When i try the flash the firmware i got the error 

Arduino: 1.8.1 (Linux), Board: "OpenCR Board, OpenCR Bootloader"

Sketch uses 174064 bytes (22%) of program storage space. Maximum is 786432 bytes.
Global variables use 45372 bytes of dynamic memory.
opencr_ld ver 1.0.2
file name : /tmp/arduino_build_196397/turtlebot3_core.ino.bin 
file size : 171 KB
Open port OK
Clear Buffer Start
An error occurred while uploading the sketch
Clear Buffer End
cmd_read_board_name fail : 0xF020

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences. 

Would you like to tell me how to solve that error. Thanks

The error code stands for "Timeout".

Make sure that you have the latest firmware version (1.0.16)

Also, please try under Firmware Recovery Mode.

Thank you

You only need to see "4.5 Firmware Recovery Mode"

The file "opencrfw.bin" mentioned in Section 5. Downloader is only an arbitrary example file name.

Since you are using Arduino IDE, you don't need to use Downloader.

If i use Arduino IDE, I follow the section 6, i burn the bootloader.
then how can i burn the firmware?
Would you like to reply me as soon as possible?

If you have successfully burned Bootloader, you can try uploading your program as you did in a normal way.

In my case sometimes it took several trials when uploading program after getting some error messages.

You might also want to try with other USB cable if you have any.
