经过前面的几篇文章，如果您认真看了，至少我们可以清楚的知道，
Yocto 项目中，Kernel 是如何编译的，以及Kernel 的Image.bin、Image_nobt.dtb、modules.tgz 这三个文件分别又包含了什么内容。
可能您会说，我是清楚了这些，但问题来了，具体项目中Kernel 该怎么配置，怎么修改，怎么调试，我都不知道呀。
对此我想说，是的，别急呀，路要一步一步走，代码也要一行一行来看，我们目前还处于熟悉代码的阶段呢，
我们当前阶段的目标是：对整套代码每个目录都相对熟悉，知道其大概的作用，以及知道后续要使用的相关镜像都是怎么生成的^_^
至于，各模块的代码架构，以及项目中详细的调试方法，哈哈，放心吧，这些后续我会一篇一篇更新的，加油。
我们知道 Yocto的主要好处便在于可以灵活定制 linux kernel 及rootfs文件系统，
那本文，我们就来看看yocto中 rootfs文件系统是怎么生成的，
了解清楚 rootfs文件系统的生成原理 还是比较重要的，因为在实际项目中经常会有修改rootfs文件系统的需求。
好，废话不多说，开始吧^_^
1、core-image-base-x9h_ref_serdes.rootfs.ext4 生成 ext4 格式文件
在log中搜索下，core-image-base-x9h_ref_serdes-20220504093115.rootfs.ext4

我们来简化下上面的命令：
# 1. dd命令将从zero设备中创建一个内容为0，大小为 297305kb 的文件 core-image-base-x9h_ref_serdes-20220504093115.rootfs.ext4 dd if=/dev/zero of=core-image-base-x9h_ref_serdes-20220504093115.rootfs.ext4 seek=297305 count=0 bs=1024 # 2. 获取文件大小为 304440320 字节 stat -c %s core-image-base-x9h_ref_serdes-20220504093115.rootfs.ext4 # 3. -F 强制格式化 -i 每个inode 4096字节 -b block_size 4096字节 mkfs.ext4 -F -i 4096 -b 4096 core-image-base-x9h_ref_serdes-20220504093115.rootfs.ext4 -d ~/yocto/build-x9ref/tmp/work/x9h_ref_serdes-sdrv-linux/core-image-base/1.0-r0/rootfs # 4. 自已检查修复为 ext4的文件系统类型 fsck.ext4 -pvfD core-image-base-x9h_ref_serdes-20220504093115.rootfs.ext4
前面几条指令都好理解，问题来了，第三条，mkfs.ext4 xxx -d xxxx 这个我真没理解，没看到有 -d 这个参数呀。
结果使用代码中编译好的mkfs.ext4 --help 看了下，还真有 -d ，指定 root-directory 的意思，牛逼了

这就很好理解了，先用 mkfs.ext4 对core-image-base-x9h_ref_serdes-20220504093115.rootfs.ext4 强制进行格式化，然后再将rootfs中的文件按 ext4格式放到根目录上
好了，截止目前，我们算是看懂了，core-image-base-x9h_ref_serdes-20220504093115.rootfs.ext4 这个文件怎么来的。
