请问下：
现在平台是EZSDK，制作SD卡就是使用一句话sudo ${EZSDK}/bin/mksdboot.sh --device /dev/sdb --sdk ${EZSDK}
但是，现在添加了一个设备驱动，并且生成了uImage ,，现在怎么制作SD卡，使得该设备驱动直接存在dev目录下？

Yang Yongsong，
你的设备驱动是编译在uImage里面的，还是module？如果是前者，直接替换之前SD卡里的uImage就可以了。如果是后者，需要将.ko文件复制到文件系统下，在linux启动后加载。
是在uImage中的，但是只替换这个好像启动不了，一直卡在加载uImage这，请问下还需要修改哪些地方吗

修改后直接卡死在这啦，
你好，
Kernel在加载过程中卡死，应该是你添加的驱动的问题吧，你在你添加的驱动里面添加些打印，看看问题在哪里。
