Dear "Parks, Derek",

I have an c++ application that needs to display various versions of system components; u-boot, kernel, O/S flavor, hardware and software versions. I'm struggling with getting the u-boot version and ask for your help. My ideal situation is to have U-boot report (somehow) to Linux it's version number and have Linux store it in environment variables. Any thoughts?
When CONFIG_VERSION_VARIABLE is set in your board config file, then U-Boot will set the "ver" envrionment variable to the current version ID string. If you run "saveenv" at least once, then you can read this string from the U-Boot environment under Linux, using the fw_getenv tool / function provided in tools/env/ .
Best regards,
