只刷写内核，为何无法启动

我用了原装的Bootloader和自己编译的内核，可是总是启动不了。下面是调试信息，麻烦各位帮帮忙。

看log纤细文件系统没有挂载上，用光盘自带的内核可以吗

光盘自带的可以,自己编译以后就不行了,用的iTop4412defconfig都不行

topeet_sky

用的什么系统？内核目录下有android，linux，ubuntu的config配置文件，用对应的配置文件编译

我是全功能的底板，Android，使用的config_for_scp_db_6050_CAN 也是启动不了。。
难不成是bootloader的问题

你重新分区，然后所有镜像整个都烧写一遍试试
