I want to start my application just after login at boot-up : root

systemctl --system daemon-reload
systemctl enable autostartup.service
systemctl start autostartup.service

Could you please help me identifying issue?

Thank you

Your agv_test is started but returns a error code. That’s why systemd reports a failure. You have to debug your agv_test.

Hi @alex.tx ,
Executable is working code, once it was almost ready to release/tested, then only I decided to add on boot-up. Booting agv_test log for your ref.

rtc_main() called thread ID: 11

Could you please help me on this? let me know if you need any more details.

Thank you

Your app may work OK when started form CLI but it doesn’t work when you starting it as a service. May be it relay on some environment variables which does not exists when systemd launch it. Or something else. Unfortunately I can’t debug your app.

Hi @alex.tx
I understand what you say. Let me make one test code just having void main(void) and print, return 0. and update you my findings.
and then I can debug more on what are the dependencies my app has.

Thank you

Hi @alex.tx ,
I verified with my test code and noticed as soon as I login and type anything. my executable launches. is that the right behavior?

Thank you

It depends on your test app. Are you trying to interact with default console? Change you test app for just creating a file and check if file is created. Use an absolute path for file location please.

Hi @alex.tx
Thank you for help on this.

You are welcome.
