8.8.1 Using Copy Tables for Boot Loading

In some embedded applications, there is a need to copy or download code and/or data from one location to another at boot time before the application actually begins its main execution thread. For example, an application may have its code and/or data in FLASH memory and need to copy it into on-chip memory before the application begins execution.

One way to develop such an application is to create a copy table in assembly code that contains three elements for each block of code or data that needs to be moved from FLASH to on-chip memory at boot time:

The load address
The run address
The size

The process you follow to develop such an application might look like this:

Build the application to produce a .map file that contains the load and run addresses of each section that has a separate load and run placement.
Edit the copy table (used by the boot loader) to correct the load and run addresses as well as the size of each block of code or data that needs to be moved at boot time.
Build the application again, incorporating the updated copy table.
Run the application.

This process puts a heavy burden on you to maintain the copy table (by hand, no less). Each time a piece of code or data is added or removed from the application, you must repeat the process in order to keep the contents of the copy table up to date.
