Curious, has anyone updated cgminer on their SP20E to another version besides 4.7.0 that's in the 2.6.14 firmware?
Interested in this as well. Installed 2.6.4 on an sp31, no change to cgminer.
If you change the ExtraFlag setting to 2 for extranone and restart it switches over to cgminer 4.8.0 if that helps at all.
