Thanks For the answers! I knew about the uboot overlay but have not played with it yet, I added the EEPROM from older BBB capes in a copy-paste mode...
Is there any documentation on how to setup the uboot overlays? Just as a starting place for when I get back around to it. I got my boards back, I'm slightly off on the overall dimensions but the stacking connectors line up nicely. Like everyone else I had some challenges getting cheap stacking connectors but I'm low volume, 40 pin stacking connectors and a few seconds on the belt sander was cheaper to make them fit than finding skinny replacements.
