Okay again, I am convinced about the no-file-in-FAT state. So, just to be shure for the state OF partition placed after the MBR before 1st MBR partition: If I have 1st partition's start sector being 2048 I hafe plenty of room before this after the MBR. The barebox state OF partition should be in there and I could place it at reg = <0x300 0xfffff> because the MBR ends at 0x1ff and the 1st partition starts at sector 2048 ( 2048*512byte=1MB=0x10000), is that correct, is the reg addressing done this way? Of course a length of 0xfffff is far too much, just to get a picture. Also to transfer this to an OF partition in a MBR partition. The container partition reg = <0xc0000 0x40000> in imx6qdl-prti6q-emmc.dtsi seems to be directly going to below a MBR partiton starting at 2048th sector with size 256kB, correct? Thanks for your patience!
