推荐在win系统下进行烧录,方便SD卡的格式化和镜像软件的烧录。
(1)SD卡格式化软件下载:https://www.sdcard.org/downloads/formatter/sd-memory-card-formatter-for-windows-download/
(2)镜像烧录软件下载:https://etcher.balena.io/#download-etcher
(3)jetpack5.1.2 镜像下载:https://developer.nvidia.com/embedded/jetpack-sdk-512
先将SD卡进行格式化,然后将jetpack5.1.2镜像使用烧录软件实现系统烧录。
官网链接:https://developer.nvidia.com/sdk-manager
学习文档:https://docs.nvidia.com/jetson/archives/r34.1/DeveloperGuide/text/HR/JetsonDeveloperKitSetup.html
1、准备一台主机、待烧录的Jetson Orin Nano开发板、SD卡、数据线
2、在主机Ubuntu下载SDK Manager
3、通过数据线将主机和Orin 来连接,短接Nano(如果没有短接帽,使用钥匙也可以实现短接)
4、按照Manager流程烧录
【!!!文中采用 关闭开机启动项的方式 解决开机缓慢问题,非必要别动!!不然 系统 会崩!
一般情况下,采用 方式1 使用SD卡烧录系统的开机时间在一分钟以内,不需要解决开机缓慢问题】

Jetpack 5.1.2

# open环境变量:
vim ~/.bashrc #或者采用 source gedit ~/.bashrc
#在最后写入并保存:
export CUDA_HOME=/usr/local/cuda-11.4
export PATH=$PATH:$CUDA_HOME/bin
export LD_LIBRARY_PATH=/usr/local/cuda-11.4/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
#使其生效:
source ~/.bashrc
#查看是否生效:
cat /proc/driver/nvidia/version
nvcc -V
# ~/.bahrc文件中的内容还可以填:
export CUDA_HOME=/usr/local/cuda
export PATH=${CUDA_HOME}/bin:${PATH}
export LD_LIBRARY_PATH=${CUDA_HOME}/lib64:$LD_LIBRARY_PATH
```bash
将对应的头文件、库文件放到cuda目录。cuDNN的头文件在:/usr/include,库文件位于:/usr/lib/aarch64-linux-gnu。将头文件与库文件复制到cuda目录下:
cd /usr/include && sudo cp cudnn.h /usr/local/cuda/include
cd /usr/lib/aarch64-linux-gnu && sudo cp libcudnn* /usr/local/cuda/lib64
修改文件权限,修改复制完的头文件与库文件的权限,所有用户都可读,可写,可执行:
```bash
sudo chmod 777 /usr/local/cuda/include/cudnn.h /usr/local/cuda/lib64/libcudnn*
重新链接:
cd /usr/local/cuda/lib64
sudo ln -sf libcudnn.so.8.4.0 libcudnn.so.8
sudo ln -sf libcudnn_ops_train.so.8.4.0 libcudnn_ops_train.so.8
sudo ln -sf libcudnn_ops_infer.so.8.4.0 libcudnn_ops_infer.so.8
sudo ln -sf libcudnn_adv_infer.so.8.4.0 libcudnn_adv_infer.so.8
sudo ln -sf libcudnn_cnn_infer.so.8.4.0 libcudnn_cnn_infer.so.8
sudo ln -sf libcudnn_cnn_train.so.8.4.0 libcudnn_cnn_train.so.8
sudo ln -sf libcudnn_adv_train.so.8.4.0 libcudnn_adv_train.so.8
sudo ldconfig
测试cuDNN:
sudo cp -r /usr/src/cudnn_samples_v8/ ~/
cd ~/cudnn_samples_v8/mnistCUDNN
sudo chmod 777 ~/cudnn_samples_v8
sudo make clean && sudo make
./mnistCUDNN

dpkg -l | grep TensorRT
sudo vim ~/.bashrc
export PATH=/usr/src/tensorrt/bin:$PATH

注:
1、在使用SD卡镜像烧录时,会自带TensorRT,不需要用户后期再安装,如果import tensorrt找不到tensorrt,执行下面的命名试试:
# 安装JetPack组件包,其中包括了Cuda、CuDNN和TensorRT
sudo apt install nvidia-jetpack
2、资源有版本为8.2.3.0的tensorrt安装包whl。
