Functions do not execute, rtapi_print_msg do not print anything was created by GingerPotato

Hi all!
I am working on driver. Inside .hal I add functions like:

loadrt my-driver
addf my-driver.func servo-thread

In code I export it with:

rtapi_snprintf(name, HAL_NAME_LEN, "%s.func", NAME);
hal_export_funct(name, my_function, NULL, 0, 0, comp_id)

Unfortunately function my_function do not execute.
Looking further I start thinking that nothing in my driver doesn't execute: none of rtapi_print_msg prints in terminal, parameters (pins) changed in code (inside rtapi_app_main) are not changed in linuxcnc.
On the other hand, changing function name without its changing in .hal cause error, so some part of code is being executed.
What can I do?

I could send whole driver and configuration packed if someone would be able to look at it

Sounds like you are not using halcompile. It will make your life so much easier and there will be no need for the export_func

If you are using RTAI then your rtapi_print will probably end up in dmesg, not at the terminal.
