The Yocto image also has an upgrade script (6x_upgrade) which can be
run from the U-Boot prompt through the 'upgradeu' command:
U-Boot > run upgradeu
The next question I'd ask is "why are you upgrading"? There are
some valid reasons, especially if you're running something that
pre-dates 2013-02-12, but I wouldn't make a practice of doing it
during each Yocto release.
We expect relatively infrequent updates to the boot loader,
and everything that's shipped in the past few months should
be adequate for most uses.
We do have some updates for boot speed upcoming (which enable
cache), but those haven't been pushed to the meta-freescale
If you're running on a Solo or Dual-Lite processor, you'll also
risk bricking your board. We haven't put any instructions into
Yocto to differentiate between the models, and it probably
doesn't belong in this project.
