Uncompressing Linux..done, booting the kernel后暂停        


Linux 2.6 Freescale MXC processor


Choose an option from below:

1. Load kernel to RAM and then boot from [0x80008000]
2. Change kernel loading address [0x80008000]
3. Enter command line option for kernel

Please enter selection -> Timeout occured

==========booting the kernel.==========

最后一行是自己加在代码里的。到这就死了，IMX31芯片很热，估计是死循环了。
Nandboot loader默认选1,从0x80008000启动内核.
内核版本2.6.25
启动参数是：console=ttymxc0,115200 noinitrd root=/dev/mtdblock2 rw rootfstype=jffs2 ip=off
查了一下原因:内核配置 启动参数 串口驱动等等。试过后依旧。
大家帮忙啊。

MACH_TYPE的问题？

emmoblin

boot kernel后能不能添加打印呢？
不行就使用gpio点灯吧，看执行到哪了

hotjuly

mach_type是(mx31ads)447 与nandbootloader 一样

T-bagwell

那能否判断是否进入了start_kernel？

更改console=mxcuart,0x43f90000,115200n8启动参数设置, 使用early console后显示：

死在这了。看起来是一些初始化错误。

起来了？

hotjuly

死在这了。初始化错误。

T-bagwell

同意楼下的说法

既然能打印了，就加打印语句调试吧。
在仔细看看初始化的配置
