你好:
请问是否有dsp6713在外部SDRAM运行程序的demo或者文档资料呢?

可以在应用程序中用#pragma DATA_SECTION ( symbol , " section name " );和#pragma CODE_SECTION (symbol , " section name " )伪指令可以把数据段或者代码段分配到外部SDRAM。
具体请看下面的编译器手册。
7.9.4 The CODE_SECTION Pragma
7.9.7 The DATA_SECTION Pragma
https://www.ti.com/lit/ug/sprui04b/sprui04b.pdf
下面是个例子供参考。
test.c文件中
#pragma DATA_SECTION(bufferB, ”my_sect”)
char bufferB[512];
在CMD文件中
MEMORY
{
PAGE 0:
DARAM2 : origin = 0008000h, length = 0028000h
}
SECTIONS
{
my_sect: {}> DARAM2 PAGE 0
}
