@AhmadZMQ
It seems the board's serial port exists some problem.
Can you find the serial port number in the device manager?
If not, please install the ch340 driver, you can download it from
https://github.com/UCTRONICS/Drivers.git
If still not work, please contact our salesman to give you a replacement.

Thanks for your reply, Yes, port no shows in device manager...
