求解:6467T 内核启动不了



DSP是6467T,    uboot  kernel,  rootfs都烧写进nor flash了。nor flash是32MB(0x42000000~0x44000000)的。uboot启动起来了,但是在启动kernel时停住了, DDR是64MB(0x80000000~0x84000000)的

这是串口打印的信息:

In:    serial
Out:   serial
Err:   serial
ARM Clock :- 495MHz
DDR Clock :- 396MHz
Hit any key to stop autoboot:  0
## Booting image at 80070000 ...
   Image Name:   Linux_kernel
   Image Type:   ARM Linux Kernel Image (uncompressed)
   Data Size:    1358736 Bytes =  1.3 MB
   Load Address: 80070000
   Entry Point:  80070000
   Verifying Checksum ... OK
   XIP Kernel Image ... OK

Starting kernel ...   ////////就停在这不动了。

Uboot的参数配置:

#define CONFIG_BOOTARGS    "mem=32M console=ttyS0,115200 noinitrd root=/dev/mtdblock2 rw rootfstype=jffs2 init=/linuxrc"

#define CONFIG_BOOTCOMMAND   "cp.b 0x42040000 0x80070000 0x14BBD0;bootm 0x80070000"

请教下,是参数配置有问题吗,还是别的地方可能有问题?我应该如何修改呢,谢谢~~~
