QSPI flash read write
This example application shows how to use the QSPI Peripheral library to perform erase, write and read operation with the QSPI Serial Flash memory in Quad IO mode.
Description
This example uses the QSPI peripheral library to erase and write an array of values to the QSPI Serial Flash memory. It verifies the value written by reading the values back and comparing it to the value written.

Setting up SAMA5D2 Xplained Ultra Evaluation Kit
Setting up the board
- Short jumper JP2 (DEBUG_DIS)
- Connect the Debug USB port on the board to the computer using a micro USB cable
Running the Application
- Build the application using its IDE
- LED indicates success or failure:
- The LED is toggled when the value read from the QSPI Serial Flash memory matched with the written value
- The LED is turned ON when the value read from the QSPI Serial Flash did not match with the written value
Refer to the following table for clock output pin and LED name for different boards:
