Creating a JFFS2 File System
The ADS Linux Bootloader Manual and Linux FAQs discuss creating and copying a JFFS2 file system to On Board Flash.
You can use mkfs.jffs2 on a PC to create the JFFS2 file system from a directory:mkfs.jffs2 -e 0x40000 -p -r dir > file
The 0x40000 parameter is 256k (2 chips X 128k block size for the Intel 28f640 chips).
The first time you mount the file system, you may see erase block error messages. These messages are inconsequential and should not occur again.
