Nano Pi Neo Core 2 freeze

Recommended Posts

Hi I have strange problem with my nano pi neo core 2. The device was working a few days then suddenly I lost my ssh connection. I used serial port to communication to see what happened and I get reply below. The last line it is a Error so I should reset my device. I did it several times and the result is the same. I'm not specialist but I supposed it is something wrong with eMMC memory because if I insert SD card with armbian it starts normally. Anyone have idea what was that, what happened. My nano pi shows week light of red LED.
