OKMX6UL-C2板SD卡启动失败，也无法烧写NAND
OKMX6UL-C2板，256D256N。SD卡：16G class 10
使用近期飞凌嵌入式网盘里OKMX6UL-C2(eMMC&Nand版)->linux->工具->SD->启动->256Mnand下的createSdcard-sdrun.tar.bz2制作SD（启动）卡，在kernel已启动、将要引导文件系统时出错，贴出（部分）启动信息如下：。。。。。。。

似乎是SD硬件问题。
请技术支持帮助判断一下 使用过多块SD卡，只这块16G Class 10还算好，其它4G低速、16G高速的都无法读出zImage或dtb。

class10就已经算是高速卡了，您参考6ul的应用笔记文件夹下的“针对SD_class10卡不识别的问题解决方法”的文档，操作一下，或者您换一个class4的低速SD卡试一下 请问版主：参考6ul的应用笔记文件夹下的“针对SD_class10卡不识别的问题解决方法”的文档，
是在光盘里？还是在论坛里？我没有光盘。我始终没找到。望再明示。 借来一个8G、4C的卡，现在可以了！！
