I have a M5 that I’ve used for about a month. When I power the board now it does not boot. I get a solid green, blue and red led light. Before, the green light would go out and the blue would start flashing. Before this started happening I had flashed the emmc storage with an Armbian image that I got from here: https://www.armbian.com/bananapi-m5/ What does the solid green light mean?
