我的情况更糟，连这行都没出就不动了： Please press Enter to activeate this console ctrl+c, ctrl+z都试过了，我把ctrl+a一直到ctrl+z都试了一遍，都没反应。 我的硬件是：2440，linux版本：2.6.38.6 后来在asm_do_IRQ添加了监视进程的代码： static int cnt=0; if(irq==30) { cnt++; if(cnt==5*HZ) { cnt=0; printk("%s : pid = %d, task_name = %s\n",__func__,current->pid,current->comm); printk("pc = %08x\n",regs->ARM_pc);//打印pc值 } } 每隔5秒会打印出一条： asm_do_IRQ : pid = 0, task_name = swapper pc = c0126144 swapper是空闲进程，表示系统工作是正常的，就是不让输入。有贴子说是timer4的原因，我看到timer4的响应函数直接调用timer_tick，好像后来的版本都做了很多改进，不再直接调用timer_tick，而是以事件的方式。具体还不清楚。我现在也不知道如何分析，更不知道如何处理这个难题。 愿意讨论的加我QQ：2947868523

Zynq7020 去掉“Please press Enter to activate this console”以及软件开机启动的注意事项
这个应该不止适用于Zynq7020，其他的也是适用的。在很多时候产品肯定是要做到开机自启动的，那么只要是用busybox编译出来的文件系统就会出现这样的一个问题，内核跑完之后进入文件系统就会有这句“Please press Enter to activate this console”，但这样一来用户还需要敲键盘才能进文件系统，这个就需要解决，解决办法如下： 1、进入etc目录 2、创建ini...

在s3c6410中自启动Qt应用程序，最先的想法是有/etc/init.d/rcS加入应用程序或者脚本命令就可以实现开机自动运行，不过出现了问题，启动了Qt应用程序，7寸屏幕界面中，如果点击界面会出现界面叠加的情况，也就是当前界面会被破坏，出现原来的底层界面。于是把Qt应用程序放到/etc/profile中自己开机启动的程序，但是不能自启动，需要在超级终端敲回车，"Please press Ent
