Unknown command 'saveenv' error in U-Boot

I have a prebuilt image of the U-Boot. I can change the configıration using the setenv command. But, I can't save the current environment variables as the saveenv command is not recognized by the U-Boot. Also, there is no command called saveenv in the help list. U-Boot version is 2020.01. Other things such as booting works well.

The reason is simple. The prebuilt image was compiled without support to the saveenv command. If you have the chance to recompile the U-Boot, you can find it in menuconfig screen. Just go to the Command Line Interface -> Environment Commands and enable the saveenv.

I guess that there isn't an alternative way to save your current environment. You may want to search more on it.
