[U-Boot] network not work with u-boot

[cleancode at 163.com <cleancode@163.com>]

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,
