TI中文支持网目前.out程序有两个，一个是DDR初始化程序，一个是应用程序。仿真调试的时候先加载DDR程序初始化DDR内存，然后加载应用程序，执行的时候会打印一长串地址的错误。如果加载完DDR程序之后，系统复位一下，没有这个问题。这个现象是正常的还是不正常的，还请大神们指点下？

Nancy Wang：
我这边在开发板上试是不需要重新复位的。
你是自己的板子还是开发板？如果是开发板可以试一下GEL文件初始化DDR，如果是自己的板子参考这个链接看一下。
www.ti.com/…/sprabl2e.pdf
或者做一下memory test测试一下DDR的可靠性。

这个问题是因为ddr可靠性导致的吗？

用GEL文件初始化之后还需要执行复位操作吗？

回复 Nancy Wang:
不需要，但是gel文件中“GEL_AdvancedReset("System Reset");”这个语句是不是相当于执行了一下复位操作？

回复 jun li:
是的，参考这个链接看看。
