# LicheePiZero启动镜像

### 介绍
LicheePiZero启动镜像,包含uboot.bin,设备树（dtb），zImage和rootfs

### u-boot
获取u-boot源码  
```
git clone https://github.com/Lichee-Pi/u-boot.git -b v3s-current
```

修改 include/configs/sun8i.h, 使u-boot可以直接从tf卡启动  

```
#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"
```
编译
```
cd u-boot

ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make LicheePi_Zero_800x480LCD_defconfig (群主网店5寸屏)
ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make LicheePi_Zero_480x272LCD_defconfig (通用4.3寸屏)
ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make LicheePi_Zero_defconfig (默认)

ARCH=arm make menuconfig

ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make
```

### Linux内核
安装交叉编译器
```
wget https://releases.linaro.org/components/toolchain/binaries/latest/arm-linux-gnueabihf/gcc-linaro-6.3.1-2017.05-x86_64_arm-linux-gnueabihf.tar.xz
tar xvf gcc-linaro-6.3.1-2017.05-x86_64_arm-linux-gnueabihf.tar.xz
mv gcc-linaro-6.3.1-2017.05-x86_64_arm-linux-gnueabihf /opt/
vim /etc/bash.bashrc
# 添加: PATH="$PATH:/opt/gcc-linaro-6.3.1-2017.05-x86_64_arm-linux-gnueabihf/bin"
arm-linux-gnueabihf-gcc -v
```

下载编译linux源码
```
git clone https://github.com/Lichee-Pi/linux.git -b zero-4.14.y
cd linux
make ARCH=arm licheepi_zero_defconfig
make ARCH=arm menuconfig   #add bluethooth, etc.
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j16
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
```

### Debian
准备工作:  
```
sudo apt install qemu-user-static -y
sudo apt install debootstrap -y
sudo su
mkdir rootfs
```

debootstrap  
```
debootstrap --foreign --verbose --arch=armhf  stretch rootfs http://ftp2.cn.debian.org/debian
```

挂载
```
cd rootfs
   mount --bind /dev dev/
   mount --bind /sys sys/
   mount --bind /proc proc/
   mount --bind /dev/pts dev/pts/
   cd ..
```

```
cp /usr/bin/qemu-arm-static rootfs/usr/bin/
chmod +x rootfs/usr/bin/qemu-arm-static
```

解压   
```
LC_ALL=C LANGUAGE=C LANG=C chroot rootfs /debootstrap/debootstrap --second-stage --verbose
```

在rootfs/lib文件夹下放入r8723bs.ko文件  
在rootfs/lib/firmware/rtlwifi文件夹(新建一个)下放入rtl8723bs_nic.bin文件  

安装东西
```
LC_ALL=C LANGUAGE=C LANG=C chroot rootfs

apt install net-tools
apt install udhcpc
sudo apt-get install wpasupplicant
```
```
passwd    #设置root密码
exit
rm rootfs/usr/bin/qemu-arm-static
umount dev/pts/
umount dev/
umount proc/
umount sys/
```
在rootfs下面 运行`tar cvzf ../debian9.9.rootfs.gz .`可以生成包  
解压到文件系统`sudo tar -xzvf debian9.9.rootfs.gz`

### 烧录
使用Gparted对SD卡进行分区  
进入软件后先在右上角选择SD卡，进入后默认是Ubuntu系统的分区。  
![choose sd](https://gitee.com/sin_-team/lichee-pi-zero-start-image/raw/master/images/choose_sd.png)  
卸载并删除SD卡所有分区，并新建两个分区  

建立第一个分区，大小32M，格式fat16，命名kernel  
![choose sd](https://gitee.com/sin_-team/lichee-pi-zero-start-image/raw/master/images/partition1.png)  

建立第二个分区，用尽剩余空间，格式ext4，命名rootfs  
![choose sd](https://gitee.com/sin_-team/lichee-pi-zero-start-image/raw/master/images/partition2.png)  

建好后如下  
![choose sd](https://gitee.com/sin_-team/lichee-pi-zero-start-image/raw/master/images/finish.png)  

`sudo fdisk -l`查看设备  
![choose sd](https://gitee.com/sin_-team/lichee-pi-zero-start-image/raw/master/images/dev.png)  


将uboot写入到SD卡8k偏移处(必须8K偏移)   

    cd ./u-boot
    sudo dd if=u-boot-sunxi-with-spl.bin of=/dev/sdb bs=1024 seek=8  #先确认盘符是否为sdb

复制kernel和根文件系统
把zImage, sun8i-v3s-licheepi-zero-dock.dtb拷贝到第一个分区

    cp linux/arch/arm/boot/zImage /media/bk/KERNAL
    cp linux/arch/arm/boot/dts/sun8i-v3s-licheepi-zero-dock.dtb /media/bk/KERNAL
注意：一定要用cp指令进行拷贝，千万别图省事就直接在桌面系统下直接进行复制粘贴操作。

把根文件系统解压到第二个分区  

    sudo tar -xzvf debian9.9.rootfs.gz -C /media/bk/rootfs
