一、简介

官方指导地址：SPI Flash系统编译
大佬指导博客（上）
大佬指导博客（下）
本文基本上都是在上面的资料下指导完成，但是还是踩了一些坑，故总结所有的细节，形成较为详细的步骤，指导萌新一次点亮成功

二、准备工作

硬件准备：

焊接好Nor Flash和引脚线接上串口Debug线，多留一根用于进入fel模式接上UART线，注意是T接R，R接T

软件准备：

u-boot源码Gitee仓库：分支v3s-spi-experimentallinux源码Gitee仓库：zero-4.10.y分支rootfs-brmin压缩包和交叉编译工具Gitee仓库烧写工具Gitee仓库

工具准备：

推荐一个Windows下的串口工具：mobaxterm

三、制作u-boot 1.修改uboot源码

下载uboot源码：

git clone -b v3s-spi-experimental https://gitee.com/cats_eat_big_fish/u-boot.git

在文件 include/configs/sun8i.h 中添加默认bootcmd和bootargs的环境变量设置，注意添加的位置在“ #include ”的前边。
源码：vim include/configs/sun8i.h

#ifndef __CONFIG_H
#define __CONFIG_H



#ifdef CONFIG_USB_EHCI
#define CONFIG_USB_EHCI_SUNXI
#endif

#ifdef CONFIG_MACH_SUN8I_H3
    #define CONFIG_SUNXI_USB_PHYS   4
#elif defined CONFIG_MACH_SUN8I_A83T
    #define CONFIG_SUNXI_USB_PHYS   3
#elif defined CONFIG_MACH_SUN8I_V3S
    #define CONFIG_SUNXI_USB_PHYS   1
#else
    #define CONFIG_SUNXI_USB_PHYS   2
#endif


#include 

#endif 

添加

#define CONFIG_BOOTCOMMAND   "sf probe 0; "                           
                             "sf read 0x41800000 0x100000 0x10000; "  
                             "sf read 0x41000000 0x110000 0x400000; " 
                             "bootz 0x41000000 - 0x41800000"

 #define CONFIG_BOOTARGS      "console=ttyS0,115200 earlyprintk panic=5 rootwait " 
                             "mtdparts=spi32766.0:1M(uboot)ro,64k(dtb)ro,4M(kernel)ro,-(rootfs) root=31:03 rw rootfstype=jffs2"

结果图

为了适配XT25F128B的Nor Flash，还需要修改文件：drivers/mtd/spi/spi_flash_ids.c

const struct spi_flash_info spi_flash_ids[] = {
    ...
    {"w25q128fw",      INFO(0xef6018, 0x0,  64 * 1024,   256, RD_FULL | WR_QPP | SECT_4K) },
    {"xt25f128b",      INFO(0x0b4018, 0x0,  64 * 1024,   256, RD_FULL | WR_QPP | SECT_4K) },
    ...
};

修改后的CONFIG_SPI_FLASH_WINBOND有一下这些

#ifdef CONFIG_SPI_FLASH_WINBOND     
    {"w25p80",     INFO(0xef2014, 0x0,  64 * 1024,    16, 0) },
    {"w25p16",     INFO(0xef2015, 0x0,  64 * 1024,    32, 0) },
    {"w25p32",     INFO(0xef2016, 0x0,  64 * 1024,    64, 0) },
    {"w25x40",     INFO(0xef3013, 0x0,  64 * 1024,     8, SECT_4K) },
    {"w25x16",     INFO(0xef3015, 0x0,  64 * 1024,    32, SECT_4K) },
    {"w25x32",     INFO(0xef3016, 0x0,  64 * 1024,    64, SECT_4K) },
    {"w25x64",     INFO(0xef3017, 0x0,  64 * 1024,   128, SECT_4K) },
    {"w25q80bl",       INFO(0xef4014, 0x0,  64 * 1024,    16, RD_FULL | WR_QPP | SECT_4K) },
    {"w25q16cl",       INFO(0xef4015, 0x0,  64 * 1024,    32, RD_FULL | WR_QPP | SECT_4K) },
    {"w25q32bv",       INFO(0xef4016, 0x0,  64 * 1024,    64, RD_FULL | WR_QPP | SECT_4K) },
    {"w25q64cv",       INFO(0xef4017, 0x0,  64 * 1024,   128, RD_FULL | WR_QPP | SECT_4K) },
    {"w25q128bv",      INFO(0xef4018, 0x0,  64 * 1024,   256, RD_FULL | WR_QPP | SECT_4K) },
    {"w25q256",    INFO(0xef4019, 0x0,  64 * 1024,   512, RD_FULL | WR_QPP | SECT_4K) },
    {"w25q80bw",       INFO(0xef5014, 0x0,  64 * 1024,    16, RD_FULL | WR_QPP | SECT_4K) },
    {"w25q16dw",       INFO(0xef6015, 0x0,  64 * 1024,    32, RD_FULL | WR_QPP | SECT_4K) },
    {"w25q32dw",       INFO(0xef6016, 0x0,  64 * 1024,    64, RD_FULL | WR_QPP | SECT_4K) },
    {"w25q64dw",       INFO(0xef6017, 0x0,  64 * 1024,   128, RD_FULL | WR_QPP | SECT_4K) },
    {"w25q128fw",      INFO(0xef6018, 0x0,  64 * 1024,   256, RD_FULL | WR_QPP | SECT_4K) },
    {"xt25f128b",      INFO(0x0b4018, 0x0,  64 * 1024,   256, RD_FULL | WR_QPP | SECT_4K) },
#endif

