7i76 not seen by linuxcnc

if in doubt... remove the jumper on W2 on the 7i76 all together and power it up as this then does not set the status to pins 22 to 25 at all otherwise one way grounds them and the other tries to send 5v down / or expects 5v back from them.

pins 22 to 25 will just float.

I suspect that the short circuit protection circuit is kicking in on the 7i76 and is preventing the FPGA on the 7i76 from running.... because jumpers w2 and w1 are down on the 5i25..... which is basically linking pins 22-25 to ground...... causing a short circuit.

it's just a guess though

Upload hal and ini files, maybe the sserials are not loaded there.
What does the loadrt line with 5i25 in it say?

Thanks Robert. Attached are photos of my two boards - I think all jumpers are correct.

 

 

Thanks Tommy. I've attached the .hal and .ini files, as well as the output when I try to run linuxcnc. If I comment out line 29, which links hm2_5i25.0.7i76.0.0.input-04, then linuxcnc loads perfectly and I can jog the axes.
