Two things. First, I have had success with my bitbaked images. After I grabbed my console serial cable from work it seemed my boot was failing to find /dtbs/am355x...dtb for the bbb, so I created the folder on the boot partition and added the dtb file and it has since worked.
Second, while netboot is cool, it's not quite as cool as fastboot. Here is a fan review and tutorial for Android BBB<http://wiresareobsolete.com/wordpress/2013/11/fastboot-on-the-beaglebone-black/> , AM335x eMMC booting<http://processors.wiki.ti.com/index.php/AM335x_Android_eMMC_booting#What_is_fastboot.3F>doc by TI, and the succinct fastboot protocol here<https://gitorious.org/rowboat/bootable-bootloader-legacy/source/076ef94d61f349f7cf0fe776e60456d8f232cca5:fastboot_protocol.txt> . As it happens, I have just connected to u-boot from linux host using fastboot. Next steps are to see if I can boot or flash an Angstrom image over USB.
