What type of file system do you want? If a non-persistent read-only fs
is required you could use the romfs. The image is created by using a
tool that converts a directory structure into a single binary image (on
the host computer) that can then be linked with the application binary.
A RAM FS is also available for creating files at runtime, but I do not
know of any way to generate an image like the romfs.
We use the JFFS2 file system and have writen a dummy flash driver that
points to a location of static ram. JFFS2 uses a tool (like the romfs
one) to generate the starting image, and the filesystem can be writen to
at runtime.

hello........
I dont have an FLASH memory.... is there another method with
which i can do it...
only the way is hard code it to a file and include it...as the
included file will be a structure of field needed..... for eg........
like the rule....
struct rul rule[] ={{ 0xa50b810a,2000,0x911e810a,3000,"icmp",'y'},
{ 0x482e810a,21,0xc1e810a,20002,"ftp",'n'},
{ 0xbc0b810a,9000,0x9c0b810a,600,"678",'y'}};
but this isn't an efficent way....... do u hae any other idea regarding
this..........
Regards
Pai
