How can i build a tftp server in u-boot?

Hi smcnutt!

thank you for you help.

my english is very poor, I don't discribe my problem clearly.

why do i must change my PC ip to download the image file? the reason as follon:

first, i don't want to use the command line in u-boot.

second,Maybe,I download the image file in diffrent PC

for example,the ip of my embed board is 192.168.168.1

I set the serverip=192.168.168.100

now if the ip of my pc is 192.168.168.99

in this case, if i want to download my image file, i must use the command line of u-boot to change the env serverip or i change the ip of my pc to 192.168.168.100

,or i will no way to download my image file.

if i have a tftf server in u-boot. i can input the command "tftp -i 192.168.168.1 put image.rom" in the cmd in my pc.

do you understand?
