TL;DR --> How do I boot my BBB (rev C) from a recent 2015 build of Angstrom 
(ideally one I don't have to compile myself)?

The latest Angstrom images for the BBB 
<http://beagleboard.org/latest-images> are dated 2013-06, and I want to get 
the latest version working on my BBB. I notice that the Debian images are 
much more recent, but I prefer the fast boot-time of the Angstrom distro.

I tried the following:

   1. From 
http://dominion.thruhere.net/angstrom/nightlies/v2015.12/beaglebone/, 
   downloaded:
      1. MLO
      2. u-boot.img
      3. systemd-image-beaglebone.tar.gz
      4. modules-beaglebone.tgz
   2. On my SD card:
      1. Create bootable FAT16 partition and copy MLO and u-boot.img to it.
      2. Create an EXT4 partition and copy systemd-image-beaglebone.tar.gz 
      and modules-beaglebone.tgz to it.
   3. Per this discussion 
   <https://lists.yoctoproject.org/pipermail/meta-ti/2014-August/005060.html> 
   on yoctoproject, I did NOT add any uEnv.txt or zImage file to the boot 
   partition, and I am expecting it to boot from the kernel images under the 
   /boot/ directory from systemd-image-beaglebone.tar.gz.
   4. After inserting my SD card and powering up my BBB, I see some 
   blinking lights, but no output from the serial port (tty01), and no 
   response to my attempts to SSH in.


I have a 2014 build of Angstrom from 3rd-party vendor Chipsee, which works 
on my BBB. With that image is included the following uEnv.txt:

bootargs=console=ttyO1,115200n8 root=/dev/mmcblk0p2 rootfstype=ext4 
> rootwait quiet ;
>
> bootcmd=mmc rescan ; mmc dev 0 ; fatload mmc 0 0x80007fc0 uImage ; fatload 
> mmc 0 0x80F80000 am335x-bbb-exp.dtb ; bootm 0x80007fc0 - 0x80F80000;
>
> uenvcmd=boot;
>

I don't know much about u-boot, or how to debug the boot process. I will be 
grateful for pointers there if that's what needs doing. I know some of the 
commands above won't work because the latest Angstrom builds use zImage 
files instead of uImage files. Also, I don't know how to choose the correct 
addresses for the `fatload mmc` command, if that's required here.

Thanks in advance for any help!
