关于Beaglebone Black裸机从sd卡启动的问题

user4863670

您好，

我刚购买了一块Beaglebone Black板子，上电开机后能正常的从nand启动，我现在想用这块板子来跑StarterWare裸机程序，于是将boot下的从sd卡启动的MLO和一个app拷贝到已经格式化的sd卡，插入bbb的卡槽按住S2后上电，发现板子还是依然从nand启动，并没有检测到sd卡，请问一下我该怎么处理才能从sd卡启动呢？

我尝试清除是可以的，现在我有个问题，就是使用StarterWare带的nand-flash-writer该工具来烧写Beaglebone Black的Nand，使用CCS配合仿真器XDS能进入烧写流程，但是在烧写时都会失败，打印如下

实在是没办发了，想请教一下这是什么情况呢？万分感激！
