I run a 2.4.25 kernel (yes I know it's very old) on this board with mtd from 20041007 snapshot. I burn a jffs2 image on the nand with "nandwrite -j" (from nfs). All is ok and the filesystem is good but when I reboot the board or when I remove the power "violently", I get somes messages like this : /Empty flash at 0x009826d8 ends at 0x00982800 jffs2_get_inode_nodes(): Data CRC failed on node at 0x00cc0f90: Read 0x6e17981a, calculated 0x4614a389 /And I get one more message each time I reboot the board. But the filesystem doesn't seem corrupted. If I umount / before rebooting, I don't have one more error message at the next reboot. Here is my kernel command line (passed from uboot). Do I forget some mount options ? /Kernel command line: root=/dev/mtdblock3 rw ip=172.16.48.19:172.16.16.240:172.16 .254.254:255.255.0.0::eth0:off panic=1 / Do you have any idea about where the problem could come from ? Frederic. PS: sorry for my poor english.
