CCS中,#pragma CODE_SECTION(boot,".bootload")语句不起作用

所用版本为CCS3.3.83；程序编译通过，但是load后（未运行）发现该语句没有起到任何效果。

CMD文件已经修改。

在做bootloader时用C语言（非汇编）直接写的程序，拿来用，结果发现#pragma CODE_SECTION(boot,".bootload")语句不起作用，未能够达到预期的分配效果。

所用版本为CCS3.3.83，程序编译能够通过，但是load后（未运行）发现该语句没有起到任何效果，boot()函数未被分配到boot函数代码段空间。

请各位专业人士指教问题原因
另：使用CCS3.3.38编译正常，代码段分配正常

Shine：

你到.map文件里看一下.bootload段有没有分配到指定的段？

回复 Shine:

.map文件中，boot_ram段占用量为零

能把相关的code_section代码和cmd文件贴出来么？

在另一台上装了一下，编译后map文件和boot文件如下

 

以下为boot部分

#define AWCCR*(unsigned int *)0xf0000004

以下为编译后map文件
