Hi all,
I'm trying to program CPLD EPM3064 (Max 3000 family) with quartus and USB Blaster. The problem is that I can program when the CPLD is in Blank (without anything inside). But then, I can't do anything else. I can't erase or read or verify, anything. If anybody knows something about that... Thanks!Link Copied

Hi Martin,
Thanks for the reply. I read this post already, and also I read that there's this pin OE1 (high voltage pin during programming). I tried with my CPLD and I just broke it down. My test was put there 11V when I was programming. Regards, Albert- Mark as New

Hi Albert,
I'm sorry to hear it. I assume the reason is in putting of high voltage in inappropriate time during device programming. I can't imagine that you are able to put the voltage at the right time according to manufacturer pgm algorithm. I think it is a job for a device programmer such as Altera Programming Unit APU or the 3rd party programmers from BPM, Data IO, Elnec or System General. Regards, Martin
