>Description:
Trying to boot NetBSD 7.0 armv7 image results in a failed boot. I closely followed instructions on NetBSD Wiki page for Allwinner A20, but booting fails after last line: "transferring control to NetBSD stage-2 loader (at address 40007800)".

BananaPi is connected via HDMI to a Samsung LED TV, that's why I cannot include a console output here, but here's a picture of failed boot where everything could be seen:

After that I get a black screen, sort of like it disconnects itself from TV.
BananaPi power comes from a 2A USB power adapter connected to power port, not OTG port.
>How-To-Repeat:
Boot NetBSD 7.0 armv7 image on BananaPi M1.
>Fix:
No fix, I also tried booting NetBSD snapshot images (I believe I also tried -current) from NYFTP but the outcome is the same.
