28069加密后，C2000-GANG可以读出Falsh文件，加密不起作用？？？？怎么解决？

2017-08-15 分类：C2000™ 32位实时 MCU 阅读(440)

使用F2806x_CSMPasswords.asm文件添加到工程中，设置好密码，编译可以通过，生成的HEX文件使用C2000_GANG烧写成功，但是使用C2000_GANG界面中的读数据，可以把烧写进去的HEX文件给读出来，加密不起作用？？？？是不在主程序中还要进行相关配置，还是CMD文件不对？

F2806x_CSMPasswords.asm中的代码如下：

.sect "csmpasswds"

.int 0x1111 ;PWL0 (LSW of 128-bit password)
.int 0x2222 ;PWL1
.int 0x3333 ;PWL2
.int 0x4444 ;PWL3
.int 0x5555 ;PWL4
.int 0x6666 ;PWL5
.int 0x7777 ;PWL6
.int 0x8888 ;PWL7 (MSW of 128-bit password)

.sect "csm_rsvd"
.loop (3F7FF5h – 3F7F80h + 1)
.int 0x0000
.endloop

我按照你的方法试验了，发现用仿真器debug模式下烧写程序是加密成功，并且再次用仿真器debug模式，芯片已经被锁住了，如下图：

这个用debug模式烧写锁住的芯片使用C2000-GANG也是已经没办法烧写和读出程序，

但是我使用工程编译出的Hex文件，使用C2000-GANG烧写，芯片还是可以正常烧写和读出，说明

工程编译出来的Hex文件是没有被加密的，编译出来的.out文件在debug模式下烧写是加密的，

现在问题是如何设置hex文件也被加密，因为产品量产使用的C2000-GANG来烧写，并且只认识hex文件

你是用仿真器加密的吗？

使用F2806x_CSMPasswords.asm文件添加到工程中，设置好密码，编译可以通过，生成的HEX文件使用C2000_GANG烧写成功，但是使用C2000_GANG界面中的读数据，可以把烧写进去的HEX文件给读出来，加密不起作用？？？？是不在主程序中还要进行相关配置，还是CMD文件不对？
