Xo and I have been using SF100s with AST2500 EVB.  It works OK.  The main gotcha seems to be that after writing to the flash with the SF100, it is left in a state that the AST2500 can't seem to boot from.  Power cycling fixes it.  I haven't spent the time to investigate further.

We have been able to use the tool to recover our systems.
We also had to power cycle the boards after flashing.

Yes. It works pretty well from a raspberry pi. I also have used a
Flashcat programmer.

You should make sure that the board is not booting from the flash
module. For that you need to unselect the flash chip, CS0 on header J44.

and one of your board perhaps. With details of what is around the
flash.

Will send some photos if we ran into any problems.

Thanks again,
Shay
