Hi. I have a Beaglebone Black, I had the same issues as here getting started: https://community.victronenergy.com/questions/169612/-1.html but have managed to get it working and upgraded online up until version 2.73. But i am unable to upgrade any further than that, whether i try via the online update or via an swu on the sd card. Is there any special reason why?
FYI, it is a rev A5C model.
Any help would be appreciated.
