I have a Orange PI PC Plus that isn't booting either from sd or emmc. I had really messed up some configuration, so I erased emmc. After I erased EMMC, I started to get this boot screen.
If I insert a sd card in with the latest Armbian, I get no boot screen, or activity at all. In fact, even if I format the card, and insert it into the OP+ it gets no boot activity. It is only after that I remove the card that it can then boot from usb flash.
I ended up writing the latest orangepiplus image to a usb flash drive, and am able to get it to boot via a flash drive. I did backup my microsd install a few months ago with clonezilla. When I boot via USB, and run armbian-config there are no options for EMMC now. Basically, I need a little instruction of how to to get the OP+ to boot from micro sd again.
