上述操作重复了N遍，换了USB接口还是这样。下载LINUX时，板子正常。不知道是什么原因，求大虾解答。

你使用的dnw版本是？天嵌的dnw吗？你使用usb下载→uboot还是eboot下载的？

用的DNW是论坛提供的EmbedSkyDownLoadTool1.3.9，USB下载用的是uboot。

你尝试下使用eboot选项，建议usb线使用我们官方的，或者质量好的，建议使用台式机机箱背后的usb口以确保供电

谢谢建议。
我是用的台式机机箱背后的usb口，USB线也是用的天嵌配套的。
前面烧写步骤保持不变，NK_Q43_3Serial_20100603.bin烧写采用EBOOT选项，出现如下错误：
Enter your selection: u

还是卡住了，屏幕一半白屏，一半logo。

你可以联系下销售索要一下EBOOT_Q43_debug_20120110.nb0试试

NK最新版本是NK_Q43_3Serial_20121205.bin

重装系统后，就好了

你说的是电脑还是开发板

重装电脑系统

我也试过重装系统，但还是解决不了，我的是3.5寸的屏幕；

来看看，新手也不会
