# SPI Flash 系统编译
在一些低成本应用场景，需要在SPI flash上启动系统，这需要对Uboot和系统镜像做些适配。
本文介绍SPI Flash镜像的制作过程。
## Flash分区规划
这里 使用MX25L25645G, 32M SPI flash作为启动介质，规划分区如下：
|分区序号|分区大小|分区作用|地址空间及分区名|
|--|--|--|--|
|mtd0|1MB|spl+uboot|0x0000000-0x0100000 : "uboot"|
|mtd1|64KB|dtb文件|0x0100000-0x0110000 : "dtb"|
|mtd2|4MB|linux内核|0x0110000-0x0510000 : "kernel"|
|mtd3|剩余|根文件系统|0x0510000-0x2000000 : "rootfs"|
## Uboot编译配置
由于目前Uboot环境变量固定存放在1MB位置之内，所有留给uboot的空间固定到flash前1MB的位置不变。
每个分区的大小必须是擦除块大小的整数倍，MX25L25645G的擦除块大小是64KB。
### 准备uboot
下载包含spi驱动的体验版本uboot，该驱动目前尚未合并到主线
`git clone -b v3s-spi-experimental https://github.com/Lichee-Pi/u-boot.git`
### 配置Flash支持型号
执行`make ARCH=arm menuconfig`打开uboot菜单配置，进入到`Device Drivers > SPI Flash Support`
注意看一下自己flash的厂家名称，例如选上Macronix SPI flash support用来支持测试用的flash：MX25L25645G。
如果使用的是16MB以上的flash，需要勾选flash bank支持选项，否则最多只能读到16MB：**CONFIG_SPI_FLASH_BAR**
### 配置uboot默认环境变量
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 <configs/sunxi-common.h>”的前边。
~~~
vi include/configs/sun8i.h
#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"
~~~
> 环境命令解析：
> sf probe 0; //初始化Flash设备（CS拉低）
> sf read 0x41800000 0x100000 0x10000; //从flash0x100000（1MB）位置读取dtb放到内存0x41800000偏移处。 //如果是bsp的bin，则是0x41d00000
sf read 0x41000000 0x110000 0x400000; //从flash0x110000（1MB+64KB）位置读取dtb放到内存0x41000000偏移处。
bootz 0x41000000 （内核地址）- 0x41800000（dtb地址） 启动内核
> 启动参数解析
> console=ttyS0,115200 earlyprintk panic=5 rootwait //在串口0上输出信息
> mtdparts=spi32766.0:1M(uboot)ro,64k(dtb)ro,4M(kernel)ro,-(rootfs) root=31:03 rw rootfstype=jffs2 //spi32766.0是设备名，后面是分区大小，名字，读写属性。
> root=31:03表示根文件系统是mtd3；jffs2格式
### 编译uboot
`time make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- 2>&1 | tee build.log`
会在目录下生成 u-boot-sunxi-with-spl.bin
## linux内核编译配置
linux内核基于github上的版本https://github.com/Lichee-Pi/linux.git，分支为最新的zero-4.13.y
### 内核选项配置
执行`make ARCH=arm menuconfig`打开内核菜单配置，
进入到`Device Drivers > Memory Technology Device (MTD) support`，
确保选择上mtd的`<*> Command line partition table parsing`支持，该项目用来解析uboot传递过来的flash分区信息。
以及SPI-NOR 设备的支持。
添加对jffs2文件系统的支持，路径在`File systems > Miscellaneous filesystems-> Journalling Flash File System v2 (JFFS2) support`
### 设备树配置
修改dts配置添加spi flash节点
` vi arch/arm/boot/dts/sun8i-v3s-licheepi-zero.dts`
添加spi节点配置:
~~~
&spi0 {
status ="okay";
mx25l25635e:mx25l25635e@0 {
compatible = "jedec,spi-nor";
reg = <0x0>;
spi-max-frequency = <50000000>;
#address-cells = <1>;
#size-cells = <1>;
};
};
~~~
这里的flash型号需要在下表之中，否则将无法识别：
（注意容量也一定要对应）
~~~

* hack around the fact that the SPI core does not provide uevent

{ },
};
~~~
退出菜单配置并编译内核和dts
~~~
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j32
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- dtbs
~~~
## 准备镜像文件
### 下载根文件系统
首先选择rootfs文件系统，我是用的是群朋提供的最小根文件系统rootfs-brmin.tar.gz，大小只有3M左右，下载地址在
~~~
https://pan.baidu.com/share/link?
