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:

终端命令行执行:nvcc -V,

如果提示:bash: nvcc: command not found

则先导入环境变量:

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

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

再执行nvcc -V即可。


cudnn:

终端命令行执行:

$  dpkg  --list  | grep  cudnn


opencv:

终端命令行执行:

$  dpkg  --list  | grep  libopencv


tensorRT:

终端命令行执行:

$  pip   list   |  grep  tensorrt



$ sudo apt-get install netplan.io -y

$ cd /etc/netplan

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

添加以下内容,添加完成过后保存并退出:
network:
    version: 2
    renderer: NetworkManager
    ethernets:
        eth0:  # 有线网卡的名字
            mtu: 9000 #设置的mtu值,如果加上此项过后,需重启系统才会生效。
            addresses: [11.22.33.44/24]  # 填IP地址,后面有一个/24
            dhcp4: no  # IPv4关闭自动获取IP
            dhcp6: no  # IPv6关闭自动获取IP
            gateway4: 11.22.33.2  # 设置网关,注意网关前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] # 设置DNS解析主、备的服务器IP地址,如果有多个中间用逗号隔开,但不要有空格


$ sudo  netplan apply或者直接重启系统

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.*)

运行如下命令:

head -n1 /etc/nv_tegra_release

在/etc/modprobe.d/bcmdhd.conf文件中加入配置内容后重启系统生效:
options bcmdhd op_mode=2
