What is the best way to expose a custom uboot version (we have an internal version number for our release build of uboot). WOuld be even better to also expose a build timestamp.
I have tried using the compiler command line however this worked fine when programming with Mfgtool but I found when upgrading uboot this sometimes would not be updated (Weird I know).
As I am a bit of a newbie I may be missing something. I used the u-boot.imx file to create a full 2MB file and write that to the u-boot partition to ensure any other data is erased. Not sure if other stuff is saved elsewhere.
Note: we are using uboot 2014.04 and Linux 3.14
