Hi. Sorry for a stupid question. When you get a DTB by using fdtoverlay, there is no way to know how it was produced later. Correct? For instance, this case: $ fdtoverlay --input base.dtb ovl.dtbo --output foo.dtb Once you get foo.dtb, you will never know whether it was assembled from base.dtb + ovl.dtbo, or it was directly generated from a single source, foo.dts. In my understanding, there is no room in DTB to record such metadata, and it is impossible to disassemble foo.dtb into the original components, base.dtb and ovl.dtbo. Please let me confirm that I did not miss anything. -- Best Regards Masahiro Yamada
