I can't really advise there, I never use Pncconf.
However, what do you get if you set the step generators (etc) to zero?
I'm know that General I/O is available in free pins. Just the problem is that it isn't available in Pncconf

If I decrease number of stepgens then I had that pins available as general I/O

This may indicate a pncconf bug or a xml file problem
You might look at the working xml file vs the new ones
I do notice that my xml files use "Not Used" as the
secondary function tag for GPIO only pins but Chris's
files seem to use 0. Not sure if this matters or not, since if the
secondary function is "None", thats all you need to know...

Replacing "Not Used" with "0" solve the problem, at least with Pncconf. (I didn't test if real hardware work)

Pncconf uses the second number as a switch. mainboard GPIO is 0 meaning it can be changed from input to output.
sserial I/O uses 100 meaning it cannot be changed,
This allows me to use the GPIO routines for both types of I/O.
So that's why it matters

Hello...
Finally I have near finished electric box for machine.
Today I connect Mesa card and pc.
Well provided "custom" bit file doesn't work, but SVST4_4 for example work. All other data is same. I just configured simple 3 axis and try to start LinuxCnc.
With SVST4_4 program runs and seems to communicate witj card. But enslavko400 config give me error when I run LinuxCnc.
Any help?

Yes I do.
What a stupid mistake... I look all around and didn't see that.
Is it there maybe some tool to manualy toogle individual pins? (to check everithing before running.)
And how the output's are configured?
For output I have optocouplers with connection to 5V and 7i43 is configured as 5V tolerant. But just right now I read that if output is push/pull they leave 1.7V on photocoupler even in logic 1 state, and should be used as open drain. So is it possible to drive all outputs as open drain? (Maybe this is somewhere alreday written but I didn't reach yet). Or new bitfile is needed?
Thanks in advice.
Do you possibly have capitalization wrong?
