Tool/software:

Hi 

I am using AWR2243Boost + DCA1000EVM,

i just want some clarity in term of AWR2243 configuration over SPI, 

How does it happen by DCA1000EVM?

How USB converts into SPI over FTDI, any special TI Based , software / firmware is needed?

and there is a another USB on AWR2243Boost , what is the role of that USB?
