Introduction

This application, internally called as AUTOSAR benchmarking application is used for benchmarking several KPIs such as:

• I-cache miss
• D-cache miss
• memory copy performance on different cores
• with options such as XIP, non-XIP
• ability to run software on other cores
• run with CCS or SBL etc.

Supported Combinations

Parameter	Value
CPU + OS	r5fss0-0 freertos
Toolchain	ti-arm-clang
Boards	am62x-sk, am62x-sk-lp, am62x-sip-sk
Example folder	examples/kernel/freertos/memcpy_benchmark/

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
