I’ve been lurking here since last Sept while I’ve been playing around with my BBB, running a few different versions of Angstrom and Ubuntu off the SD card. And trying out different applications on the device. Now I want to flash the eMMC but I’m having trouble getting it to start writing the image into eMMC. It simply boots off the card. The image I’m trying to flash is RCN’s BBB-ubuntu-13.10-2013-12-17-4gb fwiw.
What am I doing wrong? I have a populated SD card inserted in the device. It’s the card I’ve been using to try out different OS versions so I know it works. I hold down the boot switch while I power it up via the 5v barrel connector. The power supply is 5V, 2A. I read one place where they suggested holding down the reset and boot switches at the same time when applying power. No luck with that either.
Any ideas? Any help is greatly appreciated.
Well "BBB-ubuntu-13.10-2013-12-17-4gb" out of the box was just "designed"
to run just off the microSD card... (no flasher in name)
So... To make it flash the eMMC, boot once and:
sudo touch /boot/uboot/flash-eMMC.txt
sudo touch /boot/uboot/run_boot-scripts
(this second one was removed in later script..)
then reboot... (it should flash... but that was 2013-12-17..)
Oh okay, I thought the flasher was burned on the device, but it’s part of the image then. Well that explains
me troubles. I don’t know where I got the idea the flasher was burned on the device but now I know - thanks.
Is there a better image to be using beside the one I have? I’m not committed to this one in particular. I need
something that will support a USB hub with a serial-usb adaptor and a usb printer.

Really, it's just a parameter (eMMC-flasher.txt) for the init script for
the board.. It then just set's up the eMMC partition and sync's the microSD
to eMMC via rsync.

That one should be fine, i usually push an update about once a month, so
that's now 2 releases old. Here's a link for one i just pushed a little
bit ago (just finished uploading), will be updating the wiki tomorrow..
after you dd this to the microSD, it'll flash the eMMC on first boot..
