TMS320F2812程序调试

只看该作者 · 2009-11-5 13:34

大家好。我最近调试了一个程序，可能是存储器出现了以下问题，大家看一下，是什么原因，调试的时候，出现了：
error:can not allocate .text(sz:00001de0 page:0)in PRAMH0(avail:00000ffe)
error:errors in input -/.Debug/lceshi.out not built

就是出现了上面的错误。我很郁闷。恳请大家帮忙啊

.text 分配空间不够了 PRAMH0只有00000ffe这么大小
而.text有00001de0这么大重新分配下

2楼是正解
地址分配有问题

请问，如何的分配呢？我上传我的存储器的内容，你帮一下吧。

cmd文件memory第一行：
PRAMH0 : origin = 0x3f8000, length = 0x001000
红色那部分，要足够大，但不要超过了你的这部分存储器大小

哪么该写成多大呢？

至少超过00001de0这个值

这样修改可以的。可是我不知道是什么意思。你可否给讲一下为什么这样改？

只看该作者 · 2009-11-9 22:38

.text是你的可执行代码段也包含浮点数常量，你的这些代码大小超过了你定义的PRAMH0的长度4k，大小有0x00001de0,也就是7648个字节，存放不下，所以我给你重新定义了一个块，L0和L1合起来一共有8k的空间，
这样你的.text就能放下了。
L0L1这个名字你可以随便定义，只是因为它的MEMORY名字是L0，L1，为了省事我就这么定义了。
你应该好好看看关于CMD的这部分内容。
