******************************************************************************
* @file stm32h735g_discovery_ospi_nor.c
* @author MCD Application Team
* @brief This file includes a standard driver for the MX25LM51245G OSPI
* memory mounted on STM32H735G-DK board.
@verbatim
==============================================================================
##### How to use this driver #####
==============================================================================
[..]
(#) This driver is used to drive the MX25LM51245G Octal NOR and the S70KL1281 HyperRAM
external memories mounted on STM32H735G-DK board.
(#) This driver need specific component driver (MX25LM51245G and S70KL1281) to be included with.
(#) MX25LM51245G Initialization steps:
(++) Initialize the OPSI external memory using the BSP_OSPI_NOR_Init() function. This
function includes the MSP layer hardware resources initialization and the
OSPI interface with the external memory.
(#) MX25LM51245G Octal NOR memory operations
(++) OSPI 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_OSPI_NOR_Read()/BSP_OSPI_NOR_Write().
(++) The function BSP_OSPI_NOR_GetInfo() returns the configuration of the OSPI memory.
(see the OSPI memory data sheet)
(++) Perform erase block operation using the function BSP_OSPI_NOR_Erase_Block() and by
specifying the block address. You can perform an erase operation of the whole
chip by calling the function BSP_OSPI_NOR_Erase_Chip().
(++) The function BSP_OSPI_NOR_GetStatus() returns the current status of the OSPI memory.
(see the OSPI memory data sheet)
(++) The memory access can be configured in memory-mapped mode with the call of
function BSP_OSPI_NOR_EnableMemoryMapped(). To go back in indirect mode, the
function BSP_OSPI_NOR_DisableMemoryMapped() should be used.
(++) The erase operation can be suspend and resume with using functions
BSP_OSPI_NOR_SuspendErase() and BSP_OSPI_NOR_ResumeErase()
(++) The function BSP_OSPI_NOR_ReadID() returns the identifier of the memory
(see the OSPI memory data sheet)
(++) The configuration of the interface between peripheral and memory is done by
the function BSP_OSPI_NOR_ConfigFlash(), three modes are possible :
- SPI : instruction, address and data on one line
- STR OPI : instruction, address and data on eight lines with sampling on one edge of clock
- DTR OPI : instruction, address and data on eight lines with sampling on both edgaes of clock
(#) S70KL1281 Initialization steps:
(++) Initialize the HyperRAM external memory using the BSP_OSPI_RAM_Init() function. This
function includes the MSP layer hardware resources initialization and the
OSPI interface with the external memory.
(#) S70KL1281 HyperRAM memory operations
(++) HyperRAM 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_OSPI_RAM_Read()/BSP_OSPI_RAM_Write().
Read/write operation can be performed with DMA using the functions
BSP_OSPI_RAM_Read_DMA()/BSP_OSPI_RAM_Write_DMA().
(++) The memory access can be configured in memory-mapped mode with the call of
function BSP_OSPI_RAM_EnableMemoryMapped(). To go back in indirect mode, the
function BSP_OSPI_RAM_DisableMemoryMapped() should be used.
(++) The configuration of the interface between peripheral and memory is done by
the function BSP_OSPI_RAM_ConfigHyperRAM() :
- one latency mode is possible :
- Fixed latency mode
- five burst configuration are possible :
- Linear burst access
- 16-bytes hybrid burst access
- 32-bytes hybrid burst access
- 64-bytes hybrid burst access
- 128-bytes hybrid burst access
