static uint8_t QSPI_WriteEnable (QSPI_HandleTypeDef *hqspi)
 This function send a Write Enable and wait it is effective.
static uint8_t QSPI_AutoPollingMemReady (QSPI_HandleTypeDef *hqspi, uint32_t Timeout)
 This function read the SR of the memory and wait the EOP.
static uint8_t QSPI_EnterQPI (QSPI_HandleTypeDef *hqspi)
 This function enter the QPSI memory in QPI mode.
uint8_t BSP_QSPI_Init (void)
 Initializes the QSPI interface.
uint8_t BSP_QSPI_DeInit (void)
 De-Initializes the QSPI interface.
uint8_t BSP_QSPI_Read (uint8_t *pData, uint32_t ReadAddr, uint32_t Size)
 Reads an amount of data from the QSPI memory.
uint8_t BSP_QSPI_Write (uint8_t *pData, uint32_t WriteAddr, uint32_t Size)
 Writes an amount of data to the QSPI memory.
uint8_t BSP_QSPI_Erase_Block (uint32_t BlockAddress)
 Erases the specified block of the QSPI memory.
uint8_t BSP_QSPI_Erase_Chip (void)
 Erases the entire QSPI memory.
uint8_t BSP_QSPI_GetStatus (void)
 Reads current status of the QSPI memory.
uint8_t BSP_QSPI_GetInfo (QSPI_Info *pInfo)
 Return the configuration of the QSPI memory.
uint8_t BSP_QSPI_EnableMemoryMappedMode (void)
 Configure the QSPI in memory-mapped mode.
__weak void BSP_QSPI_MspInit (QSPI_HandleTypeDef *hqspi, void *Params)
 QSPI MSP Initialization This function configures the hardware resources used in this example:

  • Peripheral's clock enable
  • Peripheral's GPIO Configuration
  • NVIC configuration for QSPI interrupt.

__weak void BSP_QSPI_MspDeInit (QSPI_HandleTypeDef *hqspi, void *Params)
 QSPI MSP De-Initialization This function frees the hardware resources used in this example:

  • Disable the Peripheral's clock
  • Revert GPIO and NVIC configuration to their default state.

Detailed Description

This file includes a standard driver for the MT25TL01G QSPI memory mounted on STM32H747I-DISCOVERY board.

  ==============================================================================
                     ##### How to use this driver #####
  ==============================================================================
  [..]
   (#) This driver is used to drive the MT25TL01G QSPI external
       memory mounted on STM32H747I-DISCOVERY board.

   (#) This driver need a specific component driver (MT25TL01G) 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)
