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

Hi smalllight,

Your english is fine ... and I understand your problem clearly -- I just don't

agree with your proposed solution :-)

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

You don't have to ... use the autoboot feature.

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

And that is exactly the problem (plus others) that DHCP/BOOTP & TFTP successfully

solved many years ago ... and continues to solve today. u-boot fully supports DHCP/BOOTP & TFTP.

Again, I disagree. Regardless, you have at least two choices:

1. get tftpd32: http://tftpd32.jounin.net (http://tftpd32.jounin.net)

This is what I recommend.

2. implement a tftp server in u-boot

Feel free to implement the tftp server in u-boot -- but realize that you will be

re-inventing the wheel ;-)
