对于代码的长度感到抱歉，任何帮助都会非常感激，我很卡住，在互联网上找不到任何可以解决这个问题的东西。
答案 0 :(得分：0)
尽管我对这个平台不熟悉，而且这个问题已经年代久远了，但从启动Linux系统的角度来看，我认为总体上解决这个问题还是有帮助的。如果您查看有效的系统，则至少可以得到一个提示。
“释放内存”是内核在启动init之前要做的最后一件事。下一行应该是init开始并显示其版本（或它喜欢做的任何事情）。如果缺少init，则会出现内核崩溃，因此我想init本身就有问题。
这就是所有的意思
我要离开这里，因为我认为其他人可能也会遇到类似的问题，并且缺乏实际答案，这是一个开始。特别是，U-Boot没错。您能做的最坏的事情是告诉它要对init做一些奇怪的事情，但是“ init = / init”几乎是很简单的。
