手动拆分.text段

2014-03-18 分类：C2000™ 32位实时 MCU 阅读(310)

下面是我使用的.cmd文件，为什么手动拆分.text编译出错，

"D:\\Tms320f28335Project\\DSP2833x\\v131\\DSP2833x_common\\cmd\\28335_RAM_lnk_text.cmd", line 132: error: cannot find file "myfile.obj"

但自动拆分时没有问题，

手动拆分时，是不是.text1与.text2要像汇编一样在头部添加，如下.sect "codestart"，C语言编程的需要添加吗？

.sect "codestart"

code_start:
.if WD_DISABLE == 1
LB wd_disable ;Branch to watchdog disable code
.else
LB _c_int00 ;Branch to start of boot.asm in RTS library
.endif

Chen Jones：

楼主的myfile.obj文件，在哪里放的？

好像必须要放置在和.out文件在相同路径下，楼主再试试？

谢谢你的回答。

我看了下，是在同一个文件夹，至少生成的.map文件与myfile.obj在同一个文件夹下，因为有错.out生成不了，不拆分的话，一切正常，.out与.obj是在一个文件夹里

谢谢你的回答，确实将.pjt与.obj放在一个文件夹下编译就没问题了。
