Update on the Pi experiment.

So i got two running fine then added a third unit.

The issue i get is that just now i get mining at 20 minute intervals before the ML2's start to effectively start hashing.

I have tried 2 units and messing with the clock frequency but same issue.

Problem seems to be if the miner gets out of synch with the pool - so i get a steady 10-20 minutes now at about 4.3MH/s but after the 20 minute mark i have to reset which takes 2-3 times to get all three hashing (or two when i unplugged one).

I know the most common error is power. I am using a 7 port Anker 60W unit with only the 3 ML2s on it so i would have hoped this would be no issue. I have also tried with 2 rather than 3 with no impact unless it is the maximum draw per USB port that is the issue? For info the pot slots are vertical when tuning - running MLD of 768.

I will play with the pots now and turn them down a litle to see if this stabilises issues.

In the meantime is there a config option that allows a restart to happen when hash rate hits 0 or kH/s so i dont have to keep monitoring it?

thanks

Note: In the time it toook me to write this i have had to reset again!
