I am using jffs2 with summary support. But size of file is increases by around 10 MB after applying summary to jffs2 file.
We are using nand of 64MB having 16KB erase block size.
mkfs.jffs2 --pad --eraseblock=0x4000 -l -n -d ROOTFS_PATH -o outputfile.jffs2
sumtool -n -l -e 0x4000 -p -i outputfile.jffs2 -o outputfile-sum.jffs2
size of outputfile.jffs2 is 31 MB
but size of outputfile-sum.jffs is 42 MB
Please tell me why there is huge increase in size with summary
