制作SD卡一键烧写Android 4.2不成功（附COM0打出的log）
1. 做卡：按照20140919资料的手册，使用8G 闪迪 SD卡，使用工具HPUSBFW.EXE，在Win7 64系统的笔记本，用笔记本自带的SD卡槽。先用HPUSBFW.EXE将SD卡格式化，然后将Android4.2的uImage，ubi.img（256M），MLO（256M），u-boot.img（256M），logo.bmp拷贝到SD卡。2. 烧写系统：将SD卡插入OK335xD开发板的SD插口，将boot拨码开关拨为1ON 2ON，打开开发板电源，开始烧写，但从debug串口输出的信息看几十秒后debug信息卡住，开发板LCD在显示完logo.bmp后没有任何反应了，此时仍会看到核心板的led不停闪烁，但是led4-7没有流水灯效果。从debug串口打出的debug信息如下：

3. 初步从debug信息看像是问题出在SD卡只有部分能使用，于是又用SD卡烧写Android2.3系统试一下，还是同样的问题。但是再用SD卡烧写StarterWare编译后的裸机程序，运行正常。然后对SD卡用同样的步骤重新做卡，还是出现这个问题。
因此还请飞凌技术支持帮看下具体是什么原因？应当如何解决呢？
谢谢！
肯定是文件系统那块出错了，是不是加载地址错了。在uboot里面用printf把一般变量值打出来我看看 你用的MLO（256M），u-boot.img（256M），是错误的，拷贝batch目录里的同名文件 是用于sd卡烧写
