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 project. 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. Regards, Eric
