Using pic to program spi flash
PostPosted: Fri Mar 28, 2008 7:09 pm     Reply with quote
I have a couple motherboards that were given to me because of bad flashes. These boards use spi flash chips, mainly sst25vf080B and mx25l8005 chips. These are low voltage parts.

I searched for a commercial spi programmer and the cheapest are several hundred dollars.

So I have some pics , 18f4580, 16f877a and was thinking of making a programmer to program these bad bios chips.


I am thinking of using the pic to interface to a host pc via serial port and then upload the program via a terminal program to the pic, with the pic programming the flash via spi.

Has anyone done this or something similar ?
Potential problems or pitfalls I should look out for ?
Just looking for tips or pointers.
Thanks
