OSPI Flash IO
Introduction
This example demonstrates basic read write to the OSPI flash configured in polled mode of operation. 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. The read back data is then compared with the written known data. This is done twice at different offsets.
When both the comparisons match, test result is passed otherwise failed.

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 a Hello World example for flashing the application.
