Introduction

This example demonstrates the usage of the MCRC module. The example shows how to setup and use the MCRC controller in the semi mode of operation. Shows the generation of matching CRC as well as non-matching signature due to insertion of error in the block of information on which the CRC is being performed or in the signature provided to the PSA Signature Register (or both, depending on the mode).

Use Cases

Use Case	Description
UC-1	Semi CPU-mode signature compute for Channel 1 and comparison against known value.
UC-2	Semi CPU-mode signature compute for Channel 2 and comparison against known value.

Supported Combinations

Parameter	Value
CPU + OS	r5fss0-0 nortos
Toolchain	ti-arm-clang
Board	am62x-sk
Example folder	examples/sdl/mcrc/mcrc_semi_cpu/

Steps to Run the Example

• When using CCS projects to build, import the CCS project for the required combination and build it using the CCS project menu (see Using SDK with CCS Projects).
• When using makefiles to build, note the required combination and build using make command (see Using SDK with Makefiles)
• Launch a CCS debug session and run the executable, see CCS Launch, Load and Run
