关于linux:进行中-从零搭建-100askimx6ullpro-开发板运行环境

jiezi
  • 文章假设读者肯定水平理解 linux 基础知识
  • 文章来源于《嵌入式 linux 齐全开发手册》- IMX6ull 开发板从零移植篇
区别在于: 本文形容从各个网站（官网）下载最新 ubuntu、穿插编译器、uboot、kernel、buildroot 从零开始构建，更靠近理论工程环境
(可同时穿插参阅两份文章)

一、对于 ubuntu

  • 下载安装最新桌面 LTS 版本 ubuntu
  • 失常步骤装置（参考网络其它文章）

  • 几个要害的设置

    • 磁盘大小：60GB 以上
    • 网络连接：应用桥接网络（复制网络连接状态）[路由器连贯开发板和电脑]

二、对于穿插工具链

1、下载

ARM 开发者核心下载穿插编译工具链

host 为 linux 👉 `x86_64 linux`
imx6ul 为 arm_A7 架构 👉 `AArch32`
imx6ul 反对硬件浮点 👉 `hard fllat`
需反对 linux 操作系统 👉 `none-linux`

2、配置

解压缩

tiansong@tiansong:~/100ask_imx6ull_pro$ ls
arm-gnu-toolchain-11.3.rel1-x86_64-arm-none-linux-gnueabihf.tar.xz

tiansong@tiansong:~/100ask_imx6ull_pro$ tar -xvf arm-gnu-toolchain-11.3.rel1-x86_64-arm-none-linux-gnueabihf.tar.xz

tiansong@tiansong:~/100ask_imx6ull_pro$ ls
arm-gnu-toolchain-11.3.rel1-x86_64-arm-none-linux-gnueabihf  arm-gnu-toolchain-11.3.rel1-x86_64-arm-none-linux-gnueabihf.tar.xz

设置环境变量

tiansong@tiansong:~$ vim ~/.bashrc

# 在文件开端追加
export ARCH=arm
export CROSS_COMPILE=arm-none-linux-gnueabihf-
export PATH=$PATH:/home/tiansong/100ask_imx6ull_pro/arm-gnu-toolchain-11.3.rel1-x86_64-arm-none-linux-gnueabihf/bin

# 使环境变量在以后终端失效
tiansong@tiansong:~/100ask_imx6ull_pro$ source ~/.bashrc

验证是否配置胜利

三、对于 uboot

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
tiansong@tiansong:~/100ask_imx6ull_pro$ ls
arm-gnu-toolchain-11.3.rel1-x86_64-arm-none-linux-gnueabihf  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

HEAD is now at 62a81128c0 MLK-25878: imx8: scu: Increase sendmsg timeout for SCFW MU

# 确认是否却换胜利
tiansong@tiansong:~/100ask_imx6ull_pro/uboot-imx$ git log -1
commit 62a81128c07c3efc123039f796ffc43b4eacbf04 (HEAD, origin/imx_v2020.04_5.4.70_2.3.0)
Author: Nitin Garg <nitin.garg@nxp.com>

    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

装置环境依赖

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

图像化配置

tiansong@tiansong:~/100ask_imx6ull_pro/uboot-imx$ make menuconfig

确认板级反对, 目录项 ARM architecture

确认默认的设施树，目录项 Boot media –> Device Tree Control

使能 SD/EMMC 启动, 目录项 Boot media

使能随机 MAC 地址生成, 目录项 Networking support

网卡反对

  • 目录项 Device Drivers/Network device support

  • 目录项 Device Drivers/Ethernet PHY(physical media interface) support

编译

tiansong@tiansong:~/100ask_imx6ull_pro/uboot-imx$ make -j12
