Hello ​Wenbin Toh:

Since you're using an X-series device, I would recommend that you use the
latest version of UHD, which is 3.7.2. I would also suggest building it
from source. You can get the tar-ball at the link below.


After you upgrade UHD, you will need to run "usrp_x3xx_fpga_burner" to burn
the 3.7.2 FPGA image onto your X310 device.
