I am Stumped and looking for clues. Got an older tinkerboard with embedded board via c7 cpu and am unable to get multiple live distros to boot. All have been 32 bit as needed for this cpu. All end with a blinking cursor after going thru the boot process. errors received have been unable to init mce device, and long haul option not enabled. Furthest I got was with rapsberry pi debian desktop, which would let me enter install mode and actually installed on system hard drive, but after rebooot, same thing. Back to blinking cursor. Anyone have any clues, or path for diagnostic ? I have gurggled it but came up nill there too.
