Wilson,
Judging from your ip addresses used it looks like you have a local
router. I have noticed that u-boot first tries to download the uImage from the
gateway = router first before it tries the TFTP server you actually specified in
the u-boot environment variable (serverip variable). Some routers (like my
linksys wrt54g) use tftp for updating the flash which is why they have tftp
server, but their server of course doesn't have your uImage.
This could be your
problem as I can see the client tries to download the uImage from 192.168.3.1
(which likely is your router). I haven't found a way
around this issue other than to specify the ip adress manually (ipaddr variable)
followed by the tftpboot command to download the image (and not use the dhcp
command at all). This works for me.
Regards,
Niclas
