[U-Boot-Users] Why my image isn't boot?

[Zhao Hongda]

I use the u-boot cvs source,
linux-2.4.19 kernel, arm-linux patch, and xscale patch.
arm-linux-gcc 3.0 as complier,lubbock(pxa250) as platform.

    arm-linux-objcopy -O binary -R .note -R .comment -S vmlinux linux.bin
    gzip -9 linux.bin
    mkimage -A arm -O linux -T kernel -C gzip -a 0xa0008000 -e 0xa0008000 -n
"Linux Kernel Image" -d linux.bin.gz uImage
then under u-boot:
    =>loadb 0xa0008000 (send the uImage)
    =>go 0xa0008000
    start the application at 0xa0008000
    <hang>

Could someone help me about this? Thanks a lot.
