          Install gpiod

          sudo apt update
          sudo apt install gpiod
          Six command-line tools are available:

          * gpiodetect - list all gpiochips present on the system, their names, labels
                         and number of GPIO lines
          
          * gpioinfo   - list all lines of specified gpiochips, their names, consumers,
                         direction, active state and additional flags
          
          * gpioget    - read values of specified GPIO lines
          
          * gpioset    - set values of specified GPIO lines, potentially keep the lines
                         exported and wait until timeout, user input or signal
          
          * gpiofind   - find the gpiochip name and line offset given the line name
          
          * gpiomon    - wait for events on GPIO lines, specify which events to watch,
                         how many events to process before exiting or if the events
                         should be reported to the console

          sudo apt-get update
          sudo apt-get install nvidia-jetpack

          CUDA:

          終端命令行執行:nvcc -V,

          如果提示:bash: nvcc: command not found

          則先導入環境變量:

          $  export  PATH=/usr/local/cuda-11/bin:$PATH

          $  export  LD_LIBRARY_PATH=/usr/local/cuda-11/lib64:$LD_LIBRARY_PATH

          再執行nvcc -V即可。


          cudnn:

          終端命令行執行:

          $  dpkg  --list  | grep  cudnn


          opencv:

          終端命令行執行:

          $  dpkg  --list  | grep  libopencv


          tensorRT:

          終端命令行執行:

          $  pip   list   |  grep  tensorrt



          $ sudo apt-get install netplan.io -y

          $ cd /etc/netplan

          $ sudo vim 01-network-manager-all.yaml

          添加以下內容,添加完成過后保存并退出:
          network:
              version: 2
              renderer: NetworkManager
              ethernets:
                  eth0:  # 有線網卡的名字
                      mtu: 9000 #設置的mtu值,如果加上此項過后,需重啟系統才會生效。
                      addresses: [11.22.33.44/24]  # 填IP地址,后面有一個/24
                      dhcp4: no  # IPv4關閉自動獲取IP
                      dhcp6: no  # IPv6關閉自動獲取IP
                      gateway4: 11.22.33.2  # 設置網關,注意網關前3位跟IP地址前3位肯定是一致的。
                      nameservers:
                          addresses: [22.33.44.1,22.33.44.2] # 設置DNS解析主、備的服務器IP地址,如果有多個中間用逗號隔開,但不要有空格


          $ sudo  netplan apply或者直接重啟系統

          echo 255 > /sys/kernel/debug/tegra_fan/target_pwm  (L4T老版本

          或者

          echo 255 >/sys/devices/pwm-fan/target_pwm

          或者

          sudo  systemctl  stop  nvfancontrol.service 

          echo  255 > /sys/devices/platform/pwm-fan/hwmon/hwmon3/pwm1    (Jetpack5.*)

          運行如下命令:

          head -n1 /etc/nv_tegra_release

          在/etc/modprobe.d/bcmdhd.conf文件中加入配置內容后重啟系統生效:
          options bcmdhd op_mode=2
