As a warning, don't watch if you are a dev and feel burned out. If not, it is a funny one 😆

Well…. I say to myself that I can debug basic electronics issues but then I am looking at two ( not insignificant value ) boards fried in front of me because someone somewhere decided to replace a barrel plug with a usbc connector 😥
The output of that „charger“ is a fixed 12v 3A and that is evil as 12v qc devices will happily use that but it really, really messes up with any board that expects 5V and has a basic lipo charging circuit.
I spent half a day thinking about surges and improving charging in and out protections ( I believed for an embarrassing amount of time the problem was live connecting a lipo cell that is charged too low ), while in reality I had pushed 12v onto the poor things…
Im going to start adding labels to all usbc chargers I have around, in memory of those boards ❤️🩹

@sven does this mean you have to fallback to reverse engineering/kernel auditing ? or is there a path for m1n1 to function as normal ? I guess it is too early to say… but would certainly prefer the hypervisor path..
Keep up the good work and community progress !
