TMS320F28377D: 28377D GSRAM分配问题

Xiaofeng NIU 说：

但是如果将GSRAM4及以上任一内存分配给.stack区域，则程序会跑飞

请问有什么编译报错呢？若是可以，能否给出cmd文件？

PAGE 1 is used for data sections. For example .stack.

另外请您参考

编译没有报错，但是debug时程序会跑飞   涉及stack的cmd 配置如下：

若是可以的话，请上传一下工程，谢谢

工程不太方便上传，涉及公司内部信息。以上cmd文件，如果我将.stack的内存这里配置为RAMGS0/1/2/3或者LSRAM任何一个都可以正常运行，但是如果配为RAMGS4以上任意内存，程序都会跑飞。

另外您给的链接我看到关于.stack这里有个说明：Volatile memory (SRAM). The C28x Stack Pointer (SP) is 16 bits. .stack must be in the low 64k words.请问 low 64k words是什么意思，没有理解？

关于堆栈的限制，.stack 部分必须链接到数据存储器的低 64K
