Success!

I have no idea why but all of a sudden it "just works"? I just dd'ed a new SD card, plugged er in.

This is the actual log prior to booting /bsd:

Code:

I'll pardon the oddly naval bootloader and this is exactly the depth I wanted. And it even looks for USB mass storage before settling with the SD card. Very promising!
NP. But that is well documented. Pi GPIO are 3.3v only and always have been.
Such is the folly of being a software nerd. I can't code myself a way out of not realising there might be a voltage difference lurking in the fine manual.
