Hi Frank,
Thank you! I realized the headless nature after I posted 
I did get it to boot by going back to otp-22 and v1.11 on nerves_system_rpi0 so I can continue to learn. On the latest release, I get timeouts trying to ping nerves.local and the blinky leds don’t flash as they do with firmware built on the earlier release. Once I can debug things a bit better I’ll report back. I’ll check the links you provided and appreciate your help!
