But I have tried both adding gpio to user and not adding. (They were with fresh image install)
I hav read all that link before writing here but nothing changed.
I am using hal and ini files from another working rpi5. Their user names, file names and locations are same.
If i added hal_gpio to hal file, it gives an error about permission.
I added gpio to user, not worked.
I have created 90-gpio-access file as it described, not worked....
The only thing that I havent tried is SPI... I will try it and write here...

I try man hm2_modbus
and man mesambccc
not exist in my linuxcnc i have the last version 2.9.4 i see in linuxcnc official site this is the last version, if there is newest version tell me please
 

Hi all,I’m running into an issue with my 7i77 analog outputs and could really use some help figuring it out.Setup:

• 7i94 + 7i77 + 7i84
• LinuxCNC with Mesa HAL configuration
• QtDragon GUI

The issue:

• When I set hm2_7i94.0.7i77.0.1.analogena to True, I measure about 0.3V on all +-10V outputs, even without setting any value on an analogout<>.
• When I set a value on one of the analogout<> pins (e.g. analogout2 = 0.1) and leave analogena False, I measure no voltage on the corresponding output.
• What I expected:
  • No voltage at the +-10V outputs just by enabling analogena.
  • A voltage at the specific output only when both analogena is enabled and an analogout<> value is set.

My question:

Is this normal behaviour, or am I missing something in the configuration or wiring? What should I check next to diagnose this?
