5i25 board confusion with pins directions

It's an input.

But the HAL pin is an OUT HAL pin, because it supplies a value to HAL.

Yes Andy, but i see the electrical side of this. and the pin goes output when the linuxcnc running, I put the scope in the pin,
and read 5V when linuxcnc running tis goes low 0V, and the 5i25 have the pull-ups enabled, also try to put external pull-ups
and the logical state is in 0V.

why? if declared fine in the hal, the pin goes low?

thanks

Quick test.
With LinuxCNC running open a terminal.

halcmd show param hm2_5i25.0.gpio.nn.is-output

Maybe even try

halcmd setp hm2_5i25.0.gpio.nn.is-output 0

Can you post this information:

1. the result of:

sudo mesaflash --device 5i25 --readhmid > pinout.txt

(post the pinout.txt file here)

2. your current hal file

3. What pin are you are referring to? (Note that header, DB25 and GPIO numbers are all different)

Good morning folks!

I attach the requested files.
with respect :

"3. What pin are you are referring to? (Note that header, DB25 and GPIO numbers are all different)"
is pin 1 of db25 (P3). or gpio.017 (is true?)

thanks for the help

No, as I said before, GPIO17 is on P2 (pin 1) not P3

Hello Folks!.

Well today i solve the problem, due we recheck all and not found errors in wires (sorry Peter by the confusion of P2 and P3, as you say
is as we connect, the "machine" was hooked to 5i25 P3 and working fine the mpg is hooked to P2), we install the linux again, and the linuxcnc and now working fine, the "machine" and the mpg. I don't understand where is the error. for now, is working.

Thanks, Andy & Peter by the support!

now I try to command the speed of spindle with the linuxcnc.
