Hi again Sahil

For question one. I would reefer to the Zephyr documentation you can read here

For question two: The sys_init() macor is used when you need to run a function at boot stage. The macro does not take any config or runtime data structures and there isn’t a way to later get a device pointer by name. The same device policies for initialization level and priority apply. The Zephyr documentation explains it here

Hi runsiv

Thanks for the reply. I read the posts you shared and I have some questions.

1. In the post it is said that peripherals are initialised before application main is executed. Can you explain how that is done? also, could you give me some example how those peripherals are getting initialised?

2. Also, can you explain me what exactly SYS_INIT does in details?

Regards,

Sahil
