AD9361 PCB Calibration TIMEOUT problem

We have a AD9361 PCB board based on ZedBoard2.  It works fine until it suddenly shows following:

                          ad9361 spi32766.0: Calibration TIMEOUT (0x287, 0x2)

 

Then we measured and got

==> in_voltage2_raw <==1345

 

==> out_voltage2_raw <==306

 

==> out_voltage3_raw <== 306

 

What could be the problem?

 

Thanks in advance.
