error on a modified component

Hello everyone and happy new year
I modified the pwmgen.c component to be able to easily control an rc servo...
like pwmgen it has 3 possible configurations and I can load multiple configurations at the same time
despite the countless compilation errors I managed to create a valid compilation... after which the errors that linuxcnc gave me at startup arrived... using the terminal and halrun I reset all the messages it gave me and from the terminal the component runs with all configurations
when I try to start it from linuxcnc it only works with configuration 1 and gives me the error of the attached report

why does he do this?
how can I fix it?
ps.
then I have to see if it works on a logical level... but that's another story

ciao

It might be a little easier for debugging to just load the component
with halcmd -kf  rather then running a full LinuxCNC installation

halcmd -fk
halcmd: loadrt pwmgen output_type=0
halcmd: addf pwmgen.update servo-thread
halcmd: addf pwmgen.make-pulses base-thread


Note: You seem to be using a Mesa card so using the hardware
RCPWMGEN is a possibility.

 

i've do your command

bobwolf@fresacnc:~$ halcmd -fk
halcmd: loadrt rc_gen output_type=0
Note: Using POSIX realtime
halcmd: addf rc_gen.update servo-thread
HAL: ERROR: thread 'servo-thread' not found
<stdin>:2: addf failed
halcmd: addf rc_gen.make-pulses base-thread
HAL: ERROR: thread 'base-thread' not found
<stdin>:3: addf failed
halcmd:

and this if i put in the .hal file
loadrt -fk rc_gen output_type=2

Debug file information:
./custom.hal:20: waitpid failed /usr/bin/rtapi_app -fk
./custom.hal:20: /usr/bin/rtapi_app exited without becoming ready
./custom.hal:20: insmod for -fk failed, returned -1

I tried to comment (exclude), in the .hal file the lines of my component and if I exclude the line
addf rc_gen.update servo-thread
linuxcnc starts normally
Is there maybe some problem with that part of my program?

Could you post the contents of your component?

here is my file...
I'm not a programmer and I'm self-taught
the file is a modification of the pwmgen.c file

 Sorry my example assumed LinuxCNC was running

A stand alone example would be:

halcmd -fk
halcmd: loadrt pwmgen output_type=0
halcmd: loadrt threads
halcmd: start
halcmd: addf pwmgen.update thread1
halcmd: addf pwmgen.make-pulses thread1

Have you considered using the hardware RCPWM?
It would have much better resolution than a software PWMgen
especially since the full scale RC PWM range is only 1 ms


 

if I start linuxcnc my program with configuration 1 everything is fine and it doesn't give me errors
if I set 0 or 2 in my program linuxcnc doesn't start

below is the terminal if I follow the steps you told me:

halcmd: loadrt rc_gen output_type=0
Note: Using POSIX realtime
halcmd: loadrt threads
halcmd: start
halcmd: addf rc_gen.update thread1
halcmd: rtapi_app: caught signal 11 - dumping core

halcmd: addf rc_gen make-pulses thread1
HAL: ERROR: bad position: 0
<stdin>:12: addf failed
halcmd: unloadrt rc_gen

ok i haven't understand...
i've open halcmd -fk on terminal
i've run linuxcnc from the desktop icon
halcmd exit from terminal with no message

bobwolf@fresacnc:~$ halcmd -fk
halcmd: bobwolf@fresacnc:~$
