Hey Wolfgang,
Here is the printenv of my u-boot, it seems that the MAC addresses on the development boards are set to a standard which does not change, since I got a printenv from freescale where they have the ping working and they have the same ethaddr as I do on my dev board:
Here is my printenv:
=> printenv

Here is the printenv from Freescale where they are able to successfully ping another device on their network:

We erased the flash on the board and every since then cannot get a ping reply from any deivce on our network, and we cannot ping the board

Since all the lights on the hub are on we once again know that it is able
to
detect the presence of the cable on the board. Also since the board can detect the pressense of a cable it seems to be working, at least on the physical layer. Is there anything one must do to ensure that u-boot has network support? We have built editted versions as well us just
extracting
u-boot, building it and programming it. Nothing seems to be working.
Did you check your environment settings, especially the MAC addresses? Did you use valid MAC addresses?
Best regards,
Wolfgang Denk
