Hi,
I moved over to JFFS2. I created a jffs2.img file using mkfs.jffs2, loaded that
file from boot loader into flash and all worked fine.
I want to know is any way to create a empty JFFS2 file system from ecos
application itself rather than uploading the file from bootloader.
If(mount of JFFS fails) go and create empty File system
else continue further.
Thanks & Regards,
Ramgopal Kota

There's a fundamental problem here. The FAT filesystem is intended to
work on a _disk_ device using the eCos disk I/O layer, not on a raw
Flash device. The JFFS2 and ROM filesystems will work on a raw Flash device.
