一、前言
PC环境：Ubuntu18.04.2 LTS

JetsonNano环境:Ubuntu 18.04 LTS
Jetson Nano的40Pin接口SPI功能默认并未启用，需手动修改设备树文件后写入根文件系统。<b>因使用虚拟机刷写Nano易变砖</b>，不建议用虚拟机。
二、重写设备树

使用非官方脚本文件来刷设备树，在PC端中点击图中Download ZIP下载脚本文件，github地址为https://github.com/rt-net/JetsonNano_DT_SPI，或点击右边附件下载<a class="attach" href="portal.php?mod=attachment&amp;id=1586" target="_blank">JetsonNano_DT_SPI-master.zip

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:



<syntaxhighlight lang="python">
sudo apt install bzip2=1.0.6-8.1 libbz2-1.0=1.0.6-8.1</syntaxhighlight>

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


[[File:102110gy1349jppe431szb.png]]


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


[[File:103737ytv7s573fy4nyae0.png]]


在终端输入y确认



[[File:103756j2gi3ll6msxseug2.png]]


刷写成功后如下图所示




[[File:103815vjz143rqb8li5jtl.png]]

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:

<syntaxhighlight lang="python">
wget https://raw.githubusercontent.com/raspberrypi/linux/rpi-3.10.y/Documentation/spi/spidev_test.c</syntaxhighlight>


[[File: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
