tinkerboard 2s网络间歇性中断重连
(为了高效,请按如下格式提问)硬件主板型号:tinkerboard 2s
固件名称/系统版本:Debian
自编的或固件下载地址:官方镜像
问题描述及复现步骤:
1、采用板子上的RJ45网络接口,使用网线和PC连接,采用ping进行网络通断测试,linux上的网络一段时间后就自动断开,过段时间又自动连上了,希望能够持续连接不断开,如何处理,问题又是什么?
2、安装系统后,采用40pin上的串口与另外设备连接,提示串口无法连接,如何解决?
1, 你是板子与PC直连?那你要用直联网线,水晶头接法不一样,可以百度一下
2,你说提示串口无法连接,是在哪提示,具体硬件接线是什么? peter 发表于 2023-11-30 12:25

1、用相同的网线,试过两台PC之间互联,是没有问题的,如果是因为交叉线和直连线的问题,不应该是直接无法接通,而不是间歇性中断把
2、串口是与一个单片机的串口进行连接,用PC是可以通的,已经验证了可行性,采用板子就不行,打印的日志里面显示串口打印失败 peter 发表于 2023-11-30 12:25

今天又做了一条直连的网线,连接依旧是间歇性中断
下面三图为测试通断情况
第一图,连接上自动断开
第二图,查看连接,系统自动切换到断开模式
第三图,系统又自动连接上了
1、建议由tinker提供dhcp服务,tinker作为路由,pc作为客户端,做数据传输测试看看
2、串口问题,先确认tinker-config是否开启对应uart0或uart4,然后确认接线pin脚是否正确,然后就是确定一下权限问题,有没有串口操作权限,如果没有,手动 chmod开一下权限 tinker 开DHCP功能
安装方法:
1、sudo apt install dnsmasq
2、解压 Lan_dhcp.zip
3、chmod 755 Enable_Lan_DHCP.sh
4、./Enable_SoftAP.sh 你的是Debian10的系统吗 我是用网线连接测试没有出现断线的情况
