Re: BananPi BPI-P2 zero (H3 chip) fails to boot

Hello,

replying to myself:

When I was working on narrowing down this issue, when I copied the
u-boot binary again from another PC, the board suddenly loaded U-Boot
and the NetBSD kernel.

I suspected an issue with the PC I was using first, but when I
repeated the steps, it kept working.

There are some issues remaining however, I will report them shortly.
