大佬，我想问一下如何在设备树中使能上电，在dev下看到ttyUSB*

wanglang

使用misc-upgrace按照小容量升级流程，写入extend分区后，会重启。

但是重启过程中，出现以下日志提示，并卡住，使得板子变板砖。

比如使用V853方案编译的镜像烧录之后，如何携带版本号呢？
我们知道Linux内核版本可以通过uname -a查看。

root@(none):/# uname -a
Linux (none) 4.9.191 #383 PREEMPT Wed Mar 13 09:56:09 UTC 2024 armv7l GNU/Linux

但是烧录固件的版本如何设置和查看呢？
比如我第一次烧录镜像，希望烧录之后固件本版：1.0.1(V3R2)。
然后我第二烧录，设置版本为 1.0.2(V4R1)。或者通过OTA升级为该版本。
请问这种版本号可以从哪里管理，从哪里读取呢？

wanglang

@dream @smbzd @fuzhikun @Alb702 @camperzzz 感谢各位。
是的，本质上是修改路由表和DNS，这里采用了一种简单方法。

判断当前的网络工作状态。如果是wifi wlan0网口工作, 判断 ping ip -I wlan0 当网口不通时候，刷新 usb0的网口 udhcpc -i usb0 ,会刷新route路由表和 usb0的DNS文件/etc/resolve.conf，使得usb0工作，并设置工作状态为4g usb0。
wifi_deman中设置wifi会自动重连，当wifi连接成功(账号连接或者断开重连)后。再进行一次wlan0的路由刷新和DNS刷新。切换为WIFI工作。
顺便，再route路由表中
虽然两个优先级Metric都是0，但是由于udhcpc刷新了route和DNS，所以只有排在前面的一个网口以及对应网关gateway到DNS中的一个网口会工作。

wanglang

在arm开发版中，有两张网卡，其中一张WIFI无线wlan0网卡，一张4G移动usb0网卡，两个网卡均可单独连接网络上网。但是同一时间只有一张卡能生效，且为最后一张udhcp启动的网卡。比如先启动了usb0网卡后，有网络。在启动wlan0有网络。使用的就是wlan0，当wlan0 wifi 断开之后，不会自动使用usb0网络，usb0网络也不通。

wifi使用SDK内置wifi_deman开启的，4g网络使用usb设备连接的。
如何像手机一样，有WIFI时候自动连接WIFI网络，WIFI网络端口后自动使用4G网络，且优先使用WIFI网络。

网卡如下

您好，请问如何在DTS中给ttyUSB设备使能上电重置呢？

wanglang

我目前接入了移远EC20模块做4g通信。目前硬件已经调通，可能进入系统后通过手动导出GPIO和拉高拉低GPIO给ec20供电。
我是否可以将这个调整到board.dts设备树中呢？
需要先将gpio_pwn拉高一秒后复位。或者将gpio_rst拉高后复位。我对于设备树不是很了解，新增gpio设备应该遵循什么规则呢？
