TI中文支持网.test 程序空间太大，无法放在内部RAM中运行，希望把程序放在外部RAM中运行。看了以前的问题回答还是没有实验成功。我修改如下：
1、配置芯片GPIO84~87引脚， 引导模式为Jump to XINTF x16。
2、修改CMD文件如下：
MEMORY

3、程序中使用：init_zone6（）；
还是没有成功，我还需要修改哪里或者在哪里加程序。
CMD文件修改的对吗？
Gavin J：
恐怕你要把程序烧到 flash了。
可以使用在flash运行的cmd文件。

zhongliang lu：
回复 Gavin J:
为什么呢？不能在外部RAM运行吗，还是硬件有问题？外部RAM是好用的，我调试过。
