[U-Boot] iMx31 Litekit U-boot not working

[Vipin Gahlaut]

Hi Experts,

I have downloaded u-boot version  u-boot-2012.07 and build it for i.Mx31
litekit board (make imx31_litekit_coinfig; make). u-boot builds fine. When
I am loading u-boot in to RAM using Logic Loader as described at following
link nothing happens. I do not get u-boot prompt.

Please see console logs below
==================
losh> ifconfig sm0 10.10.10.20 255.255.255.0 10.10.10.1
losh> ifconfig sm0 up

losh> exec 0x81000000 -

===================
Stuck at this point.

Your expert help is appreciated. I do not have JTAG device to burn it in to
flash so need to test u-boot using logic loader provided by board vendor.
