hi Green，

     问题已经解决了，在MemCopy程序中用的是大写的Ramfuncs，但是在程序中是是小写的ramfuncs，所以就出问题了。改了就可以进主程序了。

但是用到CLA这部分，拷到RAM里边出现了死循环，一直停在了MemCopy子程序中，我把几个代码贴上来，帮忙看看，谢谢！

1、下边的CLA的拷到ram中，是第1句程序还是第2句？我现在用第一句的时候一直停留在memcopy这个函数中。

2、MemCopy函数是：

3、CLA定义的程序是：

4、CMD文件/* User specific Linker command file for running from FLASH *//*==================================================================================*//* FILE: F28035_FLASH_HVPM_Sensored.CMD *//* *//* Description: Linker command file for User custom sections targetted to run *//* from FLASH. *//* *//* Target: TMS320F28035 *//* *//* Version: 1.00 *//* *//*----------------------------------------------------------------------------------*//* Copyright Texas Instruments 锟� 2009 *//*----------------------------------------------------------------------------------*//* Revision History: *//*----------------------------------------------------------------------------------*//* Date | Description *//*----------------------------------------------------------------------------------*//* 4/13/09 | Release 1.0 New release. *//*----------------------------------------------------------------------------------*/

/* Define the memory block start/length for the F28035 PAGE 0 will be used to organize program sections PAGE 1 will be used to organize data sections

Notes: Memory blocks on F2803x are uniform (ie same physical memory) in both PAGE 0 and PAGE 1. That is the same memory region should not be defined for both PAGE 0 and PAGE 1. Doing so will result in corruption of program and/or data.

L0 memory block is mirrored - that is it can be accessed in high memory or low memory. For simplicity only one instance is used in this linker file.

Contiguous SARAM memory blocks or flash sectors can be be combined if required to create a larger memory block.*/
