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.
