The one I tested is the one from the ChirpStack documentation. But maybe both can be used? If you provide me with the page where you found the “official” RAK image, I can look into that + do some testing and maybe update the docs.
Also, where does the compat_version number come from?
That number comes from the error message if you do not make that change.
The device is supported, but this image is incompatible for sysupgrade based on the image version (1.0->2.1.4)
it’s in link 2 that I included in the question, the zip file contains a bin of the first version of GatewayOS2, the other GatewayOS2 downloads only includes the rwi update
What I meant to ask is, on which RAK documentation page did you find the https://downloads.rakwireless.com/LoRa/WisGateOS2/History-Version-Release/WisGateOS2_2.0.1.zip link?
