在这个中断检测里面打出信息来看下,跟踪一下就好了。
是不是很有什么宏没有开。

一般都应该做好的,
程序如果没有问题,
就是你的sd卡座没有焊接好,
虚焊导致的,
你先看看是不是虚焊吧,

楼主 这个问题,应该好好看下 你的SD在位检测 和拔掉 对应的处理函数;
不仅需要在BOOT启动时,对SD在位进行检测,而且还需在OS跑起后,开一个线程或中断,实现SD在位检测;
另外同样需要拔掉 对应的处理函数,当SD拔掉后,删掉其在DDR或SDRAM中的内容。

买的开发板,用了这么久,应该不会存在虚焊的现象吧。

谢谢,我先看看。我用的是winc6.0的系统,这个和5.0有多大区别?

弱弱的问一句,是不是6410开发板的sd卡两个通道中,一般只能实现其中一个通道热插拔,其他一个通道不行啊?这个通道做其他用途?谢谢!
