I tried that but it is an EFI partition not an mtd partition. To my understanding, only mtd partitons will be split into rootfs and rootfs_data on boot. This does not hapen. I need a way to tell the system that /dev/mmcblk0p1 is my overlay FS. Is there a possibility that I can somehow tell fstools which fs to use for overlay. Or which depencies are there for detecting that an device holds an fs for overlay?
Kind regards, André
