逆向工程 - 分析固件映像（带有 YAFFS 的 eCos） - 吾爱随笔录

我正在尝试应用我在课堂和网上学到的一些实践，并对中国行车记录仪的固件进行逆向工程。

我已经从他们的网站（智能行车记录仪：CA21L）下载了固件，作为第一步，我尝试binwalk了固件。我发现的唯一“有趣”的事情是一行，它表明binwalk认为文件中嵌入了一个 YAFFS 文件系统：

983141        0xF0065         eCos RTOS string reference: "eCos"
1503088       0x16EF70        YAFFS filesystem
1637704       0x18FD48        JPEG image data, JFIF standard 1.02

根据偏移量，我的猜测是那里有一个文件系统。但是我不知道如何挂载/提取它，因为我在这里得到的输出与大多数“固件逆向教程”的输出并不完全相同，我已经看到你在哪里获得“squashFS”和一个压缩的引导加载程序，它们可以清楚地进行 binwalk认可。在这里，除了 YAFFS 的小提示和许多指示 eCos OS 正在运行的字符串之外，我真的不知道如何处理其余的输出。

我转向这里是因为也许有经验的人可以阐明我从输出中看到的内容，我究竟如何提取文件系统（如果有的话）以及系统正在运行 eCos 意味着什么（是的我已经用谷歌搜索了它，但它的结构仍然不清楚）。

固件二进制文件的前几个字节：
