Hi Sanket,
What we can provide is the GD31xx Driver Example Code, you can download it from the GD3160 website:
https://www.nxp.com/products/GD3160

The GD31xx.c file contains the GD31xx device driver functions. They consist of SPI access, initialization and register configuration functions. There is also a sample interrupt service routine for monitoring the INTB signal from the GD31xx. All low-level SPI transmit and receive functions are written for the MCP5777C MCU. These functions will have to be changed if you are using a different MCU from the S32K3 family.
BRs, Tomas
