The official release from the main-line U-Boot repository had a lot of changes as shown in the Statistics page, but the one’s that caught our attention most were the USB fixes and enhancements that allow the use of the USB Mass Storage Gadget as described in this post.
As always, we saved the previous production branch into a branch (production-before-20140922).
U-Boot > bootfile=u-boot.nitrogen6q ; run upgradeu
The full list of binary files for various boards and configurations is available here in our U-Boot on i.MX6 page.
Many thanks to all of those contributing to this project!
