Dear TI team

I have a question regarding SPI communication between AWR1234BOOST and  MSP430F5529. Till now all the communication was made with the PC as a host and all the examples form  dfp were working fine. We want to be independent from the PC and try to make  AWR1234BOOST start on bootup.

We saw on some other posts that others try to connect the AWR1234BOOST to MSP430F5529 to make it independent form PC. I tried to follow the the following thread: https://e2e.ti.com/support/sensors/f/1023/p/839686/3105534#3105534

We tried to implement the solution. We tried to modify the example code mmw_example_nonos.c from mmwave_dfp_01_02_05_01 but for now with no succes. Almost all the callbacks work when using rl_nonos.c but we do not know how to initialize SPI communication properly. Where could i get some sample code to initialize correctly the SPI communication between AWR1234BOOST and  MSP430F5529. 

Thank you,
