器件型号：TMS320F280023C 大家好、
以下是客户提出的问题、可能需要您的帮助：
已尝试使用 F28002X 的 DCSM 加密程序、已查看与 DCSM 相关的文件和 F2800X 的 DCSM_SECURITY_TOOL 例程。 但是、仍不清楚如何在28002X_FLASH_lnk.cmd 处为相关 DSCM 添加 CMD 文件。 根据 F2800X DCSM_SECURITY_TOOL 例程向工程添加了 dcsm.asm 程序：

F2800X 的 DCSM_SECURITY_TOOL 例程中的关联 dcsm.cmd 文件如下图所示：
但是、该例程的28002X_general_flash_lnk.cmd 文件中没有 DCSM、这表示 DCSM 应该存储在 dcsm.cmd 文件中。 如何 将 dcsm.cmd 的内容移植到客户的项目工程文件中？
已尝试以下2种方法、但均失败：
A. 将 dcsm.cmd 的内容直接复制到28002X_FLASH_lnk.cmd 文件中、程序编译失败：

B. 将 dcsm.cmd 文件直接添加到工程文件也失败：
您可以帮助检查此案例吗？ 谢谢。
