硬件为mx6q_sabreauto，求Linux启动执行函数顺序（已解决）

sanrenzilaiye · 发表于 2014-7-22 15:49:09

linux 启动的顺序在哪里可以查到啊？发现启动时候程序老是死在某个地方。想通过终端查出来死在了哪里。

我知道答案目前已有6人回答

楼主你好，这不知道你指的启动顺序是什么，一般给板子上电以后，首先启动的是u-boot，然后是Linux 内核，最后起来的是文件系统。请问你这里启动时候是停在哪里的呢？你把你的logo给我看一下。

先是bootloader,再加载linux kernel, 在加载文件系统,bootloader前死机还是之后死机的呢

是U-boot启动完了之后，kernel起来之后死机的啊。所以我想知道，内核函数调用的顺序啊。

就死在了上面这个地方。难道是因为U-boot的IPU DI与Kernel的IPU DI不对应的问题吗？
