Rapsberry Pi 1 controlling an Avalon AUC3

[ccgllc]

Hi all.  Received my first batch of Avalons today.  I went to set up (3) strings:  String 1 was headed by a pi 1 with a single 821 on it.  String 2 was headed by another pi 1 with (5) 841s on it.  String 3 was headed by a Pi 3 with (5) 841s on it.  Once I found real data cables to use with the AUC3s (and found out just how many charging only cables I have!), the Pi 3 unit came up just fine.

The (2) Pi 1 units had AUC3's that were mostly blue but slow blinking green.  e.g.  They were more-or-less always in setup mode and resetting as soon as they came ready.  The Avalons behind those two Pis remained idle (yellow light).

I moved the AUC3s from those Pis over to the Pi 3 and confirmed the AUC3s were fine, the cables were fine, and that the miners were fine.  Currently running all (11) Avalons off that single Pi 3.

Curious if anyone knows what the problem was driving the AUC3s from the Pi 1s?  I thought perhaps insufficient power supplies to drive both the Pi 1 and the AUC3, so tried a 2.4 amp one - but had no change.

Any other ideas?

Did you load the correct firmware onto the Pi-1? RasPi 1, 2, & 3B all use different firmware you can get from the Canaan site.

Yes.  The correct firmware was loaded.  That said, I have some time today, so will try that again.

Update:  Thanks for the sanity check.  Reflashed the SDHC cards and both came up fine.  Not sure how I got those flashed with the wrong version... its not like a full size SDHC card would fit in the Pi3, but somehow I manged.
