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:

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?
