Input section symbols are generated by the linker for every input section present in the image.
The following table shows the input section symbols:
Table
C5-5 Section-related symbols
Symbol
Section type
Description
SectionName$$Base
Input
Address of the start of the consolidated section called
SectionName.
SectionName$$Length
Input
Length of the consolidated section called
SectionName (in bytes).
SectionName$$Limit
Input
Address of the byte beyond the end of the consolidated section
called SectionName.
If your code refers to the input-section symbols, it is assumed that you expect all the
input sections in the image with the same name to be placed contiguously in the image memory
map.
If your scatter file places input sections non-contiguously, the linker issues an error.
This is because the use of the base and limit symbols over non-contiguous memory is
ambiguous.
