This example demonstrate's basic read write erase to the Parallel NAND flash using GPMC configured to operate in DMA mode of operation. APIs from flash driver are used to read, write and erase to the flash. The underlying 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. By deafult ELM is enabled in the example. When both the comparisons match, test result is passed otherwise failed.
An external GPMC NAND flash needs to be connected to the device.
