Thanks Burts. Intereseting fact: 3850 was having default Block size of 512 and it didn't work. Then I changed block size to 8192 on 3850 and result was same as step1. Finally I changed again to 512 on switch and it worked. Thanks

Now issue have been resolved by using the command; "ip tftp blocksize 512" I dont undersatnd why cisco says that " By default , the Catalyst 3850 uses a TFTP block size value of 512 " Thank all of you.
