Other Parts Discussed in Thread: C2000WARE

Dear all:

目前28002X系列的加密和原先的2806X系列芯片的CSM程序加密差距还是挺大的，到目前还不知道如何设置，

程序中添加了两个 f28002x_dcsm_z1otp.asm f28002x_dcsm_z2otp.asm，文件

但是程序中不知道在什么地方设置密码，

还有CMD文件的设置

}

CMD文件是否就复制这段代码就可以？

这是第一种直接在程序中加密方式，请帮忙指导？

还有使用C2Prog烧入工具加密，也搞不清楚如何设置？

使用C2Prog 设置密码是否key0 key1 key2 key3 key4 都要设置，设置的是格式是什么（0xFFFFFFF）

这是第二种使用C2prog 加密方式，请帮忙指导？

错误提示要求密码改成16位长度: 0xFFFF

1、关于DCSM模块可以看一下这个技术文档的说明：https://e2echina.ti.com/blogs_/b/the_process/posts/dcsm?tisearch=e2e-sitesearch&keymatch=%2522DCSM%2522#

2、关于C2Prog，你可以试一下每个Key中输入0xFFFF。

刚使用C2Prog测试了把8个单元密码都设置为0xfff1,用C2Prog烧写程序后，再通过仿真器进行仿真还是能正常仿真，说明加密无效，

这种方式是否是采用原来的那种CSM加密方式一样，CMD文件应该也要修改。目前280023_Flash_lnk.cmd文件里没有相关的CSM存储单元。

最简单的加密方式还是原先采用CSM方式，现在28002X系列是否还有这种方式？

0 Green Deng 3 年多前回复 Huit Wu

TI__Guru** 101655 points

我这边没测试过C2Prog加密DCSM的，说实话论坛最近几年也没碰到多少人用这种方式加密的。但其实用把加密文件和工程一起烧写进芯片的方式去加密应该也是可以的。

最新的几款芯片都是用的DCSM加密，两者的加密机制有差别，我觉得是不能再使用CSM了

C2Prog写Flash时，尝试使用提供的密码解密Flash，而不是加密Flash

0 Huit Wu 3 年多前回复 Green Deng

Prodigy 200 points

目前正在尝试怎么使用DCSM加密方式，和原来CSM方式比较复杂了很多，你们这边有没实际操作过F280023使用DCSM加密，的经验，

目前我还是有点懵，还没搞明白去配置这些参数，你们能否写一个简单些的操作指南。

一个是上面链接中的FAE分享，一个是你可以对照例程来进行测试学习：

C:\ti\c2000\C2000Ware_4_01_00_00\driverlib\f28002x\examples\dcsm

但都没在C2Prog上测试过。

这个工程我导入看过，在flash模式下，只有syscfg文件里面才有DCSM相关的信息，

正常的28002x_generic_flash_lnk.cmd文件也没DCSM相关的定义，

如果我移植是否只要把dcsm.asm 和dcsm.cmd 文件导入我工程中就可以是否？

0 Green Deng 3 年多前回复 Huit Wu

TI__Guru** 101655 points

.asm可能可以直接导入，但是cmd文件直接导入的话不知道跟你的工程能否兼容。

我之前分享的链接里面有介绍如何修改cmd文件的，你仔细参考一下

0 Huit Wu 3 年多前回复 Green Deng

Prodigy 200 points

我把.asm导入进去是的可以的

但是CMD文件导入进去，编译不通过了

这种错误是什么问题？

0 Green Deng 3 年多前回复 Huit Wu

TI__Guru** 101655 points

你的程序里面现在有两个cmd文件（不包括nonbios那个），所以肯定会报错。把原来的flash的cmd文件exclude from build之后再试试。另外include的路径也要添加好。

0 Huit Wu 3 年多前回复 Green Deng

Prodigy 200 points

使用exclude from build 正常的flash 的CMD文件都屏蔽了，程序都无法正常编译了，能具体告诉我怎么把这个DCSM的CMD文件添加吗？是直接复制到flash的CMD文件里，还是具体怎么操作，毕竟我们只是学会应用就可以，有必要的话我可以把我的工程上传，你们帮我查看操作一下。

0 Green Deng 3 年多前回复 Huit Wu

TI__Guru** 101655 points

直接复制到cmd文件中

上面那个链接里面介绍的很详细了，这是TI官方的FAE自己写的应用经验分享，链接里面除了图片没办法正常显示，其他的都讲的很明确了，认真参考一下：

这个文档我看了几遍了，没有说到，把DCSM的CMD文件怎么和Flash的CMD文件结合，我也试过了把DCSM的CMD文件直接复制到flash中，无法编译通过
