关于F280049C加密问题
1:ASM文件是用SYSCONFIG产生的ASM文件和CMD文件
- ASM文件内容:
文件说明内容只是修改了红色部分
密码1,3,4修改为12345678
其它内容一字不改

/* this linker command file is to be included if user wants to use the DCSM feature on the device
* DCSM means Dual Zone Code Security Module.
* This linker command file works as an addendum ot the already existing Flash/RAM linker command file
* that the project has.
* The sections in the *_ZoneSelectBlock.asm source file is linked as per the commands given in the file
* NOTE – please note fill=0xFFFF, this helps if users include this file in the project by mistake and
* doesn't provide the needed proper *_ZoneSelectBlock.asm sources .
* Please refer to the Blinky DCSM example in the controlsuite examples for proper usage of this.
*
* Once users are confident that they want to program the passwords in OTP, the DSECT section type can be removed.

1.4 下载程序到FLASH后,程序不运行了.
1.5 想再次下载程序,芯片锁死了
对应的CCS设置为下图
下载程序图
1.5 用UNIFLASH软件

Green Deng：
程序不运行跟芯片是否加密没有直接关系，你的程序如果在没有加密的状态下能成功下载到flash并运行，那么加密后表现应该一样。
芯片锁死后有进行解密处理吗？否则是无法再次下载程序的
