I assume I need to set some environment variable or pass more args to the bootefi command???  I feel like I'm really close now.

Hi Markus,

On which device / filesystem does the efiboot.plist or boot.cfg need to be created on?  I have the following options:

1) ld0a (mmc ffs root)
2) ld0e (mmc fat boot)
3) wd0a (sata ffs root)
4) wd0e (sata fat boot)

I saw your notes on the content of the elfboot.plist file but do not recognize the dk1 device. (wish I could find the documentation on the possible contents of these files)  Oh...looks like dk* is for a GPT disk...my disk is currently MBR I believe (partitioned by following the NetBSD 8.0 evbarm-earmv7hf sysinst instructions here):

Again, thanks for the hints.

George
