一、安装USB驱动

相关页面：https://www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers
下载链接：CP210x Universal Windows Driver v11.0.0
https://www.silabs.com/documents/public/software/CP210x_Universal_Windows_Driver.zip

二、Ubuntu环境配置

1、安装git环境

sudo apt-get install git

2、获取视频教程

git clone https://e.coding.net/weidongshan/01_all_series_quickstart.git

3、下载代码

（1）配置git邮箱和用户
book@100ask:~$ git config --global user.email "user@100ask.com"
book@100ask:~$ git config --global user.name "100ask"
（2）IMX6ULL MINI EMMC版同步代码
book@100ask:~$ git clone https://e.coding.net/codebug8/repo.git
book@100ask:~$ mkdir -p 100ask_imx6ull_mini-sdk && cd 100ask_imx6ull_mini-sdk
book@100ask:~/100ask_imx6ull_mini-sdk$ ../repo/repo init \
-u https://gitee.com/weidongshan/manifests.git -b linux-sdk \
-m imx6ull/100ask_imx6ull_mini_linux4.9.88_release.xml --no-repo-verify
book@100ask:~/100ask_imx6ull_mini-sdk$ ../repo/repo sync -j4

4、IMX6ULL MINI EMMC版配置交叉编译工具链

vim ~/.bashrc
末尾添加：
export ARCH=arm
export CROSS_COMPILE=arm-buildroot-linux-gnueabihf-
export PATH=$PATH:/home/book/100ask_imx6ull_mini-sdk/ToolChain/arm-buildroot-linux-gnueabihf_sdk-buildroot/bin
使用下方生效环境变量
source ~/.bashrc
使用下方命令查看版本：
arm-buildroot-linux-gnueabihf-gcc -v
测试环境变量：
book@100ask:~$ echo $ARCH
arm
book@100ask:~$ echo $CROSS_COMPILE
arm-buildroot-linux-gnueabihf-
