v3S编译大全（uboot 主线linux buildroot）
·
一、github代理下载
在我们编译的过程中需要去github中下载程序，但是速度非常慢，这里我们就可以用一个代理去下载，速度会稍微快一点。
可以将本来的
git clone https://github.com/xxx.git
改成：
git clone https://github.com.cnpmjs.org/xxx.git
这样通过代理可以比较轻松地加速。
二、Uboot
1.uboot下载
//普通
git clone https://github.com.cnpmjs.org/Lichee-Pi/u-boot.git -b v3s-current
//支持spi flash
git clone https://github.com.cnpmjs.org/Lichee-Pi/u-boot.git -b v3s-spi-experimental
这里我们使用的是普通版本。
下载过程可能有点慢，大家稍微等一下
上述就是下载完成，下载完成后会在当前目录生成u-boot
2.uboot的基本结构
├── api 存放uboot提供的API接口函数
├── arch 平台相关的部分我们只需要关心这个目录下的ARM文件夹
│ ├──arm
│ │ └──cpu
│ │ │ └──armv7
│ │ └──dts
│ │ │ └──*.dts 存放设备的dts,也就是设备配置相关的引脚信息
├── board 对于不同的平台的开发板对应的代码
├── cmd 顾名思义，大部分的命令的实现都在这个文件夹下面。
├── common 公共的代码
├── configs 各个板子的对应的配置文件都在里面，我们的Lichee配置也在里面
├── disk 对磁盘的一些操作都在这个文件夹里面，例如分区等。
├── doc 参考文档，这里面有很多跟平台等相关的使用文档。
├── drivers 各式各样的驱动文件都在这里面
├── dts 一种树形结构（device tree）这个应该是uboot新的语法
├── examples 官方给出的一些样例程序
├── fs 文件系统，uboot会用到的一些文件系统
├── include 头文件，所有的头文件都在这个文件夹下面
├── lib 一些常用的库文件在这个文件夹下面
├── Licenses 这个其实跟编译无关了，就是一些license的声明
├── net 网络相关的，需要用的小型网络协议栈
├── post 上电自检程序
├── scripts 编译脚本和Makefile文件
├── spl second program loader，即相当于二级uboot启动。
├── test 小型的单元测试程序。
└── tools 里面有很多uboot常用的工具。
3.uboot配置屏幕
//不同屏幕不同配置（配置文件在configs文件夹下）--------------------------------------
//默认
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- LicheePi_Zero_defconfig
//4.3寸屏
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- LicheePi_Zero_480x272LCD_defconfig
//5寸屏
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- LicheePi_Zero_800x480LCD_defconfig
这里我们使用的是5寸屏幕
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- LicheePi_Zero_800x480LCD_defconfig
4.修改可以从tf卡启动
如果不修改这个，后面添加的内核和文件系统都不能启动，但是uboot可以启动（这个真是血的教训）
修改 include/configs/sun8i.h, 使u-boot可以直接从tf卡启动：
vim include/configs/sun8i.h
#define CONFIG_BOOTCOMMAND "setenv bootm_boot_mode sec; " \
"load mmc 0:1 0x41000000 zImage; " \
"load mmc 0:1 0x41800000 sun8i-v3s-licheepi-zero-dock.dtb; " \
"bootz 0x41000000 - 0x41800000;"
#define CONFIG_BOOTARGS "console=ttyS0,115200 panic=5 rootwait root=/dev/mmcblk0p2 earlyprintk rw vt.global_cursor_default=0"
5.配置
这一步我们暂时先不用配置
make ARCH=arm menuconfig
6.编译
ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make -j4
生成的uboot就在这个目录下面
6.烧录测试
1.进入 fel 模式使用 sunxi-fel 工具烧录
关于这个工具的安装，请看连接：暂时还没有写
1.基本命令
//检查是否可以探测到芯片信息：
sudo sunxi-fel -l
//确认是否成功进入fel模式：
sudo sunxi-fel ver
2.有两种方式进行程序下载：
烧录到RAM中去执行，以 uboot file-with-spl形式进行（单次运行，测试时个人推荐（需要先用上面的指令测试连接成功）
sudo sunxi-fel uboot u-boot-sunxi-with-spl.bin
烧录到 spi-flash （开机自启）
sunxi-fel -p spiflash-write 0 u-boot-sunxi-with-spl.bin
注意：如果烧录到 spi-flash ，需要修改 include/configs/sun8i.h ，从flash引导系统
2.烧录到TF/SD卡
TF卡中的系统镜像一般分为三个区：
boot区或者引导区 - 该部分没有文件系统而是直接将二进制的bootloader(uboot)文件直接写入。
linux内核区 - fat文件系统，存放linux内核、内核参数文件还有设备数dtb文件。
rootfs分区 - 用来存放根文件系统和用户数据等，一般是ext4文件分区格式
ls /dev/sd*
//删除TF/SD的分区信息
sudo dd if=/dev/zero of=/dev/sdb bs=512K count=1
//烧录到TF卡（u-boot-sunxi-with-spl.bin在uboot根目录下）
sudo dd if=u-boot-sunxi-with-spl.bin of=/dev/sdb bs=1024 seek=8

三、主线linxu编译与烧录
1.下载
# 默认是zero-4.10.y分支：
git clone https://github.com/Lichee-Pi/linux.git
# 或者`zero-4.13.y`对网卡的支持更好
git clone -b zero-4.13.y https://github.com/Lichee-Pi/linux.git
# 或者使用最新的内核：
git clone -b zero-5.2.y https://github.com/Lichee-Pi/linux.git
这里使用zero-4.10.y`
下载很慢
解压
2.修改顶层Makefile
在内核根目录下的Makefile364行修改默认编译器，可以直接用make编译：
# ARCH ?= $(SUBARCH)
ARCH ?= arm
CROSS_COMPILE ?= arm-linux-gnueabihf-
修改后
3.编译
1.不修改Makefile
make ARCH=arm licheepi_zero_defconfig
make ARCH=arm menuconfig #add bluethooth, etc.
