Hi Wolfgang,
Thank you so much, I managed to upload the kernel image by using a tftp server in my desktop. I thought the tftp was a kind of ftp with a naming difference...
As for the configuration item ipaddr1, I still cannot delete it, I am not happy about that. Do you or anyone else know how to delete this kind of ill-spelled items? If not, I can accept it as it has no side-effect to the system, the uboot brings up the linux kernel every time. However, if there is a way to delete, it would make me happier.
-- Best wishes.

If what you write is correct, then this is expected behaviour.
U-Boot does not have support for TCP/IP, and so it cannot implement the FTP protocol. All we have is TFTP = TRIVIAL FTP.
You your FTP server will not help - you need a TFTP server instead.
This also explains the port mismatch you see in wireshark.
Best regards,
