A.3.2 Linker Command File for TMS320F206 Sample Assembly Code
/********************************************************************************/
/* Filename: ASMEXAMP.CMD */
/* Description: Linker command file for ’F206 example of on–chip */
/* flash programming from assembly. This command file links the example to addr */
/* 0x8000 of the on–chip SARAM so that the debugger can be used to set */
/* breakpoints. Another benefit of linking the example to SARAM is that the */
/* code can be modified to operate on either flash module0, or module1, or */
/* both. */
/* Notes: */
/* 1. This example expects the ’F206 SARAM to be mapped in both data space */
/* and program space (DON=PON=1). */
/* 2. The object modules for the standard flash algos are expected to be in */
/* a subdirectory (ALGOS) of the path of this file. */
