Introduction

This example demonstrates usage of the SDL ROM Checksum. This example is used to check the integrity of the data. Its work is to take a set of data associated with the memory regions of ROM and perform checksum on that data and then compare that resultant data value against a pre-determined golden vector value (golden vector has the expected value which should come as a result of 512-bit of hash message, golden vector is already defined and it has fixed address in ROM region).

Use Cases

Use Case	Description
UC-1	Calculate ROM CHECKSUM from R5F Core.

Supported Combinations

Parameter	Value
CPU + OS	r5fss0-0 nortos
Toolchain	ti-arm-clang
Board	am243x-evm
Example folder	examples/sdl/rom_checksum/

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
