Lucko and Mr. Teal,
...
What now is really needed next is that after cooling down the preheating restarts again so if my boards are interrupted from work e.g. network outage, they yould not resets. In fact I've also a problem with bfgminer. After a reset the /dev inode will change so bfgminer did not found them any more. So it will not restart the mining by themself :-( So preventing the device from reset will be very helpfull.
...
And it would be nice to see which fw is installed by the version number?
Cheers...
I more or less told all his to MrTeal and hi is working on it(I hope). He will not open his fw so we need to wait for him. But now that I have someone else saying that his board has the same problem only at different temperature he will probably be more sure it is not just isolated case...
I confirm this issue. I solved it installing cgwatcher and configure it to restart bfgminner every 6 hours - If this ocours only loose this minning time. Now i have a quite stable setup even using 3 boards with pre heating firmware.
