WARNING: Image format was not specified for 'buildroot/output/images/rootfs.cpio' and probing guessed raw.
         Automatically detecting the format is dangerous for raw images, write operations on block 0 will be restricted.
         Specify the 'raw' format explicitly to remove the restrictions.
