* @file stm32746g_discovery_qspi.c
* @author MCD Application Team
* @brief This file includes a standard driver for the N25Q128A QSPI
* memory mounted on STM32746G-Discovery board.
@verbatim
==============================================================================
##### How to use this driver #####
==============================================================================
[..]
(#) This driver is used to drive the N25Q128A QSPI external
memory mounted on STM32746G-Discovery board.
(#) This driver need a specific component driver (N25Q128A) to be included with.
(#) Initialization steps:
(++) Initialize the QPSI external memory using the BSP_QSPI_Init() function. This
function includes the MSP layer hardware resources initialization and the
QSPI interface with the external memory.
(#) QSPI memory operations
(++) QSPI memory can be accessed with read/write operations once it is
initialized.
Read/write operation can be performed with AHB access using the functions
BSP_QSPI_Read()/BSP_QSPI_Write().
(++) The function BSP_QSPI_GetInfo() returns the configuration of the QSPI memory.
(see the QSPI memory data sheet)
(++) Perform erase block operation using the function BSP_QSPI_Erase_Block() and by
specifying the block address. You can perform an erase operation of the whole
chip by calling the function BSP_QSPI_Erase_Chip().
(++) The function BSP_QSPI_GetStatus() returns the current status of the QSPI memory.
(see the QSPI memory data sheet)
