Another custom BOB for 7192TH ?

Another custom BOB for 7192TH ? was created by hpeyerl
After my happy success with the 7i96s, I decided to upgrade my MPCNC 3 axis machine.
Ordered a 7i92th which is now waiting for me to pickup at the post office. Thought I'd get a head start and built a couple cable assemblies. Then started trying to configure linuxcnc.
I think I don't understand something. Since I don't have a BOB expansion card and I was just building a 26pin hdr to my drivers (TMC2208's) I figured it should be relatively straight forward. It doesn't appear to be; at least not to me.
This is what I've built:
P1
PIN Function Descr
IO17 GPIO Input XMin
IO18 GPIO Input X1Min
IO19 GPIO Input YMin
IO20 GPIO Input Y1Min
IO21 GPIO Input ZMin
IO22 GPIO Output Chassis Fan
IO23 GPIO Output PS Fan
P2
PIN Function Descr
IO0 STEP0 X Step
IO1 DIR0 X Direction
IO2 EN0 X Enable
IO3 STEP1 X1 Step
IO4 DIR1 ~X1 Direction
IO5 EN1 X1 Enable
IO6 STEP2 Y Step
IO7 DIR2 Y Direction
IO8 EN2 Y Enable
IO9 STEP3 Y1 Step
IO10 DIR3 ~Y1 Direction
IO11 EN3 Y1 Enable
IO12 STEP4 Z Step
IO13 DIR4 Z Direction
IO14 EN4 Z Enable
and I tried selecting G540x2 'firmware' in pncconfig but I don't seem to have favourable options in the P2 tab for configuring my stepgens.
Sorry, thought I had a handle on this from my previous machine.

pin# is the pin number on the BD25/parallel port connector
I/O is the Mesa input/output number used in HAL

Is a firmware file for the pinout you listed (with 5 stepgens on P2)
and just GPIO on P1
pncconf seems to work with this using the discovery option

That "Thank You" button doesn't adequately express my thanks for your continuing help!Is a firmware file for the pinout you listed (with 5 stepgens on P2)

Thanks!

I was confused because pncconf listed:
P1: 017, 1, 5, 020, 9, 6, 024, 7, 8, 1, 033
P2: 000, 0, 0, 003, 4, 1, 007, 2, 3, 0, 016
as the Pin #'s and I didn't (don't?) understand how to translate that into physical pin numbers on the physical connector. Specifically, how is "000" different from "0" and "0" ?

I agree that pncconf could use better column labeling
The 3 digit numbers are GPIO numbers, and the single
digit numbers are module numbers (like stepgen 0,1,2,3
or pwmgen 1)
For your listed setup, pncconf config page setting should
look like this:
Main config page:
P1 page:
P2 page:

Oh! I had almost that! I missed the 'Amplifier Enable's and the "+ Home" parts of the limits.
