    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
