1. ccs工程的頭文件找不到，怎麼回事
1、要在Memory Section Manager屬性中為「Segment For DSP/BIOS Objects」 和 「Segment For malloc()/free()」分配Dynamic Memory Heaps，必須首先在要分配的段（比如，IRAM）中勾選「create a heap in this memory「，並給出heaps size。
2、要把*.tcf文件生成的*.cmd文件手動加入工程中，否則編譯報錯如下：

warning 的原因是對應行的元素沒有聲明。
解決辦法就是加入聲明。
舉例如下：
#include <std.h>
#include <string.h>
//#include <stdio.h> //打開該句就可以了
void main(void)
{
unsigned int i;
unsigned int sum=0;
for(i = 0; i<=100; i++ )
{
sum += i;
}
printf("the sum = %d .\n",sum);
printf("the program run over!\n");
printf("the program run over!\n");
2. CCS3.3編譯提示cmd中提示找不到*.OBJ文件，可是debug裡面明明有obj文件啊
error: system error, can't open file '/.obj' for input: No such file or directory
對應解復決辦法：1要在cmd文件中制的vectors.obj前面添加-x.\Debug\代碼才可以正常運行。
2要進行Project→Build options ---basic---Auto mod ----No auto即可
3. 為什麼我的CCS3.3軟體安裝時出現找不到源文件，忽略這項安裝後寫程序編譯提示出錯
設置路徑 project=>build options => compiler下的preprocesser，有個include search path，就可以設定頭文件了，ok
4. 錯誤:CCS在鏈接時出現lib文件找不到
而是樓書的庫有復問題，「制member 'csl.obj' has incompatible byte ordering」，估計是大端小端的問題，可能是該庫在編譯的時候所選用的便宜參數和你的project環境不同，建議樓主重新編譯該該庫，然後替換原來的。
5. ccs6編譯工程和文件時總出現這個，怎麼辦啊，急
低版本是無法兼容高版本的文件的，只能升級cssv6，下載後，然後在項目右鍵 properties中選到general,選complier version 旁邊的more就可以選你安裝。
利用CCSv5導入之前版本工程（*.pjt）的方法
其實很簡單，使用File-Import
只不過是不要選版擇(General)Existing Projects into Workspace，那裡會提示「Some projects cannot be imported because they already exist in the workspace」，而是要在Import的時候選擇（Code Composer Studio）Legacy CCSv3.3 Projects
進入後直接選擇相應的*.pjt文件
之後沒有特殊要求就權一路Next直到Finish就好啦。導入後Build應該沒問題。
至於Debug的需求，還是需要新建Target Configuration File，按需要選擇模擬器，就可以了。
