This requires that the user can write the current version to "ver" from a command.
This will not work. No matter what the user sets "ver" to, it ill be overwritten when U-Boot boots.
If such a command exist, You can read the version from your bootcmd, and send it as a parameter.
Yet another alternative:
A command "sync_version" 1) checks if "ver" and 'version' are identical 2) sets "ver" to version, if not the same. 3) saves the environment
With this, the user can select if/when to sync
Ideally this should be in a script "reboot_cmd" which gets executed at every reboot before anything else is executed.
Is there such a facility?
