1.在路径 /trunk/tools/firmware-utils/src/mktplinkfw.c 这个文件里边有个“fw max len”，默认3c0000是4M的，请改成7c0000 （这一步把固件最大限制改成8M）,如果是16mflash,请改成fc0000(最大限制改成16m)。
2、修改target/linux/ar71xx/files/arch/mips/ar71xx/mach-tl-wr841n.c（找相应文件）

全部恢复后再 ./scripts/feeds update -a 安装最新源码 ./scripts/feeds install -a
更新版本号 svn up
进入编译组件包菜单 make menuconfig
开始编译 make V=99
