Georg, I had a similar problem, if I understand your question correctly. We have a product that used to use ispLSI2064 devices, and then we could only get the 2064A variant. Our programming software wouldn't work with it, as it detected the wrong signature. We were using an old Daisy Chain Download software for DOS, as it was only used in the production area, for final system programming on an old 386 PC. Anyway, an email to Lattice sorted out the problem - the text from them follows:
------------------------ Hi Steve, The 2064 and the 2064A are the same functionally but they have different programming algorithms. So in order to program these new devices you need to download the newest software ispVM System 8.2.2 if you like the ISP Daisy Chain Download software. Or you like ispVM System go for the ispVM System 9.0.1 Hope this helps -------------------------- I can't remember the exact process for programming the new device, but it is very straightforward, and no JEDEC changes were required. As they say, hope this helps.
