But there are some questions.First let me introduce my heardware:
I use powerpc+flash+sdram to buildup a mini system,use u-boot 1.1.4 as bootloader then I need to replant the kernel on it .
The linux-2.4.32 kernel which was made a uImage, is running in this mini system, the question is appear:
    Image Name:   Linux-2.4.32
   Created:      2007-08-16  21:31:03 UTC
   Image Type:   PowerPC Linux Kernel Image (gzip compressed)
   Data Size:    685809 Bytes = 669.7 kB
   Load Address: 00000000
   Entry Point:  00000000
