| =============================================================================== |
| ##### How to use this driver ##### |
| =============================================================================== |
| [..] |
| *** Initialization *** |
| ====================== |
| [..] |
| As prerequisite, fill in the HAL_OSPI_MspInit() : |
| (+) Enable OctoSPI and OctoSPIM clocks interface with __HAL_RCC_OSPIx_CLK_ENABLE(). |
| (+) Reset OctoSPI Peripheral with __HAL_RCC_OSPIx_FORCE_RESET() and __HAL_RCC_OSPIx_RELEASE_RESET(). |
| (+) Enable the clocks for the OctoSPI GPIOS with __HAL_RCC_GPIOx_CLK_ENABLE(). |
| (+) Configure these OctoSPI pins in alternate mode using HAL_GPIO_Init(). |
| (+) If interrupt or DMA mode is used, enable and configure OctoSPI global |
| interrupt with HAL_NVIC_SetPriority() and HAL_NVIC_EnableIRQ(). |
| (+) If DMA mode is used, enable the clocks for the OctoSPI DMA channel |
| with __HAL_RCC_DMAx_CLK_ENABLE(), configure DMA with HAL_DMA_Init(), |
| link it with OctoSPI handle using __HAL_LINKDMA(), enable and configure |
| DMA channel global interrupt with HAL_NVIC_SetPriority() and HAL_NVIC_EnableIRQ(). |
| [..] |
| Configure the fifo threshold, the dual-quad mode, the memory type, the |
| device size, the CS high time, the free running clock, the clock mode, |
| the wrap size, the clock prescaler, the sample shifting, the hold delay |
| and the CS boundary using the HAL_OSPI_Init() function. |
| [..] |
| When using Hyperbus, configure the RW recovery time, the access time, |
| the write latency and the latency mode unsing the HAL_OSPI_HyperbusCfg() |
| function. |
| |
| *** Indirect functional mode *** |
| ================================ |
| [..] |
| In regular mode, configure the command sequence using the HAL_OSPI_Command() |
| or HAL_OSPI_Command_IT() functions : |
| (+) Instruction phase : the mode used and if present the size, the instruction |
| opcode and the DTR mode. |
| (+) Address phase : the mode used and if present the size, the address |
| value and the DTR mode. |
| (+) Alternate-bytes phase : the mode used and if present the size, the |
| alternate bytes values and the DTR mode. |
| (+) Dummy-cycles phase : the number of dummy cycles (mode used is same as data phase). |
| (+) Data phase : the mode used and if present the number of bytes and the DTR mode. |
| (+) Data strobe (DQS) mode : the activation (or not) of this mode |
| (+) Sending Instruction Only Once (SIOO) mode : the activation (or not) of this mode. |
| (+) Flash identifier : in dual-quad mode, indicates which flash is concerned |
| (+) Operation type : always common configuration |
| [..] |
| In Hyperbus mode, configure the command sequence using the HAL_OSPI_HyperbusCmd() |
| function : |
| (+) Address space : indicate if the access will be done in register or memory |
| (+) Address size |
| (+) Number of data |
| (+) Data strobe (DQS) mode : the activation (or not) of this mode |
| [..] |
| If no data is required for the command (only for regular mode, not for |
| Hyperbus mode), it is sent directly to the memory : |
| (+) In polling mode, the output of the function is done when the transfer is complete. |
| (+) In interrupt mode, HAL_OSPI_CmdCpltCallback() will be called when the transfer is complete. |
| [..] |
| For the indirect write mode, use HAL_OSPI_Transmit(), HAL_OSPI_Transmit_DMA() or |
| HAL_OSPI_Transmit_IT() after the command configuration : |
| (+) In polling mode, the output of the function is done when the transfer is complete. |
| (+) In interrupt mode, HAL_OSPI_FifoThresholdCallback() will be called when the fifo threshold |
| is reached and HAL_OSPI_TxCpltCallback() will be called when the transfer is complete. |
| (+) In DMA mode, HAL_OSPI_TxHalfCpltCallback() will be called at the half transfer and |
| HAL_OSPI_TxCpltCallback() will be called when the transfer is complete. |
| [..] |
| For the indirect read mode, use HAL_OSPI_Receive(), HAL_OSPI_Receive_DMA() or |
| HAL_OSPI_Receive_IT() after the command configuration : |
| (+) In polling mode, the output of the function is done when the transfer is complete. |
| (+) In interrupt mode, HAL_OSPI_FifoThresholdCallback() will be called when the fifo threshold |
| is reached and HAL_OSPI_RxCpltCallback() will be called when the transfer is complete. |
| (+) In DMA mode, HAL_OSPI_RxHalfCpltCallback() will be called at the half transfer and |
| HAL_OSPI_RxCpltCallback() will be called when the transfer is complete. |
| |
| *** Auto-polling functional mode *** |
| ==================================== |
| [..] |
| Configure the command sequence by the same way than the indirect mode |
| [..] |
