Most Vendors are already completely overstrained w/ anything software-related. A good reason why we should try to get rid firmware, as much as we can. It's really sad. A *decent* vendor would just provide a clean DT and (actually matching!) schematics. But that's really hard to find, these days :( --mtx -- --- Hinweis: unverschlüsselte E-Mails können leicht abgehört und manipuliert werden !
