cause the /firmware directory to be created, and the firmware files will be stored in there."

@Milke If you are on 3.1.1, the instructions say to update to 3.3, then a later version. Realistically, you don't need to; you can go from 3.1.1 direct to 3.4.6 (the current release version).

Download the 'Duet2and3Firmware-3.4.6.zip' from https://github.com/Duet3D/RepRapFirmware/releases/tag/3.4.6
Upload it to the Duet. As you are on 3.1.1, this will put all the firmware files in the /sys folder
Let the Duet update the firmware
Occasionally, updating the WiFi firmware fails, and you can't connect to the Duet. Connect using YAT via USB, and send M997 S1 P"0:/sys/DuetWiFiServer.bin" to update the WiFi firmware.
Connect to the Duet via DWC. Check that the firmware and DWC are on version 3.4.6.
Upload 'Duet2and3Firmware-3.4.6.zip' again. This will create the ‘0:/firmware/’ directory, and put all the firmware files in it. You can delete the firmware files from the /sys folder.
