C.2 Linker-Generated Copy Tables and CRC Tables

In this example, three tasks exist in separate load areas. As each is needed, it is copied into the common run area and executed. A separate copy table is generated for each task (see table() operator in ex1.cmd). CRC values for the task functions are verified as well. See Example 7 for the crc_table() operator calls.

To run a simple example that uses copy tables and CRC tables, follow these steps:

1. Create a CCS project with an empty main.c file.
2. Create following files in the project and copy code into the files from the following examples:
   • main.c (Example 2)
   • crc_tbl.h (Example 29)
   • check_crc.c (Example 3)
   • ref_crc.c (Example 1)
   • task1.c (Example 4)
   • task2.c (Example 5)
   • task3.c (Example 6)
3. Edit the linker command file (*.cmd) provided for your target in the CCS project. Add the UNION statement in Example 7 to the SECTION directives in the file.
4. Build and test the project. You should see the result: "Copy table and CRC tasks PASSED".
