Anyone found a fix to the GAL22V10D issue ? I updated to 6.17 but that has made no difference. Also, re-installing the first version of the software didn't work as it doesn't seem to like the later firmware in the programmer. Any way to roll everything back ?
I think I have fixed the issue...
I am using a GAL16V8D and tried programming it & got the issue as described earlier in this thread. So what I did was :
1/ Erased the GAL, read it back into code memory & confirmed all bits="1"
2/ Loaded into code memory my .JED file (I took screen shots of each page of the program for later checking)
3/ In the Options section unchecked the "Erase before" and unchecked the "Verify after"
4/ In the IC Config section unchecked the "Encrypt"
5/ Programmed the chip, X5 times; one after the other
And that seems to have fixed it. This afternoon I'll put the GAL onto a bread board and wire it up and check the logic. But to check that my experiment has worked. I started the minipro s/w & programmer from fresh.
1/ Filled the code memory with zeros,
2/ Read in the GAL chip into code memory
3/ Compared every page of the code memory with the screen shots of the .JED file I took earlier. EVERYTHING MATCHED
4/ Also did the normal minipro Verify option & that passed too.
Maybe X5 programming was more than was required (possibly X3 would work). Could someone else try the above & confirm those steps works for them too?
Fingers crossed we have a fix!!!!
