[beagleboard] How to boot from microSD card image, not from the onboard flash?

I have a new BBB (Beaglebone Black, rev C). I just installed Robert Nelsons's latest Ubuntu image on a microSD card (https://rcn-ee.com/rootfs/2017-07-14/microsd/bone-ubuntu-16.04.2-console-armhf-2017-07-14-2gb.img.xz). The onboard eMMC has the default Debian that came with the BBB. I don't re

Re: [beagleboard] Re: How to boot from microSD card image, not from the onboard flash?
