IWR1443: Chirp Profile design

Hi,
I am designing an IWR1443 application with the following specifications :

Range of the object : 300m
Range Resolution : 33 cm
Sampling Frequency : 5MHz
Beat Frequency : 500KHz for 120m target
Number of Range Bins : 1024
ADC output : 12 bits
using 1Tx and 2 Rx antennas.

For the above specification, i have designed the configuration. 

sensorStop
flushCfg
dfeDataOutputMode 1
channelCfg 3 1 0
adcCfg 0 1
adcbufCfg 0 1 0 1
profileCfg  0 77 2 4.5 207.38 0 0 2.27 1 1018 5043 0 0 30
chirpCfg 0 0 0 0 0 0 0 1
frameCfg 0 0 1 1 1018 1 0
sensorStart



For reference, I am using mmw demo code. In the code i am calculating 1D FFT. I want sensor to work such that, after one chirp tx and rx, HWA calculates 1024 point FFT and then notifies the sensor to stop.
The bins are then stored in radar cube memory and thereafter transferred over the UART. I have designed the code accordingly. BUT the problem is for the above config, I do not obtain any data on UART. 
It seems like there might be some issue with the config. 
1. How do i validate the correctness of the config?
2. HOw to deisgn Frame only to compute 1D FFT.

A sample profile used from estimater seems working as it sends data out on UART but unable to verify its correctness. 

3. How to configure the estimater for 1DFFT Computation? 

Thanks,
Shailendra
