Jerome Coutant 2:123b894b49dd 4 * @author MCD Application Team
Jerome Coutant 2:123b894b49dd 5 * @brief This file includes a standard driver for the N25Q128A QSPI
Jerome Coutant 2:123b894b49dd 6 * memory mounted on STM32469I-Discovery board.
Jerome Coutant 2:123b894b49dd 7 @verbatim
Jerome Coutant 2:123b894b49dd 8 ==============================================================================
Jerome Coutant 2:123b894b49dd 9 ##### How to use this driver #####
Jerome Coutant 2:123b894b49dd 10 ==============================================================================
Jerome Coutant 2:123b894b49dd 11 [..]
Jerome Coutant 2:123b894b49dd 12 (#) This driver is used to drive the N25Q128A QSPI external
Jerome Coutant 2:123b894b49dd 13 memory mounted on STM32469I-Discovery board.
Jerome Coutant 2:123b894b49dd 14
Jerome Coutant 2:123b894b49dd 15 (#) This driver need a specific component driver N25Q128A to be included with.
Jerome Coutant 2:123b894b49dd 16
Jerome Coutant 2:123b894b49dd 17 (#) Initialization steps:
Jerome Coutant 2:123b894b49dd 18 (++) Initialize the QPSI external memory using the BSP_QSPI_Init() function. This
Jerome Coutant 2:123b894b49dd 19 function includes the MSP layer hardware resources initialization and the
Jerome Coutant 2:123b894b49dd 20 QSPI interface with the external memory.
Jerome Coutant 2:123b894b49dd 21
Jerome Coutant 2:123b894b49dd 22 (#) QSPI memory operations
Jerome Coutant 2:123b894b49dd 23 (++) QSPI memory can be accessed with read/write operations once it is
Jerome Coutant 2:123b894b49dd 24 initialized.
Jerome Coutant 2:123b894b49dd 25 Read/write operation can be performed with AHB access using the functions
Jerome Coutant 2:123b894b49dd 26 BSP_QSPI_Read()/BSP_QSPI_Write().
Jerome Coutant 2:123b894b49dd 27 (++) The function BSP_QSPI_GetInfo() returns the configuration of the QSPI memory.
Jerome Coutant 2:123b894b49dd 28 (see the QSPI memory data sheet)
Jerome Coutant 2:123b894b49dd 29 (++) Perform erase block operation using the function BSP_QSPI_Erase_Block() and by
Jerome Coutant 2:123b894b49dd 30 specifying the block address. You can perform an erase operation of the whole
Jerome Coutant 2:123b894b49dd 31 chip by calling the function BSP_QSPI_Erase_Chip().
Jerome Coutant 2:123b894b49dd 32 (++) The function BSP_QSPI_GetStatus() returns the current status of the QSPI memory.
Jerome Coutant 2:123b894b49dd 33 (see the QSPI memory data sheet)
