CB2-uboot2020+linux6-卡启动篇

Andy201

Cubieboard2 经典永不过时，装了个主线6.0 + u-boot2020，终于可以告别全志万年不变的 linux3.4 了，全部上最新配置。

本帖记录 CB2-uboot2020+linux6-卡启动篇，将数据都写进 SD卡里，将 SD卡插入 CB2 板上启动。

硬件要求：

• CubieBoard2 板子 x1
• 读卡器和容量大于 4G 的 micro SD 卡 x1 (也叫 TF 卡),建设使用闪迪或金士顿的 Class 10 卡
• 主机一台
• TTL 串口线或者使用显示器及鼠标键盘进入系统控制台
  

软件要求：

• 主机操作系统:请使用 Ubuntu16.04 64 位操作系统（或更往上版本）
• 安装交叉编译环境：gcc version 7.5.0 (Linaro GCC 7.5-2019.12)
• qemu
• debootstrap
  

   

卡启动流程：
   上电——启动bootloader——启动内核——加载rootfs

卡启动所需文件：

• u-boot-sunxi-with-spl.bin
• sun7i-a20-cubieboard2.dtb
• zImage
• rootfs
• boot.scr
  

u-boot-sunxi-with-spl.bin 生成过程：

• 下载 u-boot 源码
• 切换分支到 v2020.01 （自行选择，在这里我用的是这个分支）
• 无需修改代码，直接编译
  

1. # u-boot 源码也提供两个仓库地址，任选一个即可
   
2. # github 仓库
   
3. git clone https://github.com/u-boot/u-boot.git
   
4. # gitee 镜像仓库
   
5. git clone https://gitee.com/mirrors/u-boot.git

复制代码

    注意：编译期间缺失的工具，工具报错打印提示自行安装。
     
     至此，u-boot-sunxi-with-spl.bin 已生成。


sun7i-a20-cubieboard2.dtb 和 zImage 生成过程：

• 下载主线内核源码
• 切换分支至 v6.1-rc8
• 无需修改代码，直接编译
  

1. # linux 源码仓库在 gitlab、github 上由 Linus Torvalds 维护
   
2. git clone https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
   
3. git clone https://github.com/torvalds/linux.git
   
4. 
   
5. # 由于 github 连接不稳定等原因，我们可以通过其它方式获取源码 —— 由 Gitee 官方
   
6. # 提供的 Linux 源码的镜像仓库，每天同步一次。
   
7. git clone https://gitee.com/mirrors/Linux.git
   
8. 
   
9. # 目前（2024.9.13）最新的 v6.1 版本为 v6.1-rc8，所以这里选择 v6.1-rc8 版本。
   
10. # 查看内核版本分支
    
11. git branch -a       # 查看所有分支
    
12. git fetch --tags    # 获取最新标签
    
13. git tag | grep v6   # 查看并筛选标签名
    
14. # 根据标签创建分支
    
15. git checkout tags/v6.1-rc8

复制代码

1. #在 arch/arm/configs/ 目录下有许多开发板的预定义配置文件，这里我们选择 Allwinner Cubieboard2 的 sunxi_defconfig
   
2. #以 sunxi_defconfig 为基础，生成 .config 配置文件
   
3. 
   
4. make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- sunxi_defconfig
   
5. 
   
6. ......
   
7. #
   
8. # configuration written to .config
   
9. #

复制代码

1. #编译菜单项配置（这是一个需要不断调试的枯燥工作）
   
2. make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- menuconfig

复制代码

1. #开始编译
   
2. make -j$(nproc) ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- zImage dtbs
   
3. ......
   
4.   OBJCOPY arch/arm/boot/zImage
   
5.   Kernel: arch/arm/boot/zImage is ready

复制代码

   
     注意：kernel 可能会编译报错，记录如下问题

     
     至此，zImage 和 sun7i-a20-cubieboard2.dts 已生成。


根文件系统 rootfs 生成过程：

• 下载根文件系统包
• 配置根文件系统 rootfs
• 备份打包 rootfs
  

1. ## man debootstrap ：
   
2. # --no-check-gpg ：Disables checking gpg signatures of retrieved Release files.
   
3. #
   
4. # 从 man 的示例 “debootstrap stretch ./stretch-chroot http://deb.debian.org/debian” 可知：
   
5. # 这里允许自定义下载源，官方的地址已经不支持 wheezy 版本，这里通过指定阿里源来指定 debian 版本为 fullseye 或 bookworm
   
6. #
   
7. debootstrap --foreign --no-check-gpg --arch armhf bullseye . http://mirrors.aliyun.com/debian/
   
8. 
   
9. # 如果要制作 ubuntu 根文件系统，则需要指定 ubuntu 的源
   
10. debootstrap --foreign --no-check-gpg --arch armhf jammy . https://mirrors.aliyun.com/ubuntu-ports/
    
11. 
    
12. cp /usr/bin/qemu-arm-static usr/bin/
    
13. LC_ALL=C LANGUAGE=C LANG=C chroot . /debootstrap/debootstrap --second-stage

boot.scr 生成过程：

• 这个文件有些参数需要根据 u-boot-sunxi-with-spl.bin 来修改，在此先行一步，将参数设置好，后续自行验证
• 创建 boot.cmd 文件并编辑
• 使用 mkimage 工具将 boot.cmd 转换为 boot.scr
  

1. # boot.cmd 内容如下
   
2. 
   
3. setenv bootargs console=ttyS0,115200 root=/dev/mmcblk0p2 rootwait panic=10
   
4. load mmc 0:1 0x43000000 sun7i-a20-cubieboard2.dtb || load mmc 0:1 0x43000000 boot/sun7i-a20-cubieboard2.dtb
   
5. load mmc 0:1 0x42000000 zImage || load mmc 0:1 0x42000000 boot/zImage
   
6. bootz 0x42000000 - 0x43000000

复制代码

1. # 将 boot.cmd 转换为 boot.scr
   
2. 
   
3. mkimage -C none -A arm -T script -d boot.cmd boot.scr