shareid=1432204556&uk=3658413294#list/path=%2F
Lichee Zero>zero_imager.zip
~~~
### 制作jffs2文件系统
Flash支持jffs2文件系统格式，所以需要使用此该rootfs制作jffs2文件系统镜像、
下载jffs2文件系统制作工具
`apt-get install mtd-utils`
解压 rootfs-brmin.tar.gz
`tar xzvf rootfs-brmin.tar.gz`
计算好jffs的大小，可以使用zero_imager里的make_jffs2.sh 32生成
总空间是32M-1M-64K-4M=0x1AF0000
`mkfs.jffs2 -s 0x100 -e 0x10000 -p 0x1AF0000 -d rootfs/ -o jffs2.img`
页大小0x100 256字节
块大小0x10000 64k
jffs2分区总空间0x1AF0000
jffs2.img是生成的文件系统镜像。
最后将uboot，dtb，kernel，rootfs打包成一个系统镜像，命令如下；
（即zero_imager里的make_spiflash.sh 32 dock）
~~~
#!/bin/sh
dd if=/dev/zero of=flashimg.bin bs=1M count=$1
dd if=u-boot-sunxi-with-spl-$2.bin of=flashimg.bin bs=1K conv=notrunc
dd if=sun8i-v3s-licheepi-zero-$2.dtb of=flashimg.bin bs=1K seek=1024 conv=notrunc
dd if=zImage of=flashimg.bin bs=1K seek=1088 conv=notrunc
dd if=jffs2.img of=flashimg.bin bs=1K seek=5184 conv=notrunc
~~~
第一步：生成一个空文件，大小是32MB
第二步：将uboot添加到文件开头
第三步：将dtb放到1M偏移处
第四步：将kernel放到1M+64K偏移处
第五步：将rootfs放到1M+64K+4M偏移处
偏移大小是seek，单位是KB。
执行完毕后生成镜像文件flashimg.bin
## 烧写镜像
### 下载sunxiflash烧写工具
`git clone -b spi-rebase https://github.com/Icenowy/sunxi-tools.git`
注意是spi-rebase分支。
进入工具目录执行make && sudo make install
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`
### 进入fel模式
Zero有一个usb下载模式称为fel模式，进入fel模式有下面几种方式：
1. TF卡和spi flash 同时没有可启动镜像
也就是说你不插卡，且焊接的是新的或者没有有效镜像的spi flash，那就上电自动进入fel下载模式
2. TF卡中有进入fel模式的特殊固件 fel-sdboot.sunxi
如果你的spiflash已经有了启动镜像，那么需要在TF卡中烧入一个sunxi提供的启动工具
（dd if=fel-sdboot.sunxi of=/dev/mmcblk0 bs=1024 seek=8），
那么插入该TF卡启动会进入fel模式；
3. 上电时SPI_MISO拉低到地
该引脚为boot引脚，上电时出于低电平即会进入fel下载模式。
### sunxi-fel的操作
进入fel模式后使用usb数据线连接pc和zero,即可进行操作。
~~~
sudo sunxi-fel version #查看连接的cpu信息
AWUSBFEX soc=00001681(V3s) 00000001 ver=0001 44 08 scratchpad=00007e00 00000000 00000000
sudo sunxi-fel spiflash-info #显示flash信息
Manufacturer: Unknown (C2h), model: 20h, size: 33554432 bytes.
~~~
执行如下命令烧入我们前边制作好的镜像文件
~~~
sudo sunxi-fel -p spiflash-write 0 flashimg.bin
# -p 显示进度条
# spiflash-info Retrieves basic information
# spiflash-hex[dump] addr length Dumps SPI flash region in hex
# spiflash-read addr length file Write SPI flash contents into file
# spiflash-write addr file Store file contents into SPI flash
~~~
SPI flash下载速度约50KB/s，等待5分钟（16MB）或者10分钟（32MB），烧写完成，如果一切顺利，重新上电zero那么就会进入linux系统了，账号是root没有密码。

sunxi-fel v1.4.1-87-g78a7566
Usage: sunxi-fel [options] command arguments... [command...]
-h, --help Print this usage summary and exit
-v, --verbose Verbose logging
-p, --progress "write" transfers show a progress bar
-l, --list Enumerate all (USB) FEL devices and exit
-d, --dev bus:devnum Use specific USB bus and device number
--sid SID Select device by SID key (exact match)
spl file Load and execute U-Boot SPL
If file additionally contains a main U-Boot binary
(u-boot-sunxi-with-spl.bin), this command also transfers that
to memory (default address from image), but won't execute it.
uboot file-with-spl like "spl", but actually starts U-Boot
U-Boot execution will take place when the fel utility exits.
This allows combining "uboot" with further "write" commands
(to transfer other files needed for the boot).
hex[dump] address length Dumps memory region in hex
dump address length Binary memory dump
exe[cute] address Call function address
reset64 address RMR request for AArch64 warm boot
memmove dest source size Copy <size> bytes within device memory
readl address Read 32-bit value from device memory
writel address value Write 32-bit value to device memory
read address length file Write memory contents into file
write address file Store file contents into memory
write-with-progress addr file "write" with progress bar
write-with-gauge addr file Output progress for "dialog --gauge"
write-with-xgauge addr file Extended gauge output (updates prompt)
multi[write] # addr file ... "write-with-progress" multiple files,
sharing a common progress status
multi[write]-with-gauge ... like their "write-with-*" counterpart,
multi[write]-with-xgauge ... but following the 'multi' syntax:
<#> addr file [addr file [...]]
echo-gauge "some text" Update prompt/caption for gauge output
ver[sion] Show BROM version
sid Retrieve and output 128-bit SID key
clear address length Clear memory
fill address length value Fill memory
spiflash-info Retrieves basic information
spiflash-hex[dump] addr length Dumps SPI flash region in hex
spiflash-read addr length file Write SPI flash contents into file
spiflash-write addr file Store file contents into SPI flash
