On windows is better to use teraterm terminal instead of hyperterminal.

that's correct behavior. loads command read srec from command line in u-boot,
but why do you want to use it? Your board has net interface you can use it. just
tftp command + tftp server on your x86.

hmmm. I am checking it.

As I wrote in any previous email.
Just load bitstream to FPGA connect through xmd and load linux kernel directly
without any serial communication. (dow -data ...) Just look at serial line.
That's all!!!
