AWR1642BOOST: How can I implement device initialization simply

I created a CCS project with only the main function which do nothing, and then I succeed compilation and loading it into AWR1642BOOST.
In this state,  above program is not implemented any device initialization code and interrupt handling code.

Is there a simple implementation of initializing the device and registering and activating the interrupt?

"Simple" means not to use SYSBIOS or MMWAVE-SDK.

I need a simple program to understand the device usage and behavior.

e.g. simple program is such as follows:

// Clear dss mailbox status register
*(unsigned int *)0xF0608418U = 0x00000003U;
