Re: about the difference of device tree use method compare with linux?



Your comment is correct - there is such a difference.
It is not dynamic because of performance reasons. All drivers would simply be bigger - thing not welcome in uC world.

Personally I am not convinced DTS should be used in Zephyr due to this limitation. Since it is not a separate system component you cannot embed HW configuration that would stay on the board regardless of the FW. Anyway somebody thought it would be nice to separate things related to HW into DTS. I think however that this splits configuration into two (HW vs FW) without any good use case.

If you want to keep configuration in runtime you should use settings. Otherwise you can create your own dedicated partition and store things there in any way you prefer.
