为什么uboot会停在“booting the kernel”处?

各位高手,为什么会停在“booting the kernel”这个地方?板子是mini4020。
------解决方案--------------------
因为kernel启不来,你编译对了,可以解压,但是不能用。通俗点讲就是真正进入kernel时的二进制不能跑,不出意外的话是编译配置错。
------解决方案--------------------
你要是买的官方mini的板子 自带的代码不会这样的
这种情况最可能的是uboot传递给内核的板子类型编号和内核支持的板子编号不一致
好久没用arm了 具体名字记不住了 但是你的手册里应该有说明,教你如何修改一个跟板子型号相关的环境变量
