Optee on startup

hi
i made a trusted application base on op-tee with the name of test_app and it work fine when i test it by sudo test_app in terminal .
i just want to run this application on startup before GUI coming up
i cant make a service to run in startup because it is accessible by third party users and they can modify services and delete it .
i want to do something that nobody couldn’t delete it from boot sequence without system failure .
can you help me about it ?

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.

hello rabanimisagh,

could you please try adding a service within /etc/systemd/system?
