| Item | Description |
|---|---|
| Tool Name and Command | Path and executable name of the linker, as well as command line options used. |
| Archive Members | The name of any members from archive files that are included in the link. |
| Memory Usage Report | The starting address and length of all output sections in program memory, data memory and dynamic memory. |
| External Symbol Tables | All external symbols in data and program memory. |
| Memory Configuration | All of the memory regions defined for the link. |
| Linker Script and Memory Map | Modules, sections and symbols that are included in the link as specified in the linker script. |
Map File
The following is an example of a linker map file for the MPLAB Discover project “Sensorless FOC using PLL Estimator for PMSM.” Note that sections have been shortened to save space. The character “:” represents lines removed.