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j16
大概十分钟
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j16 INSTALL_MOD_PATH=out modules
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j16 INSTALL_MOD_PATH=out modules_install
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- dtbs
2.修改Makefile
sudo make licheepi_zero_defconfig
sudo make menuconfig #add bluethooth, etc
sudo make -j16
如果不行，使用
sudo make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j16
还是不行的话。先用sudo -i获取root权限
再执行
编译时间15:02-15:12大概十分钟
make -j16 INSTALL_MOD_PATH=out modules
make -j16 INSTALL_MOD_PATH=out modules_install
make dtbs
4.编译之后生成文件
编译完成后，zImage在arch/arm/boot/下，驱动模块在out/下。
设备树文件在arch/arm/boot/dts/下。
普通板的设备树：sun8i-v3s-licheepi-zero.dtb
dock板的设备树：sun8i-v3s-licheepi-zero-dock.dtb
LCD_480x272的设备树：sun8i-v3s-licheepi-zero-with-480x272-lcd.dtb
LCD_800x480的设备树：sun8i-v3s-licheepi-zero-with-800x480-lcd.dtb
这里提醒一下，zero-4.10.y的不生成后面两个dtb文件
最新的zero-5.2.y这几个文件都生成。
四、Buildroot
1.下载
wget https://buildroot.org/downloads/buildroot-2019.08.tar.gz
解压
tar xvf buildroot-2019.08.tar.gz&&cd buildroot-2019.08/
2.配置
make menuconfig
需要配置下面两个地方
配置下面那个配置需要先查看编译工具链的信息。
查询编译工具链所在位置：
which arm-linux-gnueabihf-gcc
读取编译工具链里的内核版本：
编译工具链内核头文件是
cat /usr/local/arm/gcc-linaro-6.3.1-2017.02-x86_64_arm-linux-gnueabihf/arm-linux-gnueabihf/libc/usr/include/linux/version.h
可以从中读取内核版本。
263680的二进制为0x40600，则对应的内核版本号为4.6.0。
根据上面获取的编译工具的信息可知我们应该配置为
/usr/local/arm/gcc-linaro-6.3.1-2017.02-x86_64_arm-linux-gnueabihf/
$(ARCH)-linux-gnueabihf
6.3.x
4.6.x
还可以设置主机名，root密码，配置自己需要的软件包等，后续再更新。
3.编译
make
如果编译不成功
要先sudo make clean
再sudo make
编译需要好久好久，请慢慢等待。
17:00-17:34大概半个小时左右
4.生成的文件
编译完成后，生成的根文件系统在 output/images/rootfs.tar。
五、GParted分区工具
这里介绍一个分区工具，分区时间有点慢（不知道是不是我操作有问题）
在Ububtu software下载
下载这个工具
分区
卸载并且删除所有分区
分配两个分区
大概时间20:48-22:36
六、烧录全部流程
0.准备阶段
为了后续的操作方便，我们可以新建一个文件夹，把所有需要的东西都拷贝到一个文件夹
mkdir img
1.拷贝uboot
cp u-boot/u-boot-sunxi-with-spl.bin img/
2.拷贝zImage和dtb
cp linux/arch/arm/boot/zImage img/
cp linux/arch/arm/boot/dts/sun8i-v3s-licheepi-zero* img/
3.rootfs
cp buildroot-2019.08/output/images/rootfs.tar img/
4.img文件夹
查看img目录
5.查看挂载tf卡
df -lh
1.烧录uboot
sudo dd if=u-boot-sunxi-with-spl.bin of=/dev/sdb bs=1024 seek=8
2.烧录zImage和dtb
直接拷贝kernel 设备树拷贝到BOOT也就是/media/luatao/BOOT
cp sun8i-v3s-licheepi-zero* /media/luatao/BOOT
cp zImage /media/luatao/BOOT
3.烧录rootfs
解压文件系统到/media/luatao/rootfs
tar vxf rootfs.tar -C/media/luatao/rootfs
弹出SD卡
4.查看启动信息
