Hi,
I have a beaglebone black rev C with debian preinstalled. My BBB runs just fine with debian, however I wanted to test archlinux.
I created a sdcard with arch linux according to http://archlinuxarm.org/platforms/armv7/ti/beaglebone-black.
My BBB is powered by the 5V line. Other than that only ethernet is connected, the sdcard is of course inserted and I connected a USB to UART cable to the BBB.
I hold the S2 button while powering it up and the BBB boots from the SD Card:
