IWR6843 + DCA1000EVM: SPI Status shows Disconnected In mmwave Studio

Part Number: DCA1000EVM
Other Parts Discussed in Thread: MMWAVEICBOOST, IWR6843ISK,

Hi TI Team,

We are using DCA1000EVM + MMWAVEICBOOST + IWR6843ISK. We are trying to bringup DCA1000EVM to capture raw ADC data. We are folloeing the steps mentioned in "mmWave Sensor Raw Data Capture Using the DCA1000 Board and mmWave Studio" , After flashing BSS and MSS firmware, I could observe SPI Status as :"Disconnected".

Please find the attached image showing the logs.

I will be glad if we get the solution as early as possible.

May I learn the reason for this?

Attaching the Setup image for reference.
