Ok, our boots look exactly the same on that level. I guess they must have changed the need for those files or something?
In the directories:
grub: there is one 1-kb file, “grubenv” that thinks it’s a text file.
dtbs: there are two sub directories of the 5.13.0 and 5.16.0 versions that contain the .dtb files in the freescale sub.
5.16 version directory contains the .dtb and its .bak version, whereas the 5.13 version directory contains only the .bak version.
5.16 version directory files were updated Wed, apparently when i tried to update, with a sad result.
