是否和编译器版本或者mmc bus的频率有关?

有没有哪位知道mmc bus的频率在哪里设置的，我现在发现28的mmc bus频率比38的高一倍.

居然还有人在这打广告。要么你先回答了我的问题在打也可以啊。太不给力了。

这有高手吗？还是说我太低了？

你可以先不管Wi-Fi驱动，先看看是不是能检测到一个mmc设备，如果没有，后面的wi-fi驱动的probe肯定不会执行
看调试信息mmc1 是没有识别到设备的

我今天也在想这个问题，这是部分打印信息:

看这个mmc1命令发送应该是超时，mmc0是正常的。有没有人能帮我分析下.

mmc0上接的是sd卡，打印上面的信息的时候sd卡是没有插的。mmc1上接的是wifi，打印上面信息的时候是接上的。

同时这个信息是说明mmc1有问题呢？还是说明wifi驱动有问题？

mmc1有问题，与wifi驱动无关
