我正在尝试对 GPS 手表固件映像进行逆向工程，目的是为手表添加新功能。这是我到目前为止所得到的
- 我有固件映像（.gcd 文件）。AFAIK 这不是常见的图像，我无法从谷歌搜索中找到任何有关它的信息
这是binwalk输出：

这一切似乎都是误报，因为当我运行时，
binwalk -e我将这些文件作为输出：
所有没有文件后缀的文件都是空的，压缩文件会报错。（我无法解压缩 zlib 文件）
从hexdump输出中，我看到了很多 ascii，我猜这表明它没有加密。尤其是我发现在0x10780A和之间似乎有某种语言文件0x138342
我已将 hexdump 包含为 hex2.out
我的问题是：我从这里去哪里？请帮忙，我不知道。
