Hi, I am working on TI OMAP3 platform and was looking to reduce the JFFS2 mount time (NAND).
I have selected CONFIG_JFFS2_SUMMARY, but not working fully, its giving ECC error (at end of this email) after add a new file in JFFS2. Without this option its working fine; but taking long time to mount. Please let me know if I am missing anything -http://dev.omapzoom.org/pub/scm/integration/kernel-omap3.git [*] JFFS2 summary support (EXPERIMENTAL) i.e. CONFIG_JFFS2_SUMMARY=y => I have created and flushed jffs2 image with summary nodes, as- sumtool -n -e 0x20000 -p -i rootdir.jffs2 -o rootdir-sum.jffs2 # mount -t jffs2 /dev/mtdblock4 /mnt JFFS2 notice: (640) jffs2_build_xattr_subsystem: complete building xattr subsystem, 0 of xdatum (0 unchecked, 0 orphan) and 0 of xref (0 dead, 0 orphan) found. # umount /mnt ==> I checked this multiple time and no issue. # # mount -t jffs2 /dev/mtdblock4 /mnt JFFS2 notice: (644) jffs2_build_xattr_subsystem: complete building xattr subsystem, 0 of xdatum (0 unchecked, 0 orphan) and 0 of xref (0 dead, 0 orphan) found. # vi /mnt/test.c (created a new file) # umount /mnt # mount -t jffs2 /dev/mtdblock4 /mnt mtd->read(0x1fb04 bytes from 0x8de04fc) returned ECC error mtd->read(0x9a74 bytes from 0x8df658c) returned ECC error Empty flash at 0x08df6588 ends at 0x08df6800 JFFS2 notice: (656) jffs2_build_xattr_subsystem: complete building xattr subsystem, 0 of xdatum (0 unchecked, 0 orphan) and 0 of xref (0 dead, 0 orphan) found. mtd->read(0x7bc bytes from 0x8df6844) returned ECC error Is there another way to fix the problem? Am I missing any patch or missing any configuration?
