Hello,

I have a similar problem. I am trying to boot imx53 QSB via network. When I give the command run bootcmd_net in U-boot I get following messages:

MX53-LOCO U-Boot > run bootcmd_net

FEC: enable RMII gasket

PHY indentify @ 0x0 = 0x0007c0f1

Using FEC0 device

TFTP from server 172.16.98.1; our IP address is 172.16.98.3

Filename 'uImage'.

Load address: 0x70800000

Loading: FEC: Link is down 7809
