按下Ctrl+Alt+T打开终端，进入JetsonNano_DT_SPI_master目录，复制下面命令: 

cd JetsonNano_DT_SPI_master/
./run.sh

输入用户密码，脚本开始自动下载根文件系统包和R32包。

若出现解压文件包错误，则先安装bzip2的1.0.6-8.1版本和支持库，复制下面指令进行安装，否则忽略下面一条命令: 


sudo apt install bzip2=1.0.6-8.1 libbz2-1.0=1.0.6-8.1

下载根文件系统和R32包后，脚本自动替换设备树文件并写入根文件系统，接着界面提示Nano是否进入Recovery模式

此时应将跳帽置Recovery引脚，J48引脚，MicroUSB接入PC，使用DC头供电

在终端输入y确认

刷写成功后如下图所示

此时可拔掉Recovery跳帽，MicroUSB，将跳帽置于40Pin的19和21引脚准备做Loopback测试。

三、SPI测试


Ubuntu下使用Termius等软件连接JetsonNano终端，使用wget命令下载spi_dev_test.c文件，复制下面指令: 

wget https://raw.githubusercontent.com/raspberrypi/linux/rpi-3.10.y/Documentation/spi/spidev_test.c


104030a5v21sqd5t2t0tz0.png 

使用vim打开并修改spidev_test.c文件，将32行的"spidev1.1"修改成"spidev0.0"，不熟悉vim操作的用

户可参考 https://wiki.diustou.com/study/portal.php?mod=view&aid=598 进行学习

编译执行刚才修改好的spidev_test.c文件，复制下面命令: 

gcc -o spidev_test spidev_test.c
sudo ./spidev_test

至此Jetson Nano的spi0可以使用了，下面测试Pioneer600的OLED功能，复制下面命令下载Pioneer例程 

wget http://wiki.diustou.com/w/upload/a/ad/Pioneer600_code.7z

安装解压工具并解压刚才下载的Pioneer600_code.7z文件，复制下面命令 

sudo apt-get install p7zip
p7zip --uncompress Pioneer600_code.7z

解压后进入JetsonNano/OLED/python文件夹，复制下面命令令执行OLED显示:



cd JetsonNano/OLED/python/
sudo python3 waveshare.py

其中Pioneer600的OLED与JetsonNano硬件连接如下图所示

OLED引脚 JetsonNano Board引脚
+3.3V 1
GND 6
CS 24
RES 35
DC 36
SCK 23
MOSI 19

若未安装PIL库，OLED显示会失败，失败则先安装下面支持包，复制下面指令: 

sudo apt-get install python3-dev python3-setuptools libtiff5-dev zlib1g-dev libfreetype6-dev liblcms2-dev libwebp-dev libharfbuzz-dev libfribidi-dev  tcl8.6-dev tk8.6-dev python3-tk
sudo apt-get install python3-pip
sudo pip3 install pillow
