# 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。 ![](https://box.kancloud.cn/b4cce3d6f353a3aabb326dab402d58a3_1642x622.jpg) ~~~ 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。 ![](https://box.kancloud.cn/3ed4fd5d601aceb7f896521ba4c67cf6_1430x862.jpg) 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` ![](https://box.kancloud.cn/3be64c60667c0aa3a906f095171d1fda_1396x746.png) ### 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>; }; }; ~~~ ![](https://box.kancloud.cn/611c8c327abb212991c3d0c02b0cf6d8_954x809.jpg) 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) ~~~ 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 */ {"spi-nor"}, /* * Entries not used in DTs that should be safe to drop after replacing * them with "spi-nor" in platform data. */ {"s25sl064a"}, {"w25x16"}, {"m25p10"}, {"m25px64"}, /* * Entries that were used in DTs without "jedec,spi-nor" fallback and * should be kept for backward compatibility. */ {"at25df321a"}, {"at25df641"}, {"at26df081a"}, {"mx25l4005a"}, {"mx25l1606e"}, {"mx25l6405d"}, {"mx25l12805d"}, {"mx25l25635e"},{"mx66l51235l"}, {"n25q064"}, {"n25q128a11"}, {"n25q128a13"}, {"n25q512a"}, {"s25fl256s1"}, {"s25fl512s"}, {"s25sl12801"}, {"s25fl008k"}, {"s25fl064k"}, {"sst25vf040b"},{"sst25vf016b"},{"sst25vf032b"},{"sst25wf040"}, {"m25p40"}, {"m25p80"}, {"m25p16"}, {"m25p32"}, {"m25p64"}, {"m25p128"}, {"w25x80"}, {"w25x32"}, {"w25q32"}, {"w25q32dw"}, {"w25q80bl"}, {"w25q128"}, {"w25q256"}, /* Flashes that can't be detected using JEDEC */ {"m25p05-nonjedec"}, {"m25p10-nonjedec"}, {"m25p20-nonjedec"}, {"m25p40-nonjedec"}, {"m25p80-nonjedec"}, {"m25p16-nonjedec"}, {"m25p32-nonjedec"}, {"m25p64-nonjedec"}, {"m25p128-nonjedec"}, /* Everspin MRAMs (non-JEDEC) */ { "mr25h256" }, /* 256 Kib, 40 MHz */ { "mr25h10" }, /* 1 Mib, 40 MHz */ { "mr25h40" }, /* 4 Mib, 40 MHz */ { }, }; ~~~ 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 ~~~ ![](https://box.kancloud.cn/30a15ac70a49ffa8e966700b72d91478_1088x83.jpg) 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。 ![](https://box.kancloud.cn/94cba1c9e4539c2e54836d28a8bbe12b_1281x1002.jpg) ## 附录: 启动日志 ~~~ U-Boot SPL 2017.01-rc2-00073-gdd6e874-dirty (Oct 14 2017 - 16:33:01) DRAM: 64 MiB Trying to boot from sunxi SPI U-Boot 2017.01-rc2-00073-gdd6e874-dirty (Oct 14 2017 - 16:33:01 +0000) Allwinner Technology CPU: Allwinner V3s (SUN8I 1681) Model: Lichee Pi Zero DRAM: 64 MiB MMC: SUNXI SD/MMC: 0 SF: Detected mx25l25635f with page size 256 Bytes, erase size 64 KiB, total 32 MiB *** Warning - bad CRC, using default environment Setting up a 800x480 lcd console (overscan 0x0) dotclock: 33000kHz = 33000kHz: (1 * 3MHz * 66) / 6 In: serial@01c28000 Out: serial@01c28000 Err: serial@01c28000 U-Boot 2017.01-rc2-00073-gdd6e874-dirty (Oct 14 2017 - 16:33:01 +0000) Allwinner Technology CPU: Allwinner V3s (SUN8I 1681) Model: Lichee Pi Zero DRAM: 64 MiB MMC: SUNXI SD/MMC: 0 SF: Detected mx25l25635f with page size 256 Bytes, erase size 64 KiB, total 32 MiB *** Warning - bad CRC, using default environment Setting up a 800x480 lcd console (overscan 0x0) dotclock: 33000kHz = 33000kHz: (1 * 3MHz * 66) / 6 In: serial@01c28000 Out: serial@01c28000 Err: serial@01c28000 Net: No ethernet found. starting USB...
