Rev B vs Rev C shouldn't matter.. I don't think I even have a Rev "B".. A6A, B, to C* was done very quickly at CIrcuitCo at that time.. https://elinux.org/Beagleboard:BeagleBoneBlack#Revision_B "This version moves to the AM3358BZCZ100 processor as we are no longer able to get the limited production version of the AM3359AZCZ100." I'm assuming the AM3358 had the pru enabled.. Regards, -- Robert Nelson https://rcn-ee.com/
