I have been working this issue for a couple of days now. Checking to make sure that I have my TFTP server set correctly (XINETD). I have checked the ARP settings and all parameters that I can think of. Went through all of the forums and can’t find a fix. Connection times out at boot and I can not Boot tftp_kernel. printenv shows every thing that is there should correct according to the developer page.

I am using Minicom ubuntu 10.4

sorry for the long post this is all the info I know to give at this point.
