很抱歉代码的长度，任何帮助将不胜感激，我很卡住，在互联网上找不到任何东西来打击这个。
尽管我不熟悉这个平台，以及问题的时代，但我认为从引导Linux系统的角度来看，解决这个问题仍然很有帮助。如果你看看有效的系统，你至少可以得到一个线索。
“释放内存”是内核在启动init之前做的最后一件事。下一行应该是init启动并显示其版本（或任何它喜欢做的事情）。如果缺少init，就会出现内核恐慌，所以我猜init有一个问题。
所有这些都暗示着
我打算离开这里，因为我认为其他人可能会有类似的问题，而且缺乏实际答案，这是一个开始。特别是，U-Boot没有任何问题。你能做的最糟糕的事情是告诉它是用init做一些奇怪的事情，但是“init = / init”和它一样简单。
