CCS编译placement fails for object ".txet"

Zhiqiang Dong1

我的CCS编译的时候报错：placement fails for object ".txet" , size 0x152d(page0) . Available ranges :PRAMH0 size:0x1000 unused:oxfbd max hole:0xfbd 。

size:0x152d(page0)表示编译生成的汇编指令代码大小0x152d ，Available ranges :PRAMH0 size:0x1000表示存放.text字段的空间大小为0x1000 ，unused:oxfbd表示暂时未被利用的空间为0xfbd ,因为0xfbd < 0x152d所以 placement fails for object ".txet" 。这样理解是否正确？

那么这种情况下如何修改SRAM.CMD的.text字段？

谢谢！

代码过大，可以把其他空间分配给.text段

请问怎么把其他空间分配给.text段，书上没有讲怎么操作SRAM.CMD ，可以举个例子吗？谢谢~

你把你的CMD文件都贴出来，只要|上另外一块内存区域就可以

其中

PRAMH0 : origin = 0x3f8000, length = 0x001000

DRAMH0 : origin = 0x3f9000, length = 0x001000

我将上面的两个字段修改为

PRAMH0 : origin = 0x3f8000, length = 0x002000

DRAMH0 : origin = 0x3fa000, length = 0x001000

就可以啦，但是不知会不会导致其他存储错误

有可能有有问题，具体要看这两个RAM区域是否真的有这么长，你用的是C2000哪个产品

用的是320F2812，谢谢

资料上介绍说0x3f8000~0x3fa000是H0 SRAM ， 0x3fa000~0x3ff000为保留，

所以你只要直接把

DRAMH0 : origin = 0x3fa000, length = 0x001000

去掉就可以，就等于不要把H0RAM分成两块，合起来放.text

我把DRAMH0 : origin = 0x3fa000, length = 0x001000 注释后，

将.bss，.ebss，.const ，.econst ，.sysmem字段地址也修改为PRAMH0
修改前：

   /* Allocate program areas: */
   .reset           : > PRAMH0,      PAGE = 0
   .text            : > PRAMH0,      PAGE = 0
   .cinit           : > PRAMH0,      PAGE = 0

   /* Allocate data areas: */
   .stack           : > RAMM1,       PAGE = 1
   .bss             : > DRAMH0,      PAGE = 1
   .ebss            : > DRAMH0,      PAGE = 1
   .const           : > DRAMH0,      PAGE = 1
   .econst          : > DRAMH0,      PAGE = 1
   .sysmem          : > DRAMH0,      PAGE = 1

修改后：

   /* Allocate program areas: */
   .reset           : > PRAMH0,      PAGE = 0
   .text            : > PRAMH0,      PAGE = 0
   .cinit           : > PRAMH0,      PAGE = 0

   /* Allocate data areas: */
   .stack           : > RAMM1,       PAGE = 1
   .bss             : > PRAMH0,      PAGE = 0
   .ebss            : > PRAMH0,      PAGE = 0
   .const           : > PRAMH0,      PAGE = 0
   .econst          : > PRAMH0,      PAGE = 0
   .sysmem          : > PRAMH0,      PAGE = 0

这样前面的问题就解决了。

但是我使用的double数组变长后，long double x[NCAL+1] = { 0 }; NCAL从10变到100后

报错：placement fails for object ".econst" , 请问这种情况怎么处理？谢谢！

说明你的PRAMH0 RAM也不够了，你需要把他改成RAML0 或者RAML1，发现你的CMD并没有写这一段就在PAGE1里面加：

RAML01 : origin = 0x00 8000, length = 0x002000
