- 文章假定读者一定程度了解 linux 基础知识
- 文章来源于《嵌入式linux完全开发手册》- IMX6ull 开发板从零移植篇
区别在于:本文描述从各个网站（官网）下载最新 ubuntu、交叉编译器、uboot、kernel、buildroot 从零开始构建，更接近实际工程环境
(可同时交叉参阅两份文章)一、关于 ubuntu
- 下载安装最新桌面 LTS 版本 ubuntu
- 正常步骤安装（参考网络其它文章）
-
几个关键的设置
- 磁盘大小：60GB 以上
- 网络连接：使用桥接网络（复制网络连接状态）[路由器连接开发板和电脑]
二、关于交叉工具链
1、下载
ARM开发者中心下载交叉编译工具链
host 为 linux 👉 `x86_64 linux`
imx6ul 为 arm_A7 架构 👉 `AArch32`
imx6ul 支持硬件浮点 👉 `hard fllat`
需支持 linux 操作系统 👉 `none-linux`2、配置
解压缩
tiansong@tiansong:~/100ask_imx6ull_pro$ ls

tiansong@tiansong:~$ vim ~/.bashrc

# 使环境变量在当前终端生效
tiansong@tiansong:~/100ask_imx6ull_pro$ source ~/.bashrc验证是否配置成功

1、下载
# 下载
tiansong@tiansong:~/100ask_imx6ull_pro$ tiansong@tiansong:~/100ask_imx6ull_pro$ git clone https://source.codeaurora.cn/external/imx/uboot-imx

# 查看仓库所有分支
tiansong@tiansong:~/100ask_imx6ull_pro$ cd uboot-imx/
tiansong@tiansong:~/100ask_imx6ull_pro/uboot-imx$ git branch -a
...
remotes/origin/imx_v2020.04_5.4.70_2.3.0
...
# 切换到 imx 最新分支
tiansong@tiansong:~/100ask_imx6ull_pro/uboot-imx$ git checkout remotes/origin/imx_v2020.04_5.4.70_2.3.0
Updating files: 100% (11834/11834), done.
Note: switching to 'remotes/origin/imx_v2020.04_5.4.70_2.3.0'.
You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.
If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:
git switch -c <new-branch-name>
Or undo this operation with:
git switch -
Turn off this advice by setting config variable advice.detachedHead to false

MLK-25878: imx8: scu: Increase sendmsg timeout for SCFW MU
Similar to receivemsg, sendmsg function should also
use 1 sec timeout for MU communication with SCFW.

}3、配置及编译
安装环境依赖
sudo apt install make
sudo apt install bison flex生成 .config 文件
tiansong@tiansong:~/100ask_imx6ull_pro/uboot-imx$ pwd
/home/tiansong/100ask_imx6ull_pro/uboot-imx
tiansong@tiansong:~/100ask_imx6ull_pro/uboot-imx$ make 100ask_imx6ull_pro_emmc_defconfig图形化配置
tiansong@tiansong:~/100ask_imx6ull_pro/uboot-imx$ make menuconfig确认板级支持, 目录项
