最初内核是可以启动的，但是无法从串口升级，通过定位是由于擦除flash扇区时，将endaddr计算错误，程序将每个扇区按64k计算的擦除结束地址（实际是128K）。当时将串口升级问题修改以后，就出现了内核无法启动的问题。

有相关经验的还请不吝赐教!

看日志的话，好像已经起来了么，帮顶！

[falloutmx]

你擦除的基地址是啥?从你贴的来看，内核已经起来了，但是找文件系统失败了

[该昵称已被占用了了了]

仅从擦flash这块看的话，可能有两种情况：
1、你擦除时，不小心把uboot的配置区被破坏了。导致uboot使用默认配置。 你检查下uboot中
bootargs的参数，重新给下。

2、就是文件系统被破坏了，重新down个到板子上，再启动试试。 （不过印象里，如果rootfs坏了，uboot在引导时候就能检查出来..）
