程序从Flash_to_RAM后无法运行

Other Parts Discussed in Thread: CONTROLSUITE

MCU为F28069,采用Flash_to_RAM的方法，把所有程序都从FLASH移到RAM中运行，但程序运行后无法跳转到main()，不知道什么原因，是因为CMD文件有问题吗？大家帮忙看看。

controlsuite中的工程都可以实现搬移吧。 TI提供了代码只需使能宏定义就可以了你试试那个

拔掉编程器（XDS100V3）后程序运行是正常的，就是接编程器在仿真状态下进入不了MAIN()，也不能正常运行。是设置问题还是仿真器有问题呢？有人知道怎么解决吗？

仿真器只要能实现程序下载就应该能调试 ccs工程属性下的程序入口设置一下看看

我看CCS里设置的是:

Auto run option:

Run to symbol main

还要设置哪里？

连上仿真器不能直接调试。需要重新加载仿真是在ram中跑

ERIC:
你这中做法就不对。哪有把所有的代码都从flash搬移到RAM运行。
如果你想直接在RAM中运行，进行调试，那用RAM的cmd不就可以。
如果你想一部分的代码放到RAM中运行，那么参考initflash的这个函数以及cmd。
你这种CMD把main都弄到RAM里面去了，谁在执行memcpy的函数的工作，难怪会跑不到main.

我也觉得不需要全部进行复制转移吧，你看下仿真设置那边呢

程序写到芯片后，采用断开仿真器，再连接的方式有一定几率复位到main（），要多试几次就可以了。成功后和正常的仿真是一样的，且后续每次复位都可以定位到main（）。
