I got some replies now:
Sorry for the inconvenience. I do not know that device so I cannot help you. In the future I’ll try supporting it.
As we only make hardware it’ll be up to the zeroshell project to update their image to work with the net6501. I haven’t tried myself so I can only rely on the topic you linked but it seems like something needs to be updated in Zeroshell.
Any suggestions anyone how to get out of this loop?
