MMWCAS-RF-EVM: A question about Tx Beamforming Setting

We've already followed the page 13 of User's Guide's setting as below:

Scripts used:
1. Cacade_Configuration_Basic.lua for configuration of devices, except for Profile, Chirp, Phase Shifter and Frame configuration
2. Cascade_Configuration_TXBF_simple.lua for configuring the devices with a TX beam forming configuration
3. Cascade_Capture.lua for capturing data

But it almost didn't work.

May I ask there are something wrong in setting process ?

Thanks.
