The main issue we face is what can we create to send out to our field
users to restore a completely corrupted flash memory chip on a TS-7400
board? I understand that there is only 2M on the 9441 board, but we
could possibly make a version of the 9441 that has much bigger flash.
Sending the unit back to Technologic is difficult, as these are
located overseas.
Any help is welcome!
Thanks.
