Zero V3s 全过程编译BSP，使用sunxi-fel启动系统问题

大帅 · 2021-04-14 15:13:25

编译BSP系统参考： https://whycan.com/t_682.html

1. 编译uboot
2. 生成boot.scr文件
编写boot.cmd
setenv bootdelay 0
setenv bootargs "console=ttyS0,115200 panic=5 rootwait root=/dev/ram0 rdinit=/linuxrc earlyprintk rw"
setenv bootm_boot_mode sec
setenv machid 1029
bootm 0x41000000
制作：
tools/mkimage -C none -A arm -T script -d boot.cmd boot.scr
3. 生成 script.bin文件
使用qianhao提供的sys_config.fex
fex2bin sys_config.fex > script.bin
4. 编译文件系统
使用https://buildroot.org/downloads/buildroot-2017.08.1.tar.gz

Filesystem images 制作rootfs.cpio.gz

x x * cpio the root filesystem (for use as an initial RAM filesystem) x x
x x Compression method (gzip) --->

编译完成后，生成output/images/文件夹下的rootfs.cpio.gz
制作ramfs
mkimage -A arm -T ramdisk -C none -n uInitrd -d rootfs.cpio.gz rootfs.cpio.gz.uImage

5. 编译内核
cp lichee_BSP_config .config
配置内核

General setup --->
x x * Initial RAM filesystem and RAM disk (initramfs/initrd) support x x
x x (/home/osboxes/v3s/licheezero/rootfs/rootfs-bin) Initramfs source file(s)
x x (0) User ID to map to 0 (user root) x x
x x (0) Group ID to map to 0 (group root) x x
x x * Support initial ramdisks compressed using gzip x x

x x [ ] Support initial ramdisks compressed using LZMA x x
x x [ ] Support initial ramdisks compressed using XZ x x
x x [ ] Support initial ramdisks compressed using LZO x x
x x Built-in initramfs compression mode (None) --->

其中/home/osboxes/v3s/licheezero/rootfs/rootfs-bin目录下存放制作好的rootfs.cpio.gz
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- uImage -j8

上电进入FEL模式运行：
sunxi-fel.exe -p uboot u-boot-sunxi-with-spl.bin write 0x41000000 uImage write 0x41d00000 script.bin write 0x41e00000 boot.scr write 0x41A00000 rootfs.cpio.gz.uImage

系统启动后停在

你得给个合适的根文件系统

大帅 · 2021-04-14 17:00:24

不明白为什么设备树必须写到这个位置？ write 0x41d00000 script.bin

大帅 · 2021-04-16 15:02:48

问题解决！随后更新Ramdisk启动方式，制作详细步骤

由于BSP驱动比较全，使用比较方便，所以优先使用，看到晕哥制作的FEL启动系统很方便，所为也要为BSP做了FEL方式启动整个系统，但遇到了问题，纵观整个论坛都是主线的方式，解决问题反复摸索的时间比较长。。。

大帅 · 2021-04-16 15:59:04

1. 让BSP从ramdisk根文件系统启动

1.1 修改内核配置选项
make ARCH=arm menuconfig
打开配置菜单，修改配置项

Ramdisk方式需要清空Initramfs source file(s)

之所以(4096)是因为我之后制作的ramdisk是4096KB大小的。
如果这个大小和你做的ramdisk不匹配，则启动时仍然会出现 kernel panic，提示ramdisk格式不正确，挂载不上ramdisk。

注意：ramdisk是一种内存虚拟磁盘技术，实质上并不是一种文件系统，它使用的文件系统是ext2文件系统。

1.2 文件系统配置

其中Toolchain path是kernel的交叉编译链的位置
kernel的版本，在交叉编译链下面查看：
libc/usr/include/linux/version.h
我这里的 LINUX_VERSION_CODE 版本是 262144
将262144转换16进制40000
我的编译链版本是4.0.0

保存配置开始编译
编译完成后生成根文件系统

2. 修改内核启动参数
2.1 安装mkimage

sudo apt install mkimage

采用修改u-boot的bootargs环境变量来传递启动参数
修改bsp.cmd文件：一键制作boot.src.7z

2.2 安装sunxi-tools工具，制作script参数配置

git clone -b v3s https://github.com/Icenowy/sunxi-tools.git
make && sudo make install

一键制作script参数配置bin文件
一键制作script.bin.7z

3. 制作ramdisk镜像
安装工具： sudo apt install genext2fs
编译buildroot
cd 到 buildroot/output 执行

$ genext2fs -b 4096 -d target/ ramdisk
$ gzip -9 -f ramdisk

制作出镜像
builtroot/output/ramdisk.gz

到此制作出全部启动文件： boot.scr script.bin u-boot-sunxi-with-spl.bin ramdisk.gz uImage
