## 图文详解Jetson TK1平台搭建
在[《NVIDIA Jetson TK1学习与开发(一)》](http://blog.csdn.net/frd2009041510/article/details/41901239)和[《NVIDIA Jetson TK1学习与开发(二)》](http://blog.csdn.net/frd2009041510/article/details/41912775)中已经对TK1的基本资源进行了简单介绍,并且推荐了一些很有用的网址供大家学习。本文将图文详解Jetson TK1平台的搭建。
### 1、开箱第一步
开箱后进入唯一的目录下,
![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-05-07_572d616b26a33.jpg)
会看到installer.sh,在当前路径执行以下命令:
~~~
sudo ./installer
~~~
(注意:此命令只能执行一次)
重启,
~~~
sudo reboot
~~~
重启后进入开机登陆界面,账号和密码均是:ubuntu
### 2、平台开发的选择
一般来说,对嵌入式的开发有两种选择,原生编译(native compilation)和交叉编译(cross-compilation)。
所谓原生编译,就是在目标板上直接运行自己的代码,以TK1为例,就是说在TK1目标板上编译代码;所谓交叉编译,这也是我们大多数采用的编译方法,简单来说就是在台式机上编译,然后挂载在目标板上运行的方式。
对于开发TK1,推荐使用原生编译。
### 3、下载并安装CUDA包
下载安装包:[https://developer.nvidia.com/cuda-toolkit-60](https://developer.nvidia.com/cuda-toolkit-60)
![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-05-07_572d616b4fe0a.jpg)
(注意:下载的版本要与TK1的CUDA Driver版本一致,否则后面的samples无法执行。)
下载后如下图所示:

安装方法:
![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-05-07_572d616b8d162.jpg)
~~~
sudo dpkg -i xxx.deb
~~~
### 4、更新apt-get
![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-05-07_572d616bafe95.jpg)
~~~
sudo apt-get update
~~~
### 5、安装samples和toolkit
![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-05-07_572d616bc3f56.jpg)
![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-05-07_572d616bd3edc.jpg)
~~~
sudo apt-get install cuda-samples-6-0
sudo apt-get install cuda-toolkit-6-0
~~~
### 6、设置当前用户下可以访问GPU
![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-05-07_572d616be71c4.jpg)
~~~
sudo usermod -a -G video $USER
~~~
### 7、修改环境变量
![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-05-07_572d616c05539.jpg)
~~~
cd
vim .bashrc
~~~
在最后一行加上:
![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-05-07_572d616c19dfc.jpg)
~~~
export PATH=/usr/local/cuda-6.0/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda-6.0/lib:$LD_LIBRARY_PATH
~~~
最后不要忘记执行下面的命令:
![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-05-07_572d616c2b57f.jpg)
~~~
source .bashrc
~~~
### 8、查看编译环境是否安装成功
![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-05-07_572d616c3c2ce.jpg)
~~~
cd /usr/local/cuda
nvcc -V
~~~
从图中可以看到已经成功安装了CUDA6.0了。![大笑](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-01-19_569e21abc5518.gif)
### 9、编译与运行例程
查看当前目录中是否有samples:
![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-05-07_572d616c549ad.jpg)
~~~
ll
~~~
(注意是字母l。)
复制samples:
![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-05-07_572d616c711d0.jpg)
~~~
cuda-install-samples-6.0.sh /home/ubuntu/
~~~
然后,
~~~
cd
ls
~~~
可以看到NVIDIA_CUDA-6.0_Samples。
![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-05-07_572d616c82d99.jpg)
最后,
~~~
make
~~~
![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-05-07_572d616c97bb1.jpg)
make完成后,可以在...NVIDIA_CUDA-6.0_Samples/bin/armv7/linux/release/gnueabihf/下可以看到编译成功的可执行文件。
![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-05-07_572d616cb162f.jpg)
### 10、示例演示
在...NVIDIA_CUDA-6.0_Samples/bin/armv7/linux/release/gnueabihf/路径下完成已提供的例子即可。
以下提供两个例子,效果截图如下所示:
![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-05-07_572d616cc9866.jpg)
![](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-05-07_572d616cecf63.jpg)
至此,整个平台已经搭好,剩余的就是靠自己了。![吐舌头](https://docs.gechiui.com/gc-content/uploads/sites/kancloud/2016-03-22_56f0e98bbe0df.gif)
