CMD文件报错，请问能不能改变MEMERY{ }里面的内存段的大小啊 。比如说我想将SHRAM o = 0x80000000 l = 0x00020000这个128k的内存段改大一点。有没有人遇到过类似的问题，怎么解决的。
Tony Tang：
cmd的memory要根据板子及芯片的实际内存大小编写。
Shareram对于芯片来说是固定的，不能改。你可以把这段section分配到DDR上去。
Shine：
请问用的是哪款芯片？ cmd文件的memory要根据芯片数据手册memory map表写。

"修改一些相关的起始地址和内存大小，最后好了，很高兴。" 网上说可以修改起始地址和内存的大小是什么意思。另外我把.far那段放到DDR2里面去，还是会报错，但是没有其他的错了啊。之前的那行关于.far内存分配报错没了。

上面的错误是说这些函数没有找到。
但是说不通啊。前面的错误是在link阶段，应该编译都通过了。怎么改cmd会有这个错误呢？程序也改了？

回复 Tony Tang:
程序没有改，只是按你您说的把.far这个section从SHRAM改到了DDR2中，只有这一个改动，截图中有体现

这是工程中原始的CMD文件中报的错

将SHRAM改为DDR2后.far上面的×没了（编译通过了？），报了后来的错

解决了，就是要在linker里面包含lib文件。非常感谢
sfloat s：
主要看你的硬件实现的存储器空间大小，CMD得与实际的存储器对应
如果有更大的空间，可以改大。如果没有空间即使改大了，编译通过也跑不起来。
