You might be able to use an embedded JAM Player. AFAIK Lattice
does provide a tool to covert their fus map files into something
suitable for use with a JAM Player.
Lattice's ispVM might also be an option.

Hi,
I'm looking for some information on the proprietary ISP interface used
by Lattice (specifically in the ispGDS22 device)
I've managed to find a Lattice document describing the function of the
SDI,SDO,MODE + SCLK pins and the devices internal state machine, but
nothing on specifically how to get the fuse map /JEDEC file into the
device 'in-situ'. I've searched the Lattice website, but they don't
seem to give out this information readily.
Can anyone direct me to a suitable resource?
Many thanks
David
