Can`t get a newly built Angstrom linux to boot and flash

In uSD with the image “BBB-eMMC-flasher-2013.05.27.img” you will find the build folder that contains the files that will be used in the installation of eMMC, the file that is executed for installation “/usb/bin/”, this file is executed by the service /lib/systemd/system/emmc.service.

Enjoy yourself
