TI中文支持网Part Number:TMS320F28335Other Parts Discussed in Thread:UNIFLASH
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。

Green Deng：
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。

fusheng lu：
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
