Introduction

This example demonstrates basic read write to the OSPI flash configured in polled mode of operation along with an XIP component. APIs from flash driver are used to read and write to the flash. The underlying OSPI reads and writes are taken care by the flash APIs.

The example writes known data to a particular offset in the flash and then reads it back. Before and after this, a CRC calculation using an LUT which is in flash.

When both the comparisons match, test result is passed otherwise failed.

Supported Combinations

Parameter	Value
CPU + OS	r5fss0-0 nortos
Toolchain	ti-arm-clang
Board	am64x-evm, am64x-sk

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
