280049编译的提示.text空间不够

2021-01-22 分类：C2000™ 32位实时 MCU 阅读(141)

Hi，

我在编译的时候出错，提示.text的section空间不够，提示空间需要0x453a，差不多17k空间，我看了280049的规格书中LS RAM总共才16k空间，不知道在我这种情况下，我应该怎么去分配text这个空间？

报错具体如下：

<a href="file:/D:/TI/ccs1011/ccs/tools/compiler/dmed/HTML/10099.html">#10099-D</a> program will not fit into available memory, or the section contains a call site that requires a trampoline that can't be generated for this section. placement with alignment/blocking fails for section ".text" size 0x453a page 0.

规格书的存储空间如下：

Susan Yang：

您可以在.text分配上合并LSRAM和 GSRAM

,

Hi Susan，

GSRAM我大部分分配给了.ebss。

我现在做了一个测试就是把flash_bank0分配给了.text，在运行程序发现无法正常控制EPWM模块。。不知道怎么回事。

Hi Susan，

还有一个问题就是，我尝试给.ebss分配了RAMLS的空间，在编译的时候提示空间需要0X1148，差不多4k，但是实际上我给他分配了16k，为啥还是会提示空间不够呢？

配置代码为：

.ebss : > RAMLS0 | RAMLS1 | RAMLS2 | RAMLS3 | RAMLS4 | RAMLS5 | RAMLS6 | RAMLS7, PAGE = 0

报错描述为：

<a href="file:/D:/TI/ccs1011/ccs/tools/compiler/dmed/HTML/10099.html">#10099-D</a> program will not fit into available memory, or the section contains a call site that requires a trampoline that can't be generated for this section. run placement with alignment/blocking fails for section ".ebss" size 0x1148page 0.

这个是哪里出了问题了？

,

Susan Yang：

若是可以的话，请您私信一下工程吧，我们具体看一下，谢谢

,

xiao kelvin：

你好，我已经私信你了，请查收！

,

xiao kelvin：

Hi Susan，我把.text的段分配到flash，然后再debug的时候，无法正常运行，提示错误为：
Break at address "0x3fbd92" with no debug information available, or outside of program code.

段配置如下：.text: >> FLASH_BANK0_SEC2 | FLASH_BANK0_SEC3 | FLASH_BANK0_SEC5,PAGE = 0, ALIGN(4)

你也一起帮我看了，
thanks！

,

Susan Yang：

查看您的工程可以看到，您之前cmd的分配并没有成功

而后我修改了一些，您可以看一下。编译后，就没有警告了

Hi Susan，
我看你就是把LS0 1 2 3 4 合并在一起了。我按照你的写法改，空间确实分配开了，也可以debug，但是为什么合并就可以，分开就不行呢？
