i am a little confused now - i thought epcs16 & 64 are supported with nios ii version 5 ?[/b]

haven&#39;t heard of an epcs64; just the epcs1, epcs4, and epcs16. the epc4, epc8, and epc16 (note that there is no &#39;s&#39; in their part numbers) are altera passive serial configuration devices which expose the internal flash chip&#39;s interface bus so you can hook it up to a cpu; these are not active serial epcs parts nor cfi parts, thus they are not supported. cost us three days before we figured out why our epc16 and the cfi peripheral weren&#39;t talking to each other.

> it would be nice if they released the source for the slave programmer

are you referring to the source for the magic firmware_rom.hex? releasing just the protocol

used by the flash programmer would go a long way, no?

That along with any tricky mojo required to make it work (things like "after the clear flash command, the programmer should reset" or whatnot) would be all that&#39;s needed.
