I have installed Ubuntu in the eMMC of the BeagleBone Black and Debian “bone-debian-7.8-lxde-4gb-armhf-2015-03-01-4gb.img” on the SD (non flasher).
If I remove the SD card only I am able to boot from the eMMC. If I boot while the SD is plugged with no switched pressed the BBB boots by default the SD image. Also if I boot (connect power cable) while holding the boot switch still BBB boots from the SD card.
Why does this happen? Has anyone else had this experience?
