First, I successfully flashed the Angstrom dMMC image to the BBB but then I issues trying to get the BBB to work using Ethernet. Someone from support suggested I use Debian instead because Angstrom is not being supported any longer. I’ve been trying to flash the Debian eMMC image to the BBB with no success. The Debian image I downloaded from the BB site does not have the “flasher” embedded in the name and I cannot find it anywhere. It seems it should be readily available. I found the following instructions but I am really new to the BBB and to programing so I am getting lost in the how to . . .
How do I do the following? Where do I find the /boot/uEnv.txt? What do I use to edit it?
Flashing eMMC
To setup the standalone microSD image to automatically flash the eMMC on powerup. Note, img files with the words “eMMC-flasher” already had this enabled…
If you look off to the left, there will usually be “flasher” somewhere in the description. Or . . .
william@eee-pc:~$ ls backup/ |grep blank
BBB-blank-debian-8.5-console-armhf-2016-06-19-2gb.img.xz
Blank meaning these images are meant to flash the eeprom as well, For new boards, and cases where someone trashes their eeprom, causing the board to be put into a non bootable state. This image as hinted at initially will flash an eMMC.
After editing the uEnv.txt file my BBB is still not flashing. The LEDs come on and stay lit after only a couple of seconds as though it had been flashed. Any other ideas?
“burn” to sdcard, insert into beaglebone, and it’ll start flashing immediately. Takes less than 5 minutes as I recall. But the LEDs will flash in a cylon like pattern. then go solid once it’s about to finish. Once completely finished, it’ll power down completely.

Thanks.
oops right. This could be an older boot loader issue. So, in order to
boot from the sdcard, you may need to press, and hold down the boot button.
Which is at the opposite end of the board from the ethernet port, and a
little to the left, Only button on that side of the board . .
Anyway, heh. Press and hold the button until you see a blink pattern on the
LEDs, then you can let go.
I have the flasher image on the uSD card from the eLinux link, but when I hold down the boot button to boot, I do not get any indication on the 4 LEDs. Nothing, even after 1 minute of holding it down. I confirmed I can read from the uSD card-- on normal boot, I can read from /boot/uboot just fine, editing the uEnv.txt file and all.
I have an element 14 BBB (rev. c). Is it possible that has anything to do with why I can’t boot from uSD card?
In my experience, instead of relying on the indicator lights, I use a serial console cable to see the progress on a BBB Industrial. I use a console image to flash the eMMC and that works fine. This should translate to the other images produced by Robert Nelson.
