Install gpiod
sudo apt update sudo apt install gpiodSix 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

此BSP补丁仅适用于品立自研系列产品，详细操作方法请见README文档，
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
