twebb,
As far as I know Android root file system cannot reside on
jffs2 partition as jffs2 does not have support for memory mapped IO.
One workaround may be to create an EXT2 image for the Android root FS
and place it in the jffs2 partition and try mounting it as loop
device. A brief procedure can be as shown here:
1. create EXT2/EXT3 image for android root FS
2. store the image under the jffs2 partition in NAND (booting out of
NFS, mount MTD partition and place the image file)
3. Boot your device using NFS or ramdisk
4. After boot completes, mount the EXT2/EXT3 image as loop device
5. chroot into that mounted directory and run android.
NB: i've tried the above steps for an SD card formatted as FAT but
never tried this for NAND/jffs2 combination.
Warm Regards,
Anil
