最近把树莓派3B出了买了块OrangePi Zero2，正要折腾的时候发现OrangePi的官方镜像不像树莓派一样有个方便修改的boot.txt，而且官方也不像树莓派一样有一个能修改开机配置的烧录器。于是乎基本都是建议你开机用ttl或者连有线来配置wifi。但是这样很麻烦，非常不利于我这种一天格几次盘的折腾选手，于是我就开始琢磨有没有第一次开机就自动连wifi的方法。
经过一番搜寻，我发现boot里面有个orangepi_first_run.txt.template文件(在armbian里是armbian_first_run.txt.template)里面大概长这样：
#-----------------------------------------------------------------
# Orange Pi first run configuration
# Set optional end user configuration
# - Rename this file from /boot/orangepi_first_run.txt.template to /boot/orangepi_first_run.txt
# - Settings below will be applied only on 1st run of Orange Pi
#-----------------------------------------------------------------
#-----------------------------------------------------------------
# General:
# 1 = delete this file, after first run setup is completed.
FR_general_delete_this_file_after_completion=1
#-----------------------------------------------------------------
#Networking:
# Change default network settings
# Set to 1 to apply any network related settings below
FR_net_change_defaults=0
# Enable WiFi or Ethernet.
# NB: If both are enabled, WiFi will take priority and Ethernet will be disabled.
FR_net_ethernet_enabled=1
FR_net_wifi_enabled=0
#Enter your WiFi creds
# SECURITY WARN: Your wifi keys will be stored in plaintext, no encryption.
FR_net_wifi_ssid='MySSID'
FR_net_wifi_key='MyWiFiKEY'
# Country code to enable power ratings and channels for your country. eg: GB US DE | https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2
FR_net_wifi_countrycode='GB'
#If you want to use a static ip, set it here
FR_net_use_static=0
FR_net_static_ip='192.168.0.100'
FR_net_static_mask='255.255.255.0'
FR_net_static_gateway='192.168.0.1'
FR_net_static_dns='8.8.8.8 8.8.4.4' #2 entries max, seperated by a space.
#-----------------------------------------------------------------
诶哟这不就来了吗，填完信息改完配置我才发现，windows不支持ext4，没法编辑img文件里的内容。那就只能通过wsl来编辑这个img了。
这里要用到parted这个包来读取img的起始地址，wsl的系统默认是没有的，需要安装一下。
