I got my M3 last year before christmas. But there is now way for me to get it stable to work. I tried every image that is available for download, i soldered a DC-Connector piggyback to the usb-connector, i tried with heat sink. No chance. My last try today was the android V2 Image. The M3 crashes with only red LED permanently on - with every image. Today after 30 minutes, sometimes after a couple of days. Please help me. I simply want to run a debian without gui.
The M3 does have a tendancy to overheat, they really should have fitted a heatsing to it.
Try fitting a big heatsync to the CPU, the bigger the better I did this on mine and it is quite stable now. But I don’t run any apps that are likely to cause a lot of CPU stress.
I would go with this image here BPI-M3 new image:bpi-m3 Ubuntu 16.04 Beta Mate (not the featured one in the thread but the hybrid I created). Read throught the thread to get an idea how/what to fix afterwards (kernel updates for example – ‘Team BPi’ still only provides a brain-dead way to apply these fixes but it’s wort the efforts).
