Do search the archives because my memory isn't what it used to be, but I don't recall a TFTP server coming up. Periodically FTP support comes up and then silently disappears when the requester figures out how much work it would be. Despite sharing 3/4 of the characters and supporting the same concept, TFTP and FTP are totally different animals. > I'm curious why you want to do this.

This would fit well into the u-boot restricted architecture that is characterized by being single threaded with no tasking. Trying to do a full fledged tftp server that runs independently in the background is going to be a lot harder because there is no "background" in u-boot.
