Auto startup for SC20 Yocto Linux

Hello everyone, I would like to run an execule file after the module finishs powering up. Is there auto startup service guide for SC20 or I’m missing something. It would be kind if someone help me figure this out. Best regard.

Quectel SC20 Yocto support init and systemd both.

And it is recommended to add service by systemd.

Thank you so much for the reply. I’m looking forward to this method
