Thanks @Baozhu. My BBG didn’t come with a micro SD card (though README documentation alludes that it would). I was planning on using just the onboard 4GB eMMC.
Is there anyway to update the eMMC flash without requiring a micro SD card?
Also, is there anyway to run from an OS mounted on my dev laptop? This old post from 2014 suggests maybe:
For development purposes, don’t use SDCards. Rather use NFS to mount a rootfs on your desktop
