ppc_4xx uImage - kernel boot problem

[ayhan]

*Hello,

I have an AMCC 405gp board on which runs u-boot. I try to boot the Linux
Kernel via network but can not. I download uImage using DHCPD/TFTP. Here is
the  minicom console output:*


Type "run flash_nfs" to mount root filesystem over NFS

Hit any key to stop autoboot:  0
ENET Speed is 100 Mbps - FULL duplex connection (EMAC0)
Using ppc_4xx_eth0 device
TFTP from server 192.168.1.210; our IP address is 192.168.1.220
Filename 'uImage'.
Load address: 0x200000

   Entry Point:  00000000
   Verifying Checksum ... OK
   Uncompressing Kernel Image ... OK


*Here the console is frozen. It's the point where u-boot ends up and the
kernel code starts. I think I have a mistake in addressing. I don't have
sufficient knowledge about uImage format and the kernel compilation process.
I followed the steps through the ELDK documantation from DENX software for
cross-compiling the linux kernel as below:     *

      bash$ make mrproper
      bash$ make ARCH=ppc CROSS_COMPILE=ppc_4xx- walnut_defconfig
      bash$ make ARCH=ppc CROSS_COMPILE=ppc_4xx- uImage

*Could anyone help me solving the boot problem?*
