2812往Flash里固化时添加哪个库，可以更改么-TI中文支持网

我的程序在ram调试的时候用的是rts2800_ml.lib库，而想要往Flash里固化则必须改成rts2800n.lib这个库，可更改成这个库后在线调试条用的一些字符串函数就不能用了，请问想Flash里固化的库是固定的么和什么有关系怎么更改

Hank Zhao：

使用rts2800_ml.lib也可以往flash里烧写程序，您在使用rts2800_ml.lib烧写程序到flash时出现的是什么问题？

回复 Hank Zhao:

显示烧写成功但是重新上电后并不运行步骤和使用rts2800n.lib的一样，但是只有使用rts2800n.lib上电后能运行

把你的FFTFLASH.cmd文件发过来看一下吧

您好，请将源文件“DSP281x_CodeStartBranch.asm”添加到工程中，并且在CMD文件的section部分添加语句“codestart : > BEGIN PAGE = 0”。

具体是什么情况？编译工程的时候有没有把“DSP281x_CSMPasswords.asm”添加到工程中去，在操作flash programmer有没有改变密码区的值？除了这两种情况，在烧写的时候电源不稳定也会导致flash被锁。
