Problems with PREMPT_RT kernel error and 7i76e

The calibrate screen won't allow me to test the tune of any axis and it won't allow me to save any changes to the INI file.

Are you saying it does not show step timings?
or that you can not edit the fields?
or that the test button does not update the hardware?
or that the refresh button does not show the updated values?

The calibration screen shows three tabs for axis0, axis1, and axis2.

I can edit the fields in axis0, and axis2, but the page for axis1 is esentially blank with only the headings and row of buttons (PIDs etc. do not display).

If I try to save to file in any tab, it gives me an error. If I try to test any axis, it give me an error.

That's probably a INI file error of some kind
Calibrate relies on parsing the INI file to fill out the calibrate menus
and any mistakes or missing items in the [AXIS_N] sections of the
INI file will cause problems

So, is there a way to correct the error I get when using PNCconf. Could this error also be related to incorrect entries in the INI file?

Is this error because PNCconf is not set-up to use PREMT-RT?

I doubt the INI errors have any relation to preempt-RT at all

I would just look at the INI file and see whats wrong with AXIS_1

Calibrate works for me with this set of hal/ini files

Maybe they can give you some hint of whats wrong with your config files

Did you resolve this problem?
I get the same error with PnCConf, 7i76e and PREMT_RT:

roger@linuxcnc:~/linuxcnc/configs/millton$ uname -a
Linux linuxcnc 3.2.0-4-rt-amd64 #1 SMP PREEMPT RT Debian 3.2.81-1 x86_64 GNU/Linux

Error message:

"PNCconf encountered an error. The following information may be useful in troubleshooting:

elif hal.is_rt and not hal.kernel_version == actual_kernel:

I suppose there is an attribute called kernel_version that is missing int the ini file.
Any idea to solve this?
