lichee linux nfs,SPI Flash 系统编译
在一些低成本應(yīng)用場景，需要在SPI flash上啟動系統(tǒng)，這需要對Uboot和系統(tǒng)鏡像做些適配。
本文介紹SPI Flash鏡像的制作過程。
這里 使用 MX25L25645G, 32M SPI flash 作為啟動介質(zhì)，規(guī)劃分區(qū)如下：
分區(qū)序號
分區(qū)大小
分區(qū)作用
地址空間及分區(qū)名
mtd0
1MB
spl+uboot
0x0000000-0x0100000 : “uboot”
mtd1
64KB
dtb文件
0x0100000-0x0110000: “dtb”
mtd2
4MB
linux內(nèi)核
0x0110000-0x0510000 : “kernel”
mtd3
剩余
根文件系統(tǒng)
0x0510000-0x2000000 : “rootfs”
由于目前Uboot環(huán)境變量固定存放在1MB位置之內(nèi)，所有留給uboot的空間固定到flash前1MB的位置不變。
每個分區(qū)的大小必須是擦除塊大小的整數(shù)倍，MX25L25645G的擦除塊大小是64KB。
下載包含spi驅(qū)動的體驗版本uboot，該驅(qū)動目前尚未合并到主線
git clone -b v3s-spi-experimental https://github.com/Lichee-Pi/u-boot.git
執(zhí)行 make ARCH=arm menuconfig 打開uboot菜單配置，進(jìn)入到 Device Drivers ? SPI Flash Support
注意看一下自己flash的廠家名稱，例如選上Macronix SPI flash support用來支持測試用的flash：MX25L25645G。
如果使用的是16MB以上的flash，需要勾選flash bank支持選項，否則最多只能讀到16MB： CONFIG_SPI_FLASH_BAR
在文件 include/configs/sun8i.h 中添加默認(rèn)bootcmd和bootargs的環(huán)境變量設(shè)置，注意添加的位置在“ #include ”的前邊。
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"
環(huán)境命令解析：sf probe 0; //初始化Flash設(shè)備(CS拉低)
sf read 0x41800000 0x100000 0x10000; //從flash0x100000(1MB)位置讀取dtb放到內(nèi)存0x41800000偏移處。 //如果是bsp的bin，則是0x41d00000
sf read 0x41000000 0x110000 0x400000; //從flash0x110000(1MB+64KB)位置讀取dtb放到內(nèi)存0x41000000偏移處。
bootz 0x41000000 (內(nèi)核地址)- 0x41800000(dtb地址) 啟動內(nèi)核
啟動參數(shù)解析console=ttyS0,115200 earlyprintk panic=5 rootwait //在串口0上輸出信息
mtdparts=spi32766.0:1M(uboot)ro,64k(dtb)ro,4M(kernel)ro,-(rootfs) root=31:03 rw rootfstype=jffs2 //spi32766.0是設(shè)備名，后面是分區(qū)大小，名字，讀寫屬性。
root=31:03表示根文件系統(tǒng)是mtd3；jffs2格式
time make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- 2>&1 | tee build.log
會在目錄下生成 u-boot-sunxi-with-spl.bin
linux內(nèi)核基于github上的版本https://github.com/Lichee-Pi/linux.git，分支為最新的zero-4.13.y
執(zhí)行 make ARCH=arm menuconfig 打開內(nèi)核菜單配置，
進(jìn)入到 Device Drivers ? Memory Technology Device (MTD) support ，
確保選擇上mtd的 Command line partition table parsing 支持，該項目用來解析uboot傳遞過來的flash分區(qū)信息。
以及SPI-NOR 設(shè)備的支持。
添加對jffs2文件系統(tǒng)的支持，路徑在 File systems ? Miscellaneous filesystems ? Journalling Flash File System v2 (JFFS2) support
修改dts配置添加spi flash節(jié)點
vi arch/arm/boot/dts/sun8i-v3s-licheepi-zero.dts
添加spi節(jié)點配置:
&spi0 {
status ="okay";
mx25l25635e:mx25l25635e@0 {
compatible = "jedec,spi-nor";
reg = <0x0>;
spi-max-frequency = <50000000>;
#address-cells = <1>;
#size-cells = <1>;
};
};
這里的flash型號需要在下表之中，否則將無法識別：(注意容量也一定要對應(yīng))
static const struct spi_device_id m25p_ids[] = {
/*
* Allow non-DT platform devices to bind to the "spi-nor" modalias, and
* hack around the fact that the SPI core does not provide uevent
* matching for .of_match_table

{ },
};
退出菜單配置并編譯內(nèi)核和dts?
