i.MX 6ULL 驱动开发 一：搭建开发环境
一、搭建编译环境
1、工具
工具 版本 开发板 正点原子 imx6ull 开发板 gcc gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabihf uboot uboot-imx-2016.03-2.1.0 linux linux-imx-4.1.15 2、搭建 tftp 服务器
ubuntu20.04 搭建tftp服务器_lqonlylove的博客-CSDN博客_ubuntu配置tftp服务器
3、搭建 nfs 服务器
ubuntu20.04 搭建NFS服务器_lqonlylove的博客-CSDN博客
二、配置编译工具链
1、版本选择
2、解压
sudo tar -vxf gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabihf.tar.xz- 1
解压后名字太长，更改 gcc 文件夹名：
onlylove@ubuntu:~/my/gcc$ ls gcc-linaro-4.9.4 gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabihf.tar.xz onlylove@ubuntu:~/my/gcc$- 1

- 3
3、配置
打开/etc/profile 以后，在最后面输入如下所示内容：
export PATH=$PATH:/home/onlylove/my/gcc/gcc-linaro-4.9.4/bin- 1
配置完后，重启主机。
4、验证

三、uboot
1、版本选择
因使用正点原子开发板，因此选择正点原子提供uboot版本。
2、解压
