全志V3S环境编译开发流程

这里使用的是荔枝派Zero（官网上面没有带spiflash的）
首先准备一张SD卡

U-BOOT

首先需要配置交叉编译环境，这里就不多说了。需要的话前往Sipeed官网。
Sipeed

首先获取uboot源码

git clone https://github.com/Lichee-Pi/u-boot.git -b v3s-current
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- LicheePi_Zero_800x480LCD_defconfig
make ARCH=arm menuconfig
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-  -j16

根据自己的屏幕去选择配置文件 我这里是5寸RGB屏幕
选择了 LicheePi_Zero_800x480LCD_defconfig
另外还有
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- LicheePi_Zero480x272LCD_defconfig
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- LicheePi_Zero_defconfig

最后生成了bin文件

到此为止 U-BOOT准备完成了

下面开始编译Linux

Linux

首先获取Linux源码

git clone -b zero-5.2.y --depth 1 https://github.com/Lichee-Pi/linux.git

make licheepi_zero_defconfig
make menuconfig
make -j16
make -j16 INSTALL_MOD_PATH=out modules
make -j16 INSTALL_MOD_PATH=out modules_install
make dtbs

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/

我使用的事5寸屏幕
使用使用的设备树文件是
sun8i-v3s-licheepi-zero-with-800x480-lcd.dtb

buildroot

下面开始编译buildroot-
首先获取buildroot源码

wget https://buildroot.org/downloads/buildroot-2021.02.4.tar.gz

然后解压
、
配置

make menuconfig

修改如下图所示

设置编译链

接着要查看编译器的版本

cat version.h 

263680的二进制为0x40A03，则对应的内核版本号为4.10.3。
然后我们选择这个版本

同时这几个也勾上

还可以设置主机名，root密码，配置自己需要的软件包等

下面开始编译

make

如果编译失败请检查交叉编译器的路径然后出现编译
或者尝试make clean后再重新编译
在这个过程中比较漫长 因为需要下载一些软件包，慢慢等待吧！！！

到此为止
U-BOOT Linux 文件系统都准备好了 下面开始烧录

在烧录之前我们需要准备一张SD卡
然后下载一个工具

GParted分区工具

这个软件去Ubuntu应用商店直接下载即可
打开软件后把右上角切换成当前的SD卡 注意 这里千万别搞错了

然后卸载掉当前的分区

然后删除分区

然后添加分区


然后再添加一个ext4分区 如下图所示

然后如下图所示 点√进行保存操作然后完成分区

下面开始烧写U-Boot

然后查看SD卡看到了有3个分区

下面开始烧录uboot

sudo dd if=u-boot-sunxi-with-spl.bin of=/dev/sdb bs=1024 seek=8

要注意bin文件的路径

Uboot 烧录完成
下面就是zImage和dtb了
把Linux编译好的zImage复制到BOOT分区

cp arch/arm/boot/zImage  /media/dwh/BOOT

把Linux编译好的dtb复制到BOOT分区
我这个是5寸800x480屏幕

cp arch/arm/boot/dts/sun8i-v3s-licheepi-zero-with-800x480-lcd.dtb  /media/dwh/BOOT

这时候 zImage 和 dtb就复制好了

下面开始复制rootfs

首先进入该目录
buildroot-2021.02.4/output/images
这里的rootfs文件

解压到 rootfs分区

sudo tar -xvf ./rootfs.tar -C /media/dwh/rootfs/

下面就全部搞定了

这个时把SD卡插上去就可以跑起来了 但是 进入文件系统后串口可能无法使用 这时候我们还需要在文件系统的

cd etc/ inittab 
sudo vim inittab 

打开后加入

ttyS0::respawn:/sbin/getty -L ttyS0 115200 vt100 

保存退出！！！

下面把卡插入板子

然后使用一个CH340串口调试工具连接板子的uart0
打开xshell

可以看到U-BOOT已经启动了
这时候我们需要设置一下启动参数

setenv bootcmd 'load mmc 0:1 0x41000000 zImage;load mmc 0:1 0x41800000 sun8i-v3s-licheepi-zero-with-800x480-lcd.dtb;bootz 0x41000000 - 0x41800000;'
setenv bootargs console=ttyS0,115200 panic=5 console=tty0 rootwait root=/dev/mmcblk0p2 earlyprintk rw vt.global_cursor_default=0
saveenv

然后重启板子

最后成功进入文件系统
输入用户名 root

同时板子也成功显示

最后附上Log
