Hello,
I'm a newbie here in all manner. Neither macineing nor Linuxcnc /Cad-Cam is my desk, however I'm in a big hurry to get it on with. Read a lot, achieved a lot but still far from good.

I've got a machine with XYZ step/dir driven servos and a stepper 4th axis through TB6600.
Have a 7i92 IO card to connect with generic BOBs.
It seems, that succesfully generated bitfiles for BOBs, and managed to set up a working XYZ ini/hal config.

When I was up to add the 4th axis extending the ini/hal statements, got an error message:
"./7i92.hal:227: Pin 'hm2_7i92.0.stepgen.03.enable' does not exist"

When I query the I/O card hmid, it says:
Code:
Configuration pin-out: IO Connections for P2 Pin# I/O Pri. func Sec. func Chan Pin func Pin Dir 1 0 IOPort PWM 0 PWM (Out) 14 1 IOPort None 2 2 IOPort StepGen 0 Step/Table1 (Out) 15 3 IOPort None 3 4 IOPort StepGen 0 Dir/Table2 (Out) 16 5 IOPort StepGen 4 Step/Table1 (Out) 4 6 IOPort StepGen 1 Step/Table1 (Out) 17 7 IOPort StepGen 4 Dir/Table2 (Out) 5 8 IOPort StepGen 1 Dir/Table2 (Out) 6 9 IOPort StepGen 2 Step/Table1 (Out) 7 10 IOPort StepGen 2 Dir/Table2 (Out) 8 11 IOPort StepGen 3 Step/Table1 (Out) 9 12 IOPort StepGen 3 Dir/Table2 (Out) 10 13 IOPort None 11 14 IOPort None 12 15 IOPort None 13 16 IOPort None IO Connections for P1 Pin# I/O Pri. func Sec. func Chan Pin func Pin Dir 1 17 IOPort None 14 18 IOPort None 2 19 IOPort ...

But when linuxcnc statrs, it says:
Code:
Configuration pin-out: IO Connections for P2 Pin# I/O Pri. func Sec. func Chan Pin func Pin Dir 1 0 IOPort PWM 0 PWM (Out) 14 1 IOPort None 2 2 IOPort StepGen 0 Step/Table1 (Out) 15 3 IOPort None 3 4 IOPort StepGen 0 Dir/Table2 (Out) 16 5 IOPort StepGen 4 Step/Table1 (Out) 4 6 IOPort StepGen 1 Step/Table1 (Out) 17 7 IOPort StepGen 4 Dir/Table2 (Out) 5 8 IOPort StepGen 1 Dir/Table2 (Out) 6 9 IOPort StepGen 2 Step/Table1 (Out) 7 10 IOPort StepGen 2 Dir/Table2 (Out) 8 11 IOPort StepGen 3 Step/Table1 (Out) 9 12 IOPort StepGen 3 Dir/Table2 (Out) 10 13 IOPort None 11 14 IOPort None 12 15 IOPort None 13 16 IOPort None IO Connections for P1 Pin# I/O Pri. func Sec. func Chan Pin func Pin Dir 1 17 IOPort None 14 18 IOPort None 2 19 IOPort ...

Own bitfile is flashed directly, not as fallback.

Why the two pin listing doesn't match? Is it a fault, leads to the error in the message? How to get it ower with?

It isn't normally necessary to generate bitfiles, no wonder you are finding this a learnng experience :-)
Most people use pre-defined bitfiles from the hostmot2-firmware package.

"./7i92.hal:227: Pin 'hm2_7i92.0.stepgen.03.enable' does not exist"


Does the "loadrt hm2_eth" line in the HAL file have "num_stepgens=3" ? That will disable your higher-numbered stepgens.
