This is typical downloading snapshot: U-Boot> tftp 23000000 lm125/rel/1.0.0/image.ub TFTP from server 192.168.0.141; our IP address is 192.168.0.206 Filename 'lm125/rel/1.0.0/image.ub'.

Also as soon as uClinux is loaded, network applications (including NFS and TFTP) are working smoothly meaning that problem is in u-boot emaculite drivers themselves (I'm using u-boot 1.1.4 snapshot from Petalinux distro). Wolfgang Denk suggested here http://www.denx.de/wiki/view/DULG/TFTPTimeout that it can be problem with full/half duplex configuration, but I couldn't find how to configure such mode is configured for emaculite driver. Please advise, Leonid.
