Well, good news ....
After about a thousand or so i2cget commands and referring to Ericsson docs and to the other working cubes and issuing a hundred or so i2cset commands ... I was able to get all the non working DCDC's up and running again. The dies are hashing away fine once again =)
KNC definitely has some custom configuration of each DCDC going on =-P
I wonder if any registers can be tweaked in the DCDC's for further power effeciency .. I mean these things have hundreds of configurable settings lol! its nuts.
nice job, but I think maybe we need to get you working on some newer tech
haha, well I do have an L3+ headin my way late september. Im sure by then it will be worthless but w/e ... maybe Ill poke around on it =-)
