@bartekp See https://docs.duet3d.com/User_manual/RepRapFirmware/Updating_firmware#required-files

In-App programmer (IAP) binary - This file is needed on the SD card and does the job of programming the firmware. There is a specific version for each Duet board. They don’t change with every firmware release, but new versions often accompany major firmware releases. You will get a message if it is missing, with the filename it expects, and (in DWC 3.3 and later) the location it expects to find it. If it is missing, check the firmware version your Duet is currently using, and download the iap file from the matching firmware version on the Duet3D Github repository. If the IAP file isn't included in the 'Assets' list of that firmware release, it should be in the .zip file for that release.

If this is for Duet 2 WiFi/Ethernet, you need the 'Duet2_SDiap32_WiFiEth.bin' file from the firmware release in the firmware folder. If you're updating from an old version RRF (before RRF 3.3), you may need to put it in the sys folder.
