size of ebs enabled image much bigger than original
Hi,
I wanted to test EBS for faster boot of my embedded system. I created a new rootfs with mkfs.jffs2 (mkfs.jffs2+sumtool from cvs today)
The image before sumtool has a size of about 3.7Mb. After sumtool it has 5,9 Mb
Submitted commands:
mkfs.jffs2 -e 8448 -n -l -r act -o image1
sumtool -e 8448 -n -l -i image1 -o image2
Is this "normal"?
Best regards
Peter

It is perfectly normal if the image becomes larger, but 60% looks too much... May be this is the result of small eraseblocks?

You are right. With 64K erasesize it gives about 3,7Mb -> 4.0Mb
Thanks
