AM2432: How to configure TDM mode in cascade?

Hello Champs,

Customer is using mmwave_mcuplus_sdk_04_04_01_02\mmwave_mcuplus_sdk_04_04_01_02\ti\utils\test\cascade\am273x, the demo supports DDMA. He wants to change it to TDM mode. 

He modified the cfg as below:

profileCfg 0 77 7 7 20.83 0 0 11 256 20000 0 0 42
chirpCfg 0 0 0 0 0 0 0 1
chirpCfg 1 1 0 0 0 0 0 4
chirpCfg 2 2 0 0 0 0 0 2
frameCfg 0 2 16 400 256 100 1 0；

But the raw data is only half as expected. 

The expected data is =sampling (256)* 4*TX*RX(48, MIMO 6TX8RX)*chirp(16)*frame number(400).

How to configure TDM mode in cascade?

Thanks
