１、新建SSH

boot 硬盘中新建 　SSH　空白无后缀名文件

２、添加Wi-Fi　

• 文件名：wpa_supplicant.conf
• 格式：txt文本

country=CN
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
ssid="raspberry"
psk="bi4jgm"
}

network={
ssid="家里Wi-Fi热点的名字"
psk="Wi-Fi密码"
}

network={
ssid="单位Wi-Fi热点的名字"
psk="Wi-Fi密码"
}

3、设置64位 设置防止树莓派4不接入显示器无法启动的现象

在boot 驱动器根目录找到 config.txt

最后写入

arm_64bit=1

hdmi_group=2
hdmi_mode=35

取消#

hdmi_force_hotplug=1

#bi4jgm
# For more options and information see
# http://rpf.io/configtxt
# Some settings may impact device functionality. See link above for details

# uncomment if you get no picture on HDMI for a default “safe” mode
#hdmi_safe=1

# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan
#disable_overscan=1

# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
#overscan_left=16
#overscan_right=16
#overscan_top=16
#overscan_bottom=16

# uncomment to force a console size. By default it will be display’s size minus
# overscan.
#framebuffer_width=1280
#framebuffer_height=720

# uncomment if hdmi display is not detected and composite is being output
hdmi_force_hotplug=1

# uncomment to force a specific HDMI mode (this will force VGA)
#hdmi_group=1
#hdmi_mode=1
hdmi_group=2
hdmi_mode=35

# uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes
#hdmi_drive=2

# uncomment to increase signal to HDMI, if you have interference, blanking, or
# no display
#config_hdmi_boost=4

# uncomment for composite PAL
#sdtv_mode=2

#uncomment to overclock the arm. 700 MHz is the default.
#arm_freq=800

# Uncomment some or all of these to enable the optional hardware interfaces
#dtparam=i2c_arm=on
#dtparam=i2s=on
#dtparam=spi=on

# Uncomment this to enable infrared communication.
#dtoverlay=gpio-ir,gpio_pin=17
#dtoverlay=gpio-ir-tx,gpio_pin=18

# Additional overlays and parameters are documented /boot/overlays/README

# Enable audio (loads snd_bcm2835)
dtparam=audio=on

[pi4]
# Enable DRM VC4 V3D driver on top of the dispmanx display stack
dtoverlay=vc4-fkms-v3d
max_framebuffers=2

[all]
#dtoverlay=vc4-fkms-v3d

4、SSH

1、扩展硬盘空间

sudo su

raspi-config

选 6 Advanced Options 1 Expand Filesystem

2、启动vncserver 设置后台自动启动 sudo systemctl enable vncserver-x11-serviced.service

5、修改运行缓存解决内存不足1G建议设置大点，内存大了设置小点

sudo nano /etc/dphys-swapfile

CONF_SWAPSIZE=2048

6、更改软件源

方法1

sudo echo “deb http://mirrors.tuna.tsinghua.edu.cn/raspbian/raspbian/ buster main non-free contrib rpi
deb-src http://mirrors.tuna.tsinghua.edu.cn/raspbian/raspbian/ buster main non-free contrib rpi
“>/etc/apt/sources.list

方法2

sudo nano /etc/apt/sources.list

deb http://mirrors.tuna.tsinghua.edu.cn/raspbian/raspbian/ buster main non-free contrib
deb-src http://mirrors.tuna.tsinghua.edu.cn/raspbian/raspbian/ buster main non-free contrib

把 /etc/apt/sources.list.d/raspi.list 文件也替换成下面的内容：

deb http://mirrors.tuna.tsinghua.edu.cn/raspberrypi/ buster main ui

7、更新系统

#更新软件源列表 sudo apt-get update

#更新软件版本 sudo apt-get upgrade sudoapt-get dist-upgrade

#更新系统内核sudo rpi-update
