Introduction

This application demonstrates the IPC communication between Main Domain and MCU Domain cores(mcu1_0 and mpu1_0) using two SPI instances which are connected internally. Simulates transmission and reception of messages of data size 4 bytes.

Dependencies

Master Application

This application depends on multiple components and are detailed in sections below

TI RTOS : Uses Task, semaphore, Interrupt Handling HWI and Profiling Utility.
MCAL
- Spi Driver
MCAL BSW Stubs Stubs at (SDK Install Directory)/mcusw/mcuss_demos/Bsw_Stubs are used.
MCAL Configurations Spi Configurations at (SDK Install Directory)/mcusw/mcuss_demos/mcal_config are used.
The MCAL Spi driver based Master application used for profiling is hosted on mcu1_0.

Slave Application

This application depends on multiple components and are detailed in sections below

TI RTOS : Uses Task, Semaphore, Interrupt Handling HWI and Swi.
PDK
- Spi Driver
Slave application is hosted on mpu1_0.

Requirement Id: MCAL-1020
