As you may know, Snappy Ubuntu Core is Canonical’s Ubuntu system for the Internet of Things devices and aims the single-board computers and embedded devices.
Recently, Canonical has released the second Snappy Ubuntu Core 15.04 image, bringing BeagleBone-Black specific enhnamcements. The official announcement:
“Special attention for BeagleBone Black users: since we can’t yet update the bootloader during our snappy update process (planned in our backlog), we recommend you to do a clean flash with the latest image, since it incorporates a new u-boot and also a new way to set/save the environment variables used by Snappy. If you are using the previous stable version, the bad side effect is that rollback might eventually fail (as a result of a file system corruption issue),”
