I have an Odroid-C1+ running some version of Armbian (I forget the details, exactly) - it's been happily working for a while, but recently that board went dead. I finally got a serial console on it, and captured the output below. Pretty clearly, something is wrong, and it being a cheap flash card, I bet the card itself is going bad. My real question: does anyone have a good suggestion how I can recover anything there is to recover from the SD card before setting up a new one? It's been long enough since I set up this device that I'd prefer not to start from scratch if I can avoid it.
I'm not much of a Linux guy (usually NetBSD/MacOS), but I do have a Ubuntu 16.04LTS VM I can use for mounting - but I'd love any suggestions how to maximize my chances of having something recoverable... Thanks!
