Ok, so “Missing Partition Table” error message aside, older versions of Firewolf do in fact boot up properly, but the newer version does not. It would be helpful to know if there are other users who are successfully running the latest version, and what hardware they are using, in addition to how they flashed the image. Perhaps there is an underlying issue with the latest version, or, it is more critical of what type of hardware it supports, or the manner in which it is written.
Do they have a Forum or any community of their own that can verify / validate those hypotheses? Thanks.
