Sequence being followed

A. CONFIGURATION
1. Connecting to TDA
1. Configuring Master from SOP till Channel Config
2. Configuring Slave (i) sequentially from SOP till SPI Connect. i = 1, 2, 3
3. Configuring Slaves together from F/W download till Channel Config
4. Configuring all devices together from LDO Bypass till Frame Config

NOTE:
Update the following in the script accordingly before running
1. metaImage F/W path on line 32

The sensor configuration consists of 3 sections:
1) Profile Configuration (common to all 4 AWR devices)
2) Chirp Configuration (unique for each AWR device - mainly because TXs to use are 
                        different for each chirp)
3) Frame Configuration (common to all 4 AWR devices, except for the trigger mode for the master)
