Well, I'm having no luck with my Orange Pi. I seem to find no way to install something on an SD card that can boot.
I tried with the official Debian and Ubuntu images from the Orange Pi site. And the best I got was a partial load of Debian, but that was all. I tried Armbian, and got a blank screen.
The BE image gives me a black screen too.
I tried different cards (class 10 in 8GB and 32GB, class 4 8GB, 32GB Ultracard), different ways to mount the cards on my Mac (USB-A reader, USB-C adapter) and different flashing programs (Balena Etcher, ApplePi Baker) to no avail...
I don't know if I'm doing something wrong or if my board is toast, so I can't report a thing.
The only thing I can mention is that I'm not sure if the only step I need to do with the firmware is flashing the image to an SD card or I'm missing a step, because when I burn the image I only see demo software there, and no BOOT image or kernel (Am I missing a step? I guess it's highly probable).
I'll try my old Mac that has an integrated card reader (than my son uses now) to see if I can flash a card that works.
Very disappointing. Sorry I can't be of any help right now...
Edit: I'm buying the official power supply... it seems that the board may not be reliable with a 5V 2A normal USB power supply. Let's hope it's just that.
