Is it possible to add Erase Block Summary (EBS) informations to a JFFS2 filesystem without having to create a JFFS2 image and using sumtool? I am trying to speed up my JFFS2 mount time. Currently, I write my filesystem to flash using an NFS mounted root file system. To add the EBS information, I used mkfs.jffs2 to create a JFFS2 image and then used sumtool to add the EBS information to the filesystem and then copied the filesystem image to the flash. When I do this, the board will boot up but after I do a write, the board will lock up and u-boot doesn't even start when I power cycle the board. Thus, I would like to be able to add Erase Block Summary (EBS) information to a JFFS2 filesystem without having to create an JFFS2 image and using sumtool and see the behavior. Is this possible?
