Dustin,
Invoke with ts9441_update. There's not flash enough memory on a
TS-9441 to restore 32MB of flash on the TS-7400.
There's only 2Mbyte on the TS-9441 for the code "image" so it appears
it is pretty much just the fastboot kernel and the initrd. The
original poster said "a complete image" and I took that to mean 32MB.
The details about TS-9441 came from its schematic... The chip, U6, is
labeled 2Mbyte Flash.
To perform the update you'd have to have do what ts9441_update does as
described in:
http://tech.groups.yahoo.com/group/ts-7000/message/4959
If you were to use those instructions you would put what you want as
your code into one of the files listed from the untarring of
update_9441.tar.gz. I've had to perform one of these updates to return
my TS-7400 to stock but don't know which file has the code for the
2Mbyte part and which has the code for the 2Kbyte SPI EEPROM.
Some errors in performing changes like this >could< break your ability
to use a TS-9441 to update a TS-7400 correctly. If an error is in the
code programmed to the 2KB EEPROM or the update itself you could lose
your ability to SPI boot with the TS-9441. As long as you have a good
TS-7400 you probably could still get the TS-9441 going after such an
error - Maybe someone at Technologic would be best to confirm this.
