3.2 Supporting Files

The additional device_cmd.c, device_cmd.h, device_cmd.opt and device_cmd.cmd.genlibs are supporting files generated by the tool.

The code generation includes a LIVE DIFF tool which showcases how the changes in the GUI cause changed in the generated code.

If you decide that a section must be loaded and run from a different address, then the generated format of the entries in the linker cmd file automatically change.

Once the Place copy table in BINIT section is deactivated, the .c and .h files are also updated and the initialization code needed is automatically generated.

You need to call the CMD_init function in your application code to initialize such sections. The device.c for C2000 devices includes a Device_init function that can call this function, if needed.

device_cmd.opt and device_cmd.cmd.genlibs automatically setup the Code Composer Studio project properties.

The OPT file creates a predefined symbol for CMDTOOL and the active CMD module instance name.

These predefined symbols are used in application C code: device.c and device.h files.

The device_cmd.cmd.genlibs file follows a similar path.
