[U-Boot-Users] tftpboot question

I'm trying to use tftpboot to copy linux image into flash starting address
is 0xff300000, so I defined CFG_DIRECT_FLASH_TFTP. It looks data have been
written into flash since there is no any error. However, when I try to boot
linux, it returns gunzip error. If I download the same image using xmodem,
the kernel just boots fine. Do I need to do anything special for tftp direct
to flash? If I tftp image into ram(0x800000) then boot, it's just fine too.
