Installing u-boot in mini2440

while proceeding as per link given below.

http://wiki.iface.ch/index.php/Installing_u-boot_on_Mini2440

I got stuck while it comes to usbpush.

I get minicom window saying usb connected. Waiting for download.

But my usbpush part is not working. 

I had given it a thought as i am using 64 bit computer with ubuntu 12.04
and hence usbpush (32 bit binary) may not work on it. 

Further on, i tried to compile usbpush but it also shows me an error.

Please guide me through this.

Thanks.

I got solution to these problem.

There is a minor modification that has to be made in Makefile
