Working at application level (userland)

The same procedure and results can be directly used in case of parallel NOR Flash, always

assuming JFFS2. Note that there is no dependency on the specific SPEAr embedded MPU

or evaluation board.

For evaluation boards provided with NAND Flash, there are two options: JFFS2 and

YAFFS2.

In order to rebuild a JFFS2 root filesystem for NAND, the procedure to be run on Linux host

PC is as follows:

$ mkfs.jffs2 -n -p -l -s 0x200 -e 0x4000 -r $BUSYBOX/_install/ -o

rootfs_nand_smallpage.img

In order to rebuild a YAFFS2 root filesystem for NAND, the procedure to be run on Linux

host PC is as follows:

$ utils/mkyaffsimage 2 $BUSYBOX/_install/ rootfs_nand_smallpage.img

For all cases above, the root filesystem contents are assumed to be stored under the path:

$BUSYBOX/_install/
