Of course mkimage is not the same version. When upgrade to a new
version of U-Boot, you also get a new version of mkimage.

Where would you expect problems?  You can build and test the new
version of mkimage before updating the U-Boot image on your target
board.

And you can keep the old mkimage tool around for reference as well.

This makes no sense. I doubt that your NAND flash has 16 kB sectors.

Also I seriously doubt that you need 128 kB for environment.

Please do not copy code without thinking.
