[U-Boot-Users] How to get the U-boot version string from with Linux?
Hi,
Is there a way to get the U-boot version string from with Linux? Can the version string be passed or stored so that an application running under Linux can read it?
Best regards, Robert McCullough

Dear Robert,
nice to meet you again here on the mailing list!

Yes. Enable the CONFIG_VERSION_VARIABLE option in your baord config file (include/configs/atc.h); then there will find an environment variable "ver" holding the version string. Make sure to run "saveenv" in U-Boot at least once so that this automatic variable gets stored in flash, too.
Under Linux, you can then use the code from tools/env/ to access the U-Boot envrionment and read that variable.
