I have installed armboot-1.1.0 in my lubbock platform,
and use linux-2.4.17.tar.gz, diff-2.4.17-rmk5-pxa1.gz, patch-2.4.17-rmk5.gzto build my Linux kernel like following:
    (I have modified arch/arm/Makefile, let TEXTADDR=0xa0008000, the old value is 0xc0008000)
    make lubbock_config
    make oldconfig
    make dep
    make zImage
and then use mkimage to create some uImage, but none work, just as following:
   
    mkimage -A arm -O Linux -C none -a 0xa0008000 -e 0xa0008000 -n "Linux" -d zImage uImage 
the error is:
 
=> loadb 0xa0008000
## Ready for binary (kermit) download ...
## Start Addr      = 0xa0008000
=> bootm
## Booting image at a0008000 ...

    (then a lot of unrecognized char appear,and then system halt)
 
    mkimage -A arm -O Linux -C gzip -a 0xa0008000 -e 0xa0008000 -n "Linux" -d zImage uImage
