关于F280049C加密问题
1:ASM文件是用SYSCONFIG产生的ASM文件和CMD文件
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.
