Memory driver synchronous - MX25L QSPI and AT25DF SPI flash read write
This example application shows how to use the Memory driver in synchronous mode to perform block operations on the MX25L QSPI flash and the AT25DF SPI flash media.
Description
This application uses multi instances of the Memory driver to communicate with the MX25L QSPI flash and the AT25DF SPI Flash memories in synchronous mode of operation in RTOS Environment. It performs block Erase/Write/Read operations on both the media. The application consists of three tasks which are called in the RTOS thread context:
APP_MX25L_Tasks() : Performs operations on the MX25L QSPI Flash Memory. APP_AT25DF_Tasks() : Performs operations on the AT25DF Flash Memory. APP_MONITOR_Tasks(): Monitors the state of above two Tasks.

Setting up AT91Bootstrap loader
To load the application binary onto the target device, we need to use at91bootstrap loader. Refer to the at91bootstrap loader documentation for details on how to configure, build and run bootstrap loader project and use it to bootstrap the application binaries.
Setting up the hardware
The following table shows the target hardware for the application projects.
| Project Name | Board |
|---|---|
| sam_a5d2_xult_freertos.X | SAMA5D2 Xplained Ultra Evaluation Kit |
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
- Make sure that the jumper JP9 is removed (jumper pins are not shorted)
Running the Application
- Build the application using its IDE
- LED is turned ON when the data read from each media matches with the data written in them
Refer to the following table for LED name:
| Board | LED Name |
|---|---|
| SAMA5D2 Xplained Ultra Evaluation Kit | RGB_LED(Green) |
