I'll read up on ground issues. New thing to learn.
Been running 15 hours now without a hiccup...
Topic: Canaan controller (Ras Pi 3) freezing randomly (Read 141 times)
Thanks. I have it on the same strip as the miner... Although I thought that maybe it should be different due to variable power draw.

Flakiness on an Rpi is usually power supply issues or bad usb cable supplying the power, but I think you are realizing that yourself. Make sure your pi adapter is on the same power strip as the miner's power supply to avoid ground issues as adapters typically don't have a 3rd ground prong.

It was a 2.5A charger - but it was from a Cana kit - and plenty of people seemed to have issues with those. I have a nice reliable 2.1A tablet charger on it now. 12 hours in and not a single hiccup.
I did add a script to check the ethernet connection periodically and reboot if it drops because that seems to precede the lockup.
So far - so good.
Thanks for the responses fanatic26.

No the rest of the SD is blank, its an 80mb image. You shouldnt have to do anything fancy. If you had a weak power supply before that may well have been the freezing problem. Minimum 2 amp because those AUCs do pull a lil bit of power.
Thanks for the reply.
I did that and the lockup still occurred. Do I need to format the remaining partitions on the Pi's SD card that appear to be unused?
I've now switched the power supply to another 2.5A adaptor. So far running 7 hours without a hiccup. We'll see how it goes....
I sure wish I could find log files thought.. Any ideas?

Just re-image it. Takes 30 seconds and will save you all that time troubleshooting.
My controller has frozen twice in the last 24 hours (new setup). I have the latest build.
Any suggestions on where to go to start diagnosing? No significant error cores shown. I can't find any logs in /sys/log on the Pi.
Thanks!
