I saw correct PAD_TO value without modification. ccache /opt/toolchains/arm-2008q3/bin/arm-none-linux-gnueabi-objcopy --gap-fill=0xff --pad-to=4096 -O binary /home/share/Work/u-boot-work/nand_spl/u-boot-spl /home/share/Work/u-boot-work/nand_spl/u-boot-spl-16k.bin and I've got 4Kbyte binary also. -rwxr-xr-x 1 prom prom 4096 2009-09-16 10:21 u-boot-spl-16k.bin I think there have no problem. If it's not your problem, please explain in more detail. Thanks.
