Hi!
I am currently working on installing a JFFS2 filesystem on an ARM
system, using a Samsung NAND Smartmedia device and 2.4.20 kernel from
montavista 3.1.
I succeed in mouting the partition and installing my filesystem in it
using the following commands:
root:/# mount -t jffs2 /dev/mtdblock1 /mnt
root:/# cp -r /usr/admin/* /mnt
My aim is now to create my filesystem using mkfs.jffs2. When mounting
the partition, I get ECC, CRC and magic bitmask errors.
root:/# mkfs.jffs2 -r /usr/admin -s 512 -e 16384 -b -o /dev/mtd1
root:/# mount -t jffs2 /dev/mtdblock1 /mnt
mtd->read(0x400 bytes from 0x0) returned ECC error
jffs2_scan_eraseblock(): Node at 0x00000000 {0x1985, 0xe001, 0x0000002c)
has invalid CRC 0xa026b584 (calculated 0xa026b184)
jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00000008:

0x5121 instead
jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x00000200:
0x0801 instead
etc.
It seems that the OOB data is damaged...
Do you have any idea of what happens?
Thanks in advance!

Direct output of mkfs.jffs2 to NAND is not working yet. Output to a file
and use nandwrite to store it on the FLASH
