When running test cases under the coupled mode, there is only output from WRF and no output from wrfhydro

I followed the example of the coupled mode from the official website to compile, replaced the 'hydro' folder, and successfully compiled WRF and WPS.

Due to a segmentation fault, I modified the time_step of WRF and successfully ran real.exe and wrf.exe. While I got all the outputs for the WRF mode, there's no output from WRF-Hydro.

Does anyone know why?

I have set "sys_cpl = 2"

The issue was resolved by reducing the version of wrfhydro from 5.2 to 5.1.1
