OSC connection timeout on fmcomms5 + zcu102

Hello. We have a radio project need to use fmcomms5 on zcu102 board. So we cut the SMA connector which is blocked by an inductor near ZCU102 FMC port and install fmcomms5 on zcu102. Then I modify the devicetree file based on "arm64: dts: Add ZCU102 FMCOMMS5 support · analogdevicesinc/linux@74c6611 · GitHub" and load it onto SD card. It can successfully boot onto the Linux shell and logging information seems fine. The OSC program can be executed and looks exactly the same as it under ZC706 environment. But it will display "Error while reading data: Connection timed out "when I use OSC to plot realtime receiving waveform on any channel or do receiving function calling. The transmitting function on OSC does not work either. The other SPI based functions are normal and all 8 devices can be found under " /sys/bus/iio/devices/ ". My Xilinx environment is Vivado 2017.2.1. I assume it somehow should work otherwise there is no reason to have an existed zcu102 project under fmcomms5 directory. So is there any solution to this problem? Thank you for the help.
