Hello Badri--
I can run the search.out program now! Thank you so much!! Stopping auto boot of uboot is the key.
I still have problem converging all three values, i.e. RD DQS Gate, RD DQS, and WR DQS, for each byte. If you have any suggestion for that, I would really appreciate. But as far as running the program is concerned, the problem is solved. Thank you again for your patience and detailed instruction.
