1.28 SQI Flash Read Write
This example application demonstrates how to use the SQI Peripheral library to perform erase, write and read operation with the SQI Serial Flash memory.
Description
This example uses the SQI peripheral library to erase and write an array of values to the SQI Serial Flash memory. It verifies the value written by reading the values back and comparing it to the value written.
