请教 buildroot-tiny200 (F1C100/200s) 开发包，只要勾选ffmpeg，文件系统就出问题
首先感谢aodzip大佬分享的开发包，让我这个菜鸟编译系统顺利了n倍，感谢晕哥提供的平台和各位大佬的帮助。
最近想跟着逸俊晨晖大佬的帖子，跑一下视频硬解码，结果每次编译后文件系统的挂载都有问题，后来发现只要在菜单勾选ffmpg选项，哪怕只选择h264解码也不行。（编译的文件系统14M左右）
看报错unable to read id index table是分区表没找到，导致挂载文件系统失败？
看论坛的帖子，知道开发包的文件系统分squashfs只读文件系统和overlay分区的可写文件系统来实现可读可写，会不会是文件系统变大超出分区了？
0x000000000000-0x000000080000 : "u-boot"
0x000000080000-0x000000600000 : "kernel.itb"
0x000000600000-0x000004600000 : "rom" //squashfs只读文件系统
0x000004800000-0x000007800000 : "overlay" //jffs2文件系统
应该改 buildroot-tiny200/board/allwinner/generic/genimage-nand.cfg nand镜像分区配置？
还是改 buildroot-tiny200/board/allwinner/generic/uboot.env
buildroot-tiny200/board/allwinner/generic/legacy/uboot.env 里面的环境变量？
板子：MangoPi R3 128M nand版
环境：buildroot-tiny200 (F1C100/200s) 开发包
下面是勾选配置和完整启动信息，那位大佬知道的话还请指点一二 ^_^!

嗯嗯，多谢晕哥解答，这是生成的镜像大小
是改 /board/widora/mangopi/r3/devicetree/linux下的devicetree.dts么？把ram分区调大么？

};
};
};哇酷小二 说：
应该是squashfs根文件系统系统超大了，你看下文件系统镜像文件多大，然后改dts文件，应该就可以了。
