HamsterBear 构建可启动的镜像

Allwinner SoC 上电后会执行BootROM中的程序，会依次从SDIO，SPI等接口查询可引导的设备，
SPI设备具有最低引导权，若无法查询到可引导设备，会自动进入FEL模式，此时可使用sunxi-fel
通过USB启动spl或者uboot，也可以将引导文件烧写进外部flash。

提供两种启动方式

• Nor Flash - XT25F128B等
• eMMC/MMC TF - SDIN5D2-4G TF等

两种启动方式的配置互相冲突

从Nor Flash启动 uboot 添加 flash id

其他id的flash的添加操作类似
vim drivers/mtd/spi/spi_flash_ids.c +154

vim u-boot/include/configs/suniv.h
添加

#define CONFIG_BOOTCOMMAND "sf probe 0 50000000; " \ "sf read 0x80C00000 0x100000 0x4000; " \ "sf read 0x80008000 0x110000 0x400000; " \ "bootz 0x80008000 - 0x80C00000" uboot 修改 bootargs

# uboot中使用了一块内存作为了LCD framebuffer，如果不限制内核内存空间，会导致lcd花屏一段时间 # mem=31M 是最简单的处理办法 make menuconfig 勾选Enable boot arguments 在Boot arguments后的括号中粘贴如下内容 console=tty0 console=ttyS0,115200 panic=5 root=/dev/mtdblock3 rw rootfstype=jffs2 mem=31M 修改linux dts

修改spi0节点

&spi0 { pinctrl-names = "default"; pinctrl-0 = <&spi0_pins_a>; status = "okay"; spi-max-frequency = <50000000>; flash: xt25f128@0 { #address-cells = <1>; #size-cells = <1>; compatible = "winbond,xt25f128", "jedec,spi-nor"; reg = <0>; spi-max-frequency = <50000000>; partitions { compatible = "fixed-partitions"; #address-cells = <1>; #size-cells = <1>; partition@0 { label = "u-boot"; reg = <0x000000 0x100000>; read-only; }; partition@100000 { label = "dtb"; reg = <0x100000 0x10000>; read-only; }; partition@110000 { label = "kernel"; reg = <0x110000 0x400000>; read-only; }; partition@510000 { label = "rootfs"; reg = <0x510000 0xAF0000>; }; }; }; }; 自定义根文件系统

# 解包根文件系统 tar zxvf rootfs.tar.gz -C rootfs/ # 拷贝需要的文件 cp demo rootfs/root/ cp lib/module/5.19-model/ rootfs/lib/module/ -r # 重新打包 mkfs.jffs2 -L -s 0x100 -e 0x10000 --pad=0xAF0000 -d rootfs/ -o rootfs.jffs2 创建大小为16M的空文件

dd if=/dev/zero of=nor_flash_image bs=1M count=16 将对应文件写入启动文件 或者 flash

# 写入文件 dd if=u-boot-sunxi-with-spl.bin of=nor_flash_image bs=1K conv=notrunc dd if=suniv-f1c100s-licheepi-nano-with-lcd.dtb of=nor_flash_image bs=1K seek=1024 conv=notrunc dd if=zImage of=nor_flash_image bs=1K seek=1088 conv=notrunc dd if=rootfs.jffs2 of=nor_flash_image bs=1K seek=5184 conv=notrunc # 直接写入flash sudo sunxi-fel -p spiflash-write 0x000000 u-boot-sunxi-with-spl.bin sudo sunxi-fel -p spiflash-write 0x100000 suniv-f1c100s-licheepi-nano-with-lcd.dtb sudo sunxi-fel -p spiflash-write 0x110000 zImage sudo sunxi-fel -p spiflash-write 0x510000 rootfs.jffs2 启动日志

从 MMC/eMMC TF 启动 创建大小为256M的空文件

dd if=/dev/zero of=tf_image bs=1M count=256 文件分区操作

# 1M,16M,c 表示 # start : 1M # size : 16M # MBR 分区ID : c # ,,L 表示 将扩展分区全部划成逻辑分区 cat <<EOT |sudo sfdisk tf_image 1M,16M,c ,,L EOT # 分区结构 Disk /dev/loop25: 256 MiB, 268435456 bytes, 524288 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0x517353ca Device Boot Start End Sectors Size Id Type /dev/loop25p1 2048 34815 32768 16M c W95 FAT32 (LBA) /dev/loop25p2 34816 524287 489472 239M 83 Linux 将文件挂载为loop设备

losetup -f tf_image 格式化分区

mkfs.vfat /dev/loop25p1 mkfs.ext4 /dev/loop25p2 将uboot镜像烧录到文件头部8K偏移处

dd if=u-boot-sunxi-with-spl.bin of=/dev/loop25 bs=1024 seek=8 dd if=u-boot-sunxi-with-spl.bin of=/dev/sdb bs=1K seek=8 挂载loop设备

mount /dev/loop25p1 boot/ mount /dev/loop25p2 rootfs/ 编译boot.cmd

外部程序导入

取消挂载，并移除loop设备

umount boot/ && umount rootfs && losetup -d /dev/loop25 将启动镜像烧录进容器
