I don't know when I did the last u-boot update.
At least I kept it when updating from 13.0 p-something to 13.1.
However, in the meantime I did an update (with the arm64 package content)
and now the screen stays black.
Not sure when I will find time to investigate.
At least I'm happy that I didn't update one of my Pine64 first.
