thumb‎ Embedded Linux Class by Mark A. Yoder


In this class we run The Debian Distribution on BeagleBone Black. Debian now ships on the eMMC of the Bone. Here's how to tell what version you are running and how to update it.

Finding the version of the running OS

Attach your Bone to your Linux host via the USB cable. Once it's booted, on your host run:

host$ ssh -X
Warning: Permanently added '' (ECDSA) to the list of known hosts.

bone$ cat /etc/dogtag
BeagleBoard.org BeagleBone Debian Image 2014-08-05

I'm running the 5-Aug-2014 version Debian. If /etc/dogtag doesn't exist, or is older than shown here, you need to update your image.

Updating your SD image

The Bone can boot from either the built in eMMC (either 2G or 4G depending on which version of BeagleBone Black you have), or from the micro SD card. For this class we'll be booting from the SD card. It's faster to flash, and if you mess up something it's easier and quicker to recover.
