It could be integrated to our PC side application which can upload it the first time it connects to the target. Integrating TFTP server to our application would require it to start before the user powering up the target.
It might be a good idea that you explain how your users handle your board; in which cases is it important that the board is powered on _before_ the upload program was started?
With TFTP client approach, I need to set the serverip environmental variable to IP of PC with the TFTP server. If I move the controller to another room, and found out that the PC with TFTP server is not powered up, I need to either change the serverip variable to the new PC I intended to use or go back to the other room and power up the PC. :)
Or you can use DHCP/BOOTP to find your host pc (a dhcp server could be included in the upload program as well). Ok - this might find your company's DHCP server instead of your upload program, but that could surely be fixed with some special DHCP option and a small u-boot shell script which checks for the "correct" magick string.