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j32
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- dtbs
首先選擇rootfs文件系統(tǒng)，我是用的是群朋提供的最小根文件系統(tǒng) rootfs-brmin.tar.gz，大小只有3M左右，下載地址在
https://pan.baidu.com/share/link?
shareid=1432204556&uk=3658413294#list/path=%2F
Lichee Zero>zero_imager.zip
Flash支持jffs2文件系統(tǒng)格式，所以需要使用此該rootfs制作jffs2文件系統(tǒng)鏡像、
下載jffs2文件系統(tǒng)制作工具
apt-get install mtd-utils
解壓 rootfs-brmin.tar.gz
tar xzvf rootfs-brmin.tar.gz
計算好jffs的大小，可以使用zero_imager里的 make_jffs2.sh 32 生成
總空間是32M-1M-64K-4M=0x1AF0000
mkfs.jffs2 -s 0x100 -e 0x10000 -p 0x1AF0000 -d rootfs/ -o jffs2.img
頁大小0x100 256字節(jié)
塊大小0x10000 64k
jffs2分區(qū)總空間0x1AF0000
jffs2.img是生成的文件系統(tǒng)鏡像。
最后將uboot，dtb，kernel，rootfs打包成一個系統(tǒng)鏡像，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： 生成一個空文件，大小是32MB
第二步： 將uboot添加到文件開頭
第三步： 將dtb放到1M偏移處
第四步： 將kernel放到1M+64K偏移處
第五步： 將rootfs放到1M+64K+4M偏移處
偏移大小是seek，單位是KB。
執(zhí)行完畢后生成鏡像文件 flashimg.bin
git clone -b spi-rebase https://github.com/Icenowy/sunxi-tools.git
注解
注意是spi-rebase分支。
進(jìn)入工具目錄執(zhí)行 make && sudo make install
如果出現(xiàn)：fel_lib.c:26:20: fatal error: libusb.h: No such file or directory，那需要安裝libusb：
sudo apt-get install libusb-1.0-0-dev
Zero有一個usb下載模式稱為fel模式，進(jìn)入fel模式有下面幾種方式：
TF卡和spi flash 同時沒有可啟動鏡像;也就是說你不插卡，且焊接的是新的或者沒有有效鏡像的spi flash，那就上電自動進(jìn)入fel下載模式
TF卡中有進(jìn)入fel模式的特殊固件 fel-sdboot.sunxi如果你的spiflash已經(jīng)有了啟動鏡像，那么需要在TF卡中燒入一個sunxi提供的 啟動工具
( dd if=fel-sdboot.sunxi of=/dev/mmcblk0 bs=1024 seek=8 )，
那么插入該TF卡啟動會進(jìn)入fel模式；
上電時SPI_MISO拉低到地該引腳為boot引腳，上電時出于低電平即會進(jìn)入fel下載模式。
進(jìn)入fel模式后使用usb數(shù)據(jù)線連接pc和zero,即可進(jìn)行操作。
sudo sunxi-fel version #查看連接的cpu信息
AWUSBFEX soc=00001681(V3s) 00000001 ver=0001 44 08 scratchpad=00007e00 00000000 00000000
sudo sunxi-fel spiflash-info #顯示flash信息
Manufacturer: Unknown (C2h), model: 20h, size: 33554432 bytes.
執(zhí)行如下命令燒入我們前邊制作好的鏡像文件
sudo sunxi-fel -p spiflash-write 0 flashimg.bin
# -p 顯示進(jìn)度條
# 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下載速度約50KB/s，等待5分鐘(16MB)或者10分鐘(32MB)，燒寫完成，如果一切順利，重新上電zero那么就會進(jìn)入linux系統(tǒng)了，賬號是root沒有密碼。

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 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
