New user of a Rock64 board, I've tinkered with a RaspberryPi and BeagleBone before but wanted something to set up as a home media server.
I flashed the SD card with an "Armbian_5.42_Rock64_Ubuntu_xenial_default_4.4.124" image and it worked perfectly fine at home, connecting to my network, etc.
However, I took it to a new location and it straight up refuses to boot. I've tried it on several displays and with several HDMI cables. It hangs for a solid 30-45 seconds after initiating boot with a black HDMI screen, and then turns off and back on dumping a log citing either spinup shutdown errors or a temperature shutdown on Core 0.
I've flashed a separate SD card with the same image as well as the stretch image off the main Armbian page and both of them work for a short while but then proceed to crash seemingly without change ~24 hours later.
Is there a large chance my board is simply intermittently dead or is the Rock64 known for being extremely picky with HDMI cables/monitors at boot?
Edit: Got it home to my original setup and I have no dice there. I'm at a loss - everything seems to work perfectly with the board after flashing but only for a day or so, then it gets stuck on boot. At this point I'm keen to put it down as a defective board, I'm not sure what else it would be after trying different images, SD cards, HDMI cables, and monitors.
