Hi,
so without knowing what the swappiness actually is I changed the value from 100 to 512.
Since then, I can't boot my Banana Pi M2 Zero.
Shortly after that, I remembered again: swappiness is the percentage of how often to use swap and not the maximum amount of storage.
Can I repair it inside uboot?
Can I plug the sd card into my PC and edit the files there?
Here is the log from the serial console. It's stuck forever after the last line.
