the problem rised on the first stage of transfering small file such as text, image, or binary. even, its size is not bigger than 20kb.
On screen of the Minicom, To send a file from PC to zedboard running linux which was contained originally at manufacturing stage, I pushed coincidentally ctrl key and A or maybe S. I can't remember exactly but, anyway, It was certain to transfer a file.
the matter was a message indicating failure of sending the file, "timeout" appeared even though it slightly had never been moved to the target board, that means zero byte.
How shoud I do to trasfer it?
