Well just to be clear, are you trying to say that flashing via the SDKM always yields images that will work on multiple boards?
There seems to be some contradiction on another thread (Not able to run jetson-io.py - #14 by WayneWWW). What would be great is if nvidia states the steps for us to reproduce flashing of images that are able to work on multiple devices, e.g.
- Format SD card
- Flash on SDKM (which add-ons to skip/include)
…
For right now I would like to state that the only way for an sd card to work on multiple boards in my experience is to flash it with the official r32 images using etcher or dd, and not the SDK manager.
