按照荔枝派nano的教程和本论坛置顶帖子的顺序，制作了完成了镜像文件，烧写进去之后，发现最后起不来
1、看打印信息，发现了spi，并且好像挂载rootfs也成功了
2、搜索本论坛，参考了一些，也取消了一些配置上的东西，不管用
3、难道是根文件系统有问题？

结贴：感谢晕哥，确实如此，编译buildroot生成根文件的时候不能再用arm-linux-gnueabi，而应该用默认下载的Sourcery CodeBench ARM 2014.5
那么我以后在PC上交叉编译C程序生成可执行文件到nano上的时候，编译器应该用哪个呢？按道理，也应该用根文件系统同样的编译器Sourcery CodeBench ARM 2014.5？
对, 你的编译器有问题, 导致根文件系统有问题:
