各位大神好，28377D的DCSM从头到尾也看了两遍了，DCSM的寄存器也看了，然后就修改了以下的加密代码，使用的是controlSUITE里的blinky_with_dcsm_cpu01，相关内容如下：
1、项目文件
2、2837xD_dcsm_lnk_cpu1.cmd 内容

6、在烧写进去的时候，报警
C28xx_CPU1: GEL Output: Memory Map Initialization Complete C28xx_CPU1: If erase/program (E/P) operation is being done on one core, the other core should not execute from shared-RAM (SR) as they are used for the E/P code. Also, CPU1 will be halted to determine SR ownership for the CPU which will run the Flash Plugin code, after which CPU1 will be set to run its application. User code execution from SR could commence after both flash banks are programmed. C28xx_CPU1: Error during Flash programming (Flash algorithm returned error code). Operation cancelled. C28xx_CPU1: File Loader: Memory write failed: Unknown error C28xx_CPU1: GEL: File: E:\Software\NEEFLCT100100A-B01\DCDC-DCSM\v210\F2837xD_examples_Cpu1\blinky_with_DCSM\cpu01\ccs\CPU1_FLASH\blinky_with_dcsm_cpu01.out: Load failed.
请问下哪里出了问题呢？ 谢谢了。
