You can start here by reading the provided documentation: http://git.denx.de/?p=u-boot.git;a=blob;f=doc/uImage.FIT/signature.txt;hb=HEAD There's also a ELCE 2013 presentation by Simon Glass: http://events.linuxfoundation.org/sites/events/files/slides/chromeos_and_diy_vboot_0.pdf And a paper by Jagan Teki from the U-Boot Mini Summit http://www.denx.de/wiki/pub/U-Boot/MiniSummitELCE2013/U-Boot_verified_RSA_boot_flow_on_arm_target.pdf The mailing list is surely the right place for further questions ;) Cheers Detlev -- There are two hard things in computer science: cache invalidation, naming things, and off-by-one errors. -- DENX Software Engineering GmbH, MD: Wolfgang Denk & Detlev Zundel HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany Phone: (+49)-8142-66989-40 Fax: (+49)-8142-66989-80 Email: d...@denx.de _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
