使用c2000 ware中dcsm_security_tool例程，将RAM LSx、Bank0左右扇区分配到Zone1、Bank1所有扇区分配到Zone2，分别设置了2个zone的密码，debug烧录完代码报下面错误。

使用UniFlash读出来的GRABSECT/RAM值，跟生成的.asm中的不一样
全新的dsp，错误发生在Flash programming 0x78020，是Bank0 Zone Select Block，密码在此区域。说明密码还没有写进去。
这个文章已经看过，F28004x的DCSM稍有不同，生成的DCSM asm cmd文件已经和TRM手册比对过，没发现问题
F28004x注意事项：
1、一旦设置了Zone密码，Flash、RAM LSx的访问就通过GRABRAM/GRABSECT去抓取，所以务必将所有Flash和RAM LSx进行划分加密。
2、GRABRAM/GRABSECT的配置是Zone1和Zone2的组合配置，不是单独的，错误配置将导致无妨访问。
3、在（存在Boot pin不确定的状态）硬件上测试，DCSM一直未成功写入，硬件的缺陷会影响DCSM的写入。
4、第一次烧录加密代码不需要任何额外的设置，后续需要在CCS工程属性->Debug->Flash Settings，CSMPSWD密码区域填入相应的密码。
或者使用UniFlash烧录之前，先通过Settings & Utilities CSMPSWD密码区域填入相应的密码。
5、尽量不要设置Boot ROM相关的，只能设置一次。
