Root regions

A root region is an execution region with an execution address that is the same as its load address. Each scatter-loading description file must have at least one root region.

One restriction placed on scatter-loading is that the code and data responsible for creating execution regions cannot itself be copied to another location. As a result, the following sections must be included in a root region:

Because these sections are defined as read-only, they are grouped by the * (+RO) wildcard syntax. As a result, if * (+RO) is specified in a non-root region, these sections must be explicitly declared in a root region using InRoot$$Sections.
