help
If the linker finds orphan sections, it attempts to place orphan sections after sections of the same
attribute such as code vs data, loadable vs non-loadable, etc.
That means that orphan sections could placed between sections defined in IDF linker scripts.
This could lead to corruption of the binary image. Configure the linker action here.

Places orphan sections without a warning message.
