TI技术支持：
您好！为了维护28335的密码不被别人发现，我用uniflash工具同时烧写两个out文件，第一个out文件主要是解密，放在RAM空间，第二个out文件是应用程序和加密程序，放在flash空间，真正的烧写文件。
将两个文件同时加载在uniflash窗口，点击load images，显示Error! Overlapping segments at address 0xf000。但是程序里第二个文件我并没有用到这段空间，为什么还存在这种冲突？我把两个CMD文件附在下面，您帮我看看是什么地方的问题？或者是uniflash不支持这么做，但是我在论坛里有网友说只要段不冲突，是可以加载两个out文件的，况且我的两个out文件，一个是在RAM，一个是在Flash。

Uncomment the section below if calling the IQNexp() or IQexp()
functions from the IQMath.lib library in order to utilize the
relevant IQ Math table in Boot ROM (This saves space and Boot ROM
is 1 wait-state). If this section is not uncommented, IQmathTables2
will be loaded into other memory (SARAM, Flash, etc.) and will take
up space, but 0 wait-state is possible.

}抱歉，着实没有试过同时烧写两个out文件的，不知道能否实现。你有参考的论坛哪个帖子方便发过来看看吗？
另外，我的理解，你的其中一个.out文件就是为了解密准备的？这样的话为何不直接使用uniflash上自带的加密解密工具呢？这样不管是开发还是使用都方便很多，效果也是一样的。
uniflash确实可以解密，但是这个密码是显性的，操作的人也能看见。还有一种隐性加密解密，操作的人不知道密码。
下面这个帖子介绍了两种方法max.book118.com/.../103682256.shtm
