If that's the case, then you can copy the file to the stick as follows:
mount mtd:mfg -t jffs2 /mfg && cp /mfg/mfg.dat /media/hda1/ && umount /mfg
umount /media/hda1 ; sync
Nope. Not working. I assume I am supposed run the USB code I posted first. I tried with and without. Tried a couple different sticks. Will keep tinkering this weekend.
Result without initial USB code:
# mount mtd:mfg -t jffs2 /mfg && cp /mfg/mfg.dat /media/hda1/ && umount /mfg
cp: can't create '/media/hda1/': Is a directory
Result with initial USB code:
# insmod /lib/modules/2.6.30.10-motopia/kernel/drivers/usb/storage/usb-storage.ko
# modprobe usb-storage
# mount mtd:mfg -t jffs2 /mfg && cp /mfg/mfg.dat /media/hda1/ && umount /mfg
mount: mounting mtd:mfg on /mfg failed: Device or resource busy
