| 可以了，原来是代码有点问题，现在可以完美的ping主机了 |
| 刚刚我又测试了一下。用你们刷机的系统 连接路由器，可以PING通外网，把笔记本也连上路由器，开发板可以PING通笔记本。但是假如把开发板直接用网线连接上笔记本，那么就PING不通笔记本了。这是什么原因。笔记本一直设置的都是手动IP未变过 |
| 我用你们刷机的系统 PING通了百度，也可以PING路由器，可是我把网线插到笔记本上，就PING不了笔记本》这是为什么? |

| 板子已经返修回来了，售后说刷机后就能ping了，请问你们的系统ping是怎么用？ |
13828866810 发表于 2022-12-5 16:42 那你找一下你购买开发板的客服，然后寄回来看一下 |
| 你们公司给达内的源码，达内再给我们的源码。其他人的都ping上了，我的板子ping不上 |
13828866810 发表于 2022-12-5 15:19 固件是你自己编译的还是我们公司提供的 |
| 启动文件uboot和Linux-QT系统uImage，还有根文件 |
13828866810 发表于 2022-12-5 12:38 你烧录的系统是Linux-Qt还是Ubuntu |
| 进入linux下，插上路由器，Ping路由器也不通，ping外网也不通 |
| 你再看下，究竟是哪里的问题？网卡 eth0是在的，eth1没有。为什么我配置了eth0，还是ping不通呀 |

13828866810 发表于 2022-12-5 10:02 你跑的是什么系统？ |
| ping 板子的ip |
| 主机可以ping通虚拟机，虚拟机也可以p ing通主机。就是板子ping谁都不通，就停在那里了 |
| ifconfig有ip地址，板子pin g不了外网，我不联外网，就主机和板子之间通过网线连接，PiNg不通。板子怎么pin自己？ |
| ifconfig查看是否有IP，如果有IP的话，使用的是外网可以尝试ping www.baidu.com,如果使用的是局域网，试试ping自己看看能不能ping通 |
