按照LIcheepi Zero的“SPI系统杂谈”的顺序，编译好了所有文件，搞好了所有镜像（过程都是按照32M准备的，flash是MX25L256），
出现问题有两个：
1、用fel工具的时候，如果fel-spiflash.c文件不改动，还是用默认的最大16M，则用sudo sunxi-fel spiflash-info 命令能正常检测到32M的flash
但是按照说明改动fel-spiflash.c使其能使用32M的flash，再编译安装后，则用sudo sunxi-fel spiflash-info 命令失效，不能检测到flash
2、为了保险起见，先改回fel-spiflash.c文件到默认的16M的flash模式，同时重新制作了一个16M的镜像，下载成功，板子串口有输出，但是错误，启动信息如下：

晕哥在哪里，求助啊
第1个问题暂且不提，第2个是咋回事？
我看中间有“mount: you must be root”，难道是挂载根文件的时候需要root权限的意思？可是我是从咱文档里边直接用的推荐的配置好的rootfs-brmin的啊
搞不动了，求助

谢谢，膜拜大神，我又搞了一遍jffs2，居然成功了！
第1个问题还在想办法，
感觉还是你烧录问题, 可能是 jffs2 根文件系统不完整.
