Introduction

This example demonstrates how to check the version of SYSFW running on the Cortex R5 (DM R5) at run time. Since this is frequently done by bootloaders as a sanity check, there is an API included in the Sciclient driver for checking the SYSFW version.

However, in this example this API is not used, instead the basic Sciclient_service API is used to send a "GET VERSION" request to the SYSFW and get a response back and print it out.

We also fetch the clock frequency of the current CPU using Sciclient and print that out as well, as additional sanity check.

Supported Combinations

Parameter	Value
CPU + OS	m4fss0-0 nortos
	r5fss0-0 freertos
Toolchain	ti-arm-clang
Board	am62x-sk, am62x-sk-lp, am62x-sip-sk
Example folder	examples/drivers/sciclient/sciclient_get_version

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

Attention

As the wake-up R5 is the device manager, it needs to be started by the SBL. So it can not be loaded through CCS. It should be flashed and booted through SBL.

• Refer Flash an example application for flashing the application.