还需要添加设备树中关于Flash的声明，添加新增加的Flash型号，修改文件：arch/arm/dts/sun8i-v3s-licheepi-zero.dts
【注意】compatible中需要添加**“winbond, xt25f128b”**这一项

// 新添加的关于FLash的声明
&spi0 {
	status = "okay";
	
	xt25f128b:xt25f128b@0 {
		compatible = "winbond, xt25f128b", "jedec,spi-nor";
		reg = <0x0>;
		spi-max-frequency = <50000000>;
		#address-cells = <1>;
		#size-cells = <1>;
	};
};

到此为止，uboot的源码修改就完成了

2.修改配置项

这边推荐就采用系统默认的配置项：
LicheePi_Zero_800x480LCD_defconfig
LicheePi_Zero480x272LCD_defconfig
LicheePi_Zero_defconfig
可以根据你的硬件需求选择，我这边是输入：
make ARCH=arm LicheePi_Zero_800x480LCD_defconfig
然后再确认下配置项是否有问题，输入：
make ARCH=arm menuconfig
确保以下几项配置与图片一致，如果不对就修改
1.Architecture select ：ARM architecture

2.Device Drivers > SPI Support

3.Device Drivers > SPI Flash Support

3.安装编译环境

按简介中的地址，下载交叉编译器：gcc-linaro-6.3.1-2017.05-x86_64_arm-linux-gnueabihf 下载链接

git clone https://gitee.com/cats_eat_big_fish/rootfs-brmin.git

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
# add: PATH="$PATH:/opt/gcc-linaro-6.3.1-2017.05-x86_64_arm-linux-gnueabihf/bin"
source /etc/bash.bashrc
arm-linux-gnueabihf-gcc -v

安装dtc编译器

4.编译uboot

编译指令：
time make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- 2>&1 | tee build.log
如果没有设置交叉便器的环境变量，也可以直接传交叉编译器的绝对路径：
time make ARCH=arm CROSS_COMPILE={YourCrossToolPath}/arm-linux-gnueabihf- 2>&1 | tee build.log
编译成功后会在目录下生成文件：
u-boot-sunxi-with-spl.bin

四、制作内核 1.修改linux源码

下载linux内核源码，由于分支众多，下载全部仓库非常的大，推荐只下载目标分支：

git clone -b zero-4.10.y https://gitee.com/cats_eat_big_fish/linux.git

修改dts配置添加SPI Flash节点，和uboot类似操作
文件路径：arch/arm/boot/dts/sun8i-v3s-licheepi-zero.dts

// 新添加的SPI Flash设备节点描述
&spi0 {
        status ="okay";

        xt25f128b:xt25f128b@0 {
                compatible = "winbond, xt25f128b", "jedec,spi-nor";
                reg = <0x0>;
                spi-max-frequency = <50000000>;
                #address-cells = <1>;
                #size-cells = <1>;
        };

};

添加对XT25F128B的设备支持
修改文件：drivers/mtd/spi-nor/spi-nor.c中的spi_nor_ids

{ "xt25f128b", INFO(0x0b4018, 0, 64 * 1024, 256, SPI_NOR_DUAL_READ | SPI_NOR_QUAD_READ) },

2.修改配置项

在linux的根目录底下运行默认配置选项设置

make ARCH=arm licheepi_zero_defconfig

然后再进行菜单选项设置

make ARCH=arm menuconfig

保证一下几项配置和图中一致，如果不是则修改为一致
1.Device Drivers ‣ Memory Technology Device (MTD) support ‣ Command line partition table parsing

2.File systems ‣ Miscellaneous filesystems ‣ Journalling Flash File System v2 (JFFS2) support

到此就完成了内核的修改和配置了

3.编译内核文件及设备树文件

编译内核文件：

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j16

编译设备树文件

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

编译成功会显示

  SHIPPED arch/arm/boot/compressed/fdt_ro.c
  SHIPPED arch/arm/boot/compressed/fdt_wip.c
  SHIPPED arch/arm/boot/compressed/fdt.c

