Hi,
I created a 1MB partition to speed up the testing. Maybe someone can do the same tests and tell me if he sees the same results...
* under linux I erased the partition with flash_eraseall -j /dev/mtd/2 * then I mounted it with mount -t jffs2 /dev/mtdblock/2 /mnt * and created a file on the partition cd /mnt/ echo test >testfile * reboot linux * under u-boot I did a ls and got the following (DEBUG_DIRENT and DEBUG_FRAGMENTS in jffs2_1pass.c are enabled) Scanning JFFS2 FS: . done.

How can I manage it that the deleted testfile isn't displayed anymore? Is this a NAND specific problem?
Thanks. Jonas
