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 ^_^!

Re: 请教 buildroot-tiny200 (F1C100/200s) 开发包，只要勾选ffmpeg，文件系统就出问题

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？

	spi-nand@0 {
		#address-cells = <1>;
		#size-cells = <1>;
		compatible = "spi-nand";
		reg = <0>;
		spi-max-frequency = <50000000>;
		//status = "disabled";

		partitions {
			compatible = "fixed-partitions";
			#address-cells = <1>;
			#size-cells = <1>;

			partition@0 {
				label = "u-boot";
				reg = <0x000000 0x80000>;
				read-only;
			};

			partition@1 {
				label = "kernel.itb";
				reg = <0x80000 0x580000>;
				read-only;
			};

			partition@2 {
				label = "rom";
				reg = <0x600000 0x4000000>;
				read-only;
			};

			partition@3 {
				label = "overlay";
				reg = <0x4800000 0x3000000>;
			};
		};
	};

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。
