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>

You try to start a compressed kernel from RAM?
