Install gpiod

sudo apt update
sudo apt install gpiod

* 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(zhí)行：nvcc -V，

如果提示：bash: nvcc: command not found

則先導(dǎo)入環(huán)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(zhí)行nvcc -V即可。

cudnn：

終端命令行執(zhí)行：

$  dpkg  --list  | grep  cudnn

opencv:

終端命令行執(zhí)行：

$  dpkg  --list  | grep  libopencv

tensorRT:

終端命令行執(zhí)行：

$  pip   list   |  grep  tensorrt

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(yùn)行如下命令：

head -n1 /etc/nv_tegra_release
