Introduction

This example demonstrate's basic read, write and erase to the Parallel NAND flash using GPMC configured in polled mode of operation. APIs from flash driver are used to read, write and erase to the flash. The flash APIs call the underlying GPMC APIs for read, write and erase function.

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

Supported Combinations

Parameter	Value
CPU + OS	r5fss0-0 freertos
Toolchain	ti-arm-clang
Board	am62x-sk
Example folder	examples/drivers/gpmc/gpmc_flash_io/

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)

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.
