Could someone give me some responses ..... what is the meaning for Empty Block and Marking dirty, why do I have Empty Block ???? jffs2_scan_empty(): Empty block at 0x0000fffc ends at 0x00010000 (with 0x1985e002)! Marking dirty The file system I created is very small size (5 MB) and the /dev/mtdblock2 size is around 30 MB It seems that JFFS2 scans the entire memory space and erase unmarked block jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x0100000c: 0xffff instead Who is supoosed to write the Magic bitmask ??? Why Jffs2 scans the entire memory space ? It is not supposed to end at the last address that we can find in the file system that I created with mkfs.jffs2 ???? Write clean marker to block at 0x016c0000 failed: -5 Newly-erased block contained word 0xffff0198 at offset 0x01000004 What is a clean marker ???
