明白，谢谢

在NEO中/etc/config/network中switch是禁止的

config interface 'lan'
option force_link '1'
option ifname 'eth0'

config switch
option name 'switch0'
option reset '1'
option enable_vlan '0'

但是在网络设备列表中，还是会出现eth0.1

ifconfig

eth0 Link encap:Ethernet HWaddr 9C:65:F9:20:B5:F5
UP BROADCAST RUNNING MULTICAST MTU:1500

eth0.1 Link encap:Ethernet HWaddr 9C:65:F9:20:B5:F5
UP BROADCAST RUNNING MULTICAST MTU:1500

它对应的是什么呢？

wifi功能正常，这段代码是最近 2月9日，加到master分支上

增加1000-esw_rt3052-update-wan-ip.patch

应该只是一条调试信息，容易误解以为系统检查到为空指针

https://wiki.widora.cn/firmware 里的固件没有这个提示，

我重新编译的目的是，按照下面的链接增加RNDIS的支持，
https://sns.widora.cn/topic/612/mt7688-air720-4g简单测试
但是我手里的是华为ME909S模块，它需要增加USB serial的支持，以便通过命令启动RNDIS拨号，但是你附件的版本，还少了一个驱动kmod-usb-serial-option，导致串口不能识别，总之增加需要以下驱动，

kmod-usb-net  
kmod-usb-net-rndis
kmod-usb-serial
kmod-usb-serial-wwan
kmod-usb-serial-option

只是我生成的版本有运行是上面的出错提示，版本是直接从Git取下来，插入模块后的提示如下，模块可以识别，但是只是一次，后面再也不能识别了，可能是我的miniPCI转USB硬件出的问题，因为PC也再不能识别这个模块了，我会重新买一个，再试一下

用原来1.09的版本是没有这个提示的

从Git上取最新的openwrt_widora的master分支， 重新编译，下载到bit5.1+kit后，系统检测到网线插拔时，会报如下提示

[ 21.590000] rt305x-esw 10110000.esw: link changed 0x01

请问，这是什么问题，会有什么影响吗？

现在已经有宽温版的BIT， 请问有没有计划推出工业板的BIT（-40~+85）， 类似EMBEST推出的BeagleBone Black 工业版，这样用户可以根据项目环境进行选择，而无需重新选择平台，（如果MT7688无法符合要求， 是否有其他替代选择）

@mango said in 这次BIT模块的金手指版本更适合量产了:

MT7628DAN

BIT3/4是否有支持2个以上网口的底板，有不少项目要求支持多网口，做为链路备份

@mango said in MT7688对64MB SPI FLASH的支持？:

7688

明白，谢谢
