You can check the config by looking at the dmesg list or running
sudo mesaflash --device 5i24 --readhmid
I didnt have any trouble setting the enables on all 6 of the 3pwmgens in
svsttp6_6, I needed to have the fault-inverts set for all 6 pwmgens.
Ok, I feel that you do not really understand, what I am trying to explain,
so I made 2 videos. In first one the boards are attached to 7i43 card, I am
pressing F2 to enable/disable pwmgens and all the LEDs on both 7i39s
flicker as they should. In the second video I am trying to do the same with
both 7i39s attached to 5i24. I put on HalShow to display status of enable
and fault pins of all 4 instances of pwmgens - they all match, so
theoretically both cards should flicker LEDs, but in reality only one of
them does.
What you said before is that you could not set the PWM enables low and
suggested that there was a problem with the configuration. I verified that the
same configuration was able to conttrol the enables in my test system.
If you are unable to set any pin low on the 5I24s P3, this suggests that there
is something wrong with the jumpering (missing jumper?) for the connector
power or 5V tolerance mode. These jumpers are W5 and W3 respectively.

So I still feel that there is some kind of a problem with this particular
5i24 card. Is there a chance for the jumper settings to affect this?
In the meantime I am trying to set the machine up with 7i43 card to get it
operational and I am using svsttp4_4_7i39.bit firmware. There are _no_
stepgens enabled, so all 8 "sense" lines should be available as GPIO (I
need 4 inputs for homing switches). I verified on the backside of 7i39 card
with multimeter that voltage changes from 0,07V to 3,33V in the cable going
to 7i43 as I trip/untrip those switches, but HalShow does not detect a
change of gpio input pin state. I watched all of them at once, so there was
no way that the one pin I was watching was not the right one.
I just checked - HalShow detects switch trips, when 7i39s are attached to
5i24. Could it be that there is jumper that selects between 5V and 3,3V
inputs on 7i43? I do not see anything like that in manual.
This is on page 7 of the manual
Are you sure you have the correct GPIO pins? P4 (the inboard connector) is
GPIO 0..23 and P3 is GPIO 24..47
