Programming non-EPCS serial flashes?

I've got a non-EPCS serial flash hooked up to my Cyclone, and I'm wondering if Altera provides some way to use any of their flash programmers with generic flash chips. I heard noises a year ...

hi mike,

we use the st micro serial flash because its a drop in replacement for the altera. (m25p64 for the 64mbit)

the point for your problem is that the st micro parts are well documented and you may be able to create an emulator layer.

Yes, Altera EPCS parts seems to be no more that "Rebranded" M25P ST parts. You can convince yourself by comparing EPCS datasheet and M25P datasheet (command set).

The only different thing is device code (but it seems logical, no ? http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/biggrin.gif )

Another thing : I don&#39;t know if quartus programmer check this ID code before programming. So I fear that Quartus programmer will reject non Altera devices. But I&#39;m not sure . Anybody knows ?
