          sudo dmesg > log.txt
          

          这个命令会产生一个log.txt文件,你找个u盘,插到tx2上,把log.txt拷出来,然后贴到这个帖子下面,我看看。

            @hxm 如果你操作不熟悉,可以试着在tx2上面装一下todesk,我远程操作一下试试。

                你的系统看起来一直在尝试dhcp功能,不知你环境为何没有支持dhcp的路由器?
                可以重新重新上电,启动之后不要耽误时间,再搞一个log.txt么?

                    从启动日志来看,这个不是我们给更新过的系统。

                    你有没有给系统装其他的启动盘,比如硬盘之类的?

                          @hxm 把硬盘去掉就可以了。
                          你这个硬盘是个启动盘。烧写的时候你说如果用不到,就不需要接硬盘。现在系统是在tx2本身自带的EMMC中的。
                          如果你开发程序需要硬盘做扩大存储,建议你把硬盘接到电脑上重新格式化一下。或者更改tx2的系统启动盘优先级,改为emmc有限。——跟电脑改启动盘的方法类似。

                                你这个启动日志还是不对啊。

                                刚才这个日志是断电,拔掉硬盘之后,重新上电输出的吗?
                                有没有做过类似什么系统恢复的操作? 或者看没看到过系统recovery的提示?