  DTC     arch/arm/boot/dts/sun8i-v3s-licheepi-zero.dtb
  DTC     arch/arm/boot/dts/sun8i-v3s-licheepi-zero-dock.dtb

生成的目标文件分别是：
arch/arm/boot/zImage
arch/arm/boot/dts/sun8i-v3s-licheepi-zero.dtb

五、制作文件系统镜像

我们还需要文件系统，找到之前连同编译工具一起git下来的文件系统压缩包
rootfs-brmin.tar.gz
将它解压，得到rootfs-brmin文件夹

tar xzvf rootfs-brmin.tar.gz

安装jfft2文件系统制作工具

sudo apt-get install mtd-utils

使用命令生成文件系统镜像

fakeroot mkfs.jffs2 -s 0x100 -e 0x10000 -p 0xAF0000 -d rootfs-brmin/ -o jffs2.img

具体为什么这么写可以参考简介中的链接，这里不做过多解释
【注意】前面一定要加fakeroot，否则会造成文件系统启动无权限的异常

然后我们就得到了一个jffs2.img的文件

-rw-r--r--  1 xjc xjc   3080192 Mar  8 18:36 jffs2.img

六、打包刷写 1.打包

到此步骤为止，我们一共获得了以下几个文件：

uboot文件：u-boot/u-boot-sunxi-with-spl.binlinux内核文件：linux/arch/arm/boot/zImagedts设备文件：linux/arch/arm/boot/dts/sun8i-v3s-licheepi-zero.dtb文件系统镜像文件：jffs2.img

这时候我们需要将所有文件打包成烧录文件
这里我直接提供一个烧录脚本

dd if=/dev/zero of=./out/flashimg.bin bs=1M count=16
dd if=./u-boot/u-boot-sunxi-with-spl.bin of=./out/flashimg.bin bs=1K conv=notrunc
dd if=./linux/arch/arm/boot/dts/sun8i-v3s-licheepi-zero.dtb of=./out/flashimg.bin bs=1K seek=1024 conv=notrunc
dd if=./linux/arch/arm/boot/zImage of=./out/flashimg.bin bs=1K seek=1088 conv=notrunc
dd if=jffs2.img of=./out/flashimg.bin bs=1K seek=5184 conv=notrunc

执行完过后就会在out里面生成我们的目标文件：flashimg.bin

其中showInfo.sh的脚本内容是查看硬件信息的：

sudo sunxi-fel version
sudo sunxi-fel spiflash-info

其中write.sh的脚本内容是刷写的：

sudo sunxi-fel -p spiflash-write 0 flashimg.bin

以上两个脚本都需要安装sunxi-fel工具
下载sunxi-fel工具

git clone -b spi-rebase https://gitee.com/cats_eat_big_fish/sunxi-tools.git

进入工具目录执行 make && sudo make install

xjc@ubuntu:~/sunxi-tools$ make && sudo make install
cc -std=c99 -Wall -Wextra -Wno-unused-result -D_POSIX_C_SOURCE=200112L -D_BSD_SOURCE -D_DEFAULT_SOURCE -Iinclude/  `pkg-config --cflags libusb-1.0`  -o sunxi-fel fel.c progress.c soc_info.c fel_lib.c fel-spiflash.c  `pkg-config --libs libusb-1.0`

ln -nsf sunxi-fexc bin2fex
ln -nsf sunxi-fexc fex2bin
install -d /usr/local/bin
+ install -m0755 sunxi-fexc /usr/local/bin/sunxi-fexc

+ ln -nfs sunxi-fexc /usr/local/bin/bin2fex
+ ln -nfs sunxi-fexc /usr/local/bin/fex2bin

如果出现：fel_lib.c:26:20: fatal error: libusb.h: No such file or directory，那需要安装libusb：

sudo apt-get install libusb-1.0-0-dev

2.刷写

进入USB下载模式：fel模式
上电时候将SPI_MISO拉低到地，运行showInfo.sh脚本

xjc@ubuntu:~/lichee/out$ ./showInfo.sh 
[sudo] password for xjc: 
AWUSBFEX soc=00001681(V3s) 00000001 ver=0001 44 08 scratchpad=00007e00 00000000 00000000
No SPI flash detected.

断开SPI_MISO的接地

xjc@ubuntu:~/lichee/out$ ./showInfo.sh 
AWUSBFEX soc=00001681(V3s) 00000001 ver=0001 44 08 scratchpad=00007e00 00000000 00000000
Manufacturer: Unknown (0Bh), model: 40h, size: 16777216 bytes.

这里是因为已经刷成功过了，所以能识别，空的可能不是这个样子

这时候可以执行write.sh

等待刷写完就好了，接上调试接口，重新上电，从调试接口就可以指导是否成功了，全部按上面步骤做且硬件一致的话，应该会成功；如果未成功，找找其他的大佬的文章排查问题吧！
