I am running uboot 1.1.5 and I have uClinux image that include kernel and romfs.  I download to my board (M5272C3 based) using tftpboot. Everything looks fine but, dhcpcd failed to get ip address and Ethernet packet transmit kept timeout.  Buffer descriptor got dumped eveny few seconds.  The same image (elf file instead of bin file) download under umon that works fine on that part.  Anyone has idea?  Oh, I have set my Ethernet address, but it did not help.

Thanks!
