Stuck configuring 5i25 to run G540

No-one has any other ideas? I'm at loss here.

if you disconnect the cable, does pin 16 (GPIO16) read high?
The fact that it does not seem to work suggests the the 6I25 might be damaged.

You can verify operation of that pin by reading it in halshow
It should be high if unconnected and low if grounded (jumpered to pin 25)

Is the charge pump on the G540 switched off ?
If you want to use it, i think it will need another stepgen set as a charge pump.
For testing you can switch it off, that should cause the motors to lock when powered and should also move when jogging/working.

I've had a feeling that the card might be damaged, but didn't want to assume that yet.

I was mistaken, it's actually pin 15 that isn't working.

I tested pins 13 through 16 using a jumper with the parallel cable disconnected. 13, 14, and 16 all worked perfectly, but 15 did not change.

I also started a minimal Hal configuration to check the gpio pull up in this is what I got, it seems off.

Hal commands:
loadrt hostmot2
loadrt hm2_pci
loadrt threads name2=test2 period2=1000000
addf hm2_5i25.0.write test2
addf hm2_5i25.0.read test2
loadusr halshow

Here's a screenshot of halshow

Is there a firmware I can flash to the 5i25 to check all the pin's function? Have them all generate a pulse or something like that?

You would have to disable all the stepgens and pwmgens to guarantee that all I/O pins
are left as GPIO:

loadrt hm2_pci config = " num_stepgens=0 num_pwmgens=0"