| Configure the auto-polling functional mode using the HAL_OSPI_AutoPolling() |
| or HAL_OSPI_AutoPolling_IT() functions : |
| (+) The size of the status bytes, the match value, the mask used, the match mode (OR/AND), |
| the polling interval and the automatic stop activation. |
| [..] |
| After the configuration : |
| (+) In polling mode, the output of the function is done when the status match is reached. The |
| automatic stop is activated to avoid an infinite loop. |
| (+) In interrupt mode, HAL_OSPI_StatusMatchCallback() will be called each time the status match is reached. |
| |
| *** MDMA functional mode *** |
| ==================================== |
| [..] |
| Configure the SourceInc and DestinationInc of MDMA parameters in the HAL_OSPI_MspInit() function : |
| (+) MDMA settings for write operation : |
| (++) The DestinationInc should be MDMA_DEST_INC_DISABLE |
| (++) The SourceInc must be a value of @ref MDMA_Source_increment_mode (Except the MDMA_SRC_INC_DOUBLEWORD). |
| (++) The SourceDataSize must be a value of @ref MDMA Source data size (Except the MDMA_SRC_DATASIZE_DOUBLEWORD) |
| aligned with @ref MDMA_Source_increment_mode . |
| (++) The DestDataSize must be a value of @ref MDMA Destination data size (Except the MDMA_DEST_DATASIZE_DOUBLEWORD) |
| (+) MDMA settings for read operation : |
| (++) The SourceInc should be MDMA_SRC_INC_DISABLE |
| (++) The DestinationInc must be a value of @ref MDMA_Destination_increment_mode (Except the MDMA_DEST_INC_DOUBLEWORD). |
| (++) The SourceDataSize must be a value of @ref MDMA Source data size (Except the MDMA_SRC_DATASIZE_DOUBLEWORD) . |
| (++) The DestDataSize must be a value of @ref MDMA Destination data size (Except the MDMA_DEST_DATASIZE_DOUBLEWORD) |
| aligned with @ref MDMA_Destination_increment_mode. |
| (+) The buffer Transfer Length (BufferTransferLength) = number of bytes in the FIFO (FifoThreshold) of the Octospi. |
| [..] |
| In case of wrong MDMA setting |
| (+) For write operation : |
| (++) If the DestinationInc is different to MDMA_DEST_INC_DISABLE , it will be disabled by the HAL_OSPI_Transmit_DMA(). |
| (+) For read operation : |
| (++) If the SourceInc is not set to MDMA_SRC_INC_DISABLE , it will be disabled by the HAL_OSPI_Receive_DMA(). |
| |
| *** Memory-mapped functional mode *** |
| ===================================== |
| [..] |
| Configure the command sequence by the same way than the indirect mode except |
| for the operation type in regular mode : |
| (+) Operation type equals to read configuration : the command configuration |
| applies to read access in memory-mapped mode |
| (+) Operation type equals to write configuration : the command configuration |
| applies to write access in memory-mapped mode |
| (+) Both read and write configuration should be performed before activating |
| memory-mapped mode |
| [..] |
| Configure the memory-mapped functional mode using the HAL_OSPI_MemoryMapped() |
| functions : |
| (+) The timeout activation and the timeout period. |
| [..] |
| After the configuration, the OctoSPI will be used as soon as an access on the AHB is done on |
| the address range. HAL_OSPI_TimeOutCallback() will be called when the timeout expires. |
| |
| *** Errors management and abort functionality *** |
| ================================================= |
| [..] |
| HAL_OSPI_GetError() function gives the error raised during the last operation. |
| [..] |
| HAL_OSPI_Abort() and HAL_OSPI_AbortIT() functions aborts any on-going operation and |
| flushes the fifo : |
| (+) In polling mode, the output of the function is done when the transfer |
| complete bit is set and the busy bit cleared. |
| (+) In interrupt mode, HAL_OSPI_AbortCpltCallback() will be called when |
| the transfer complete bit is set. |
| |
| *** Control functions *** |
| ========================= |
| [..] |
| HAL_OSPI_GetState() function gives the current state of the HAL OctoSPI driver. |
| [..] |
| HAL_OSPI_SetTimeout() function configures the timeout value used in the driver. |
| [..] |
| HAL_OSPI_SetFifoThreshold() function configures the threshold on the Fifo of the OSPI Peripheral. |
| [..] |
| HAL_OSPI_GetFifoThreshold() function gives the current of the Fifo's threshold |
| |
| *** IO manager configuration functions *** |
| ========================================== |
| [..] |
| HAL_OSPIM_Config() function configures the IO manager for the OctoSPI instance. |
| |
| *** Callback registration *** |
| ============================================= |
| [..] |
| The compilation define USE_HAL_OSPI_REGISTER_CALLBACKS when set to 1 |
| allows the user to configure dynamically the driver callbacks. |
| |
| [..] |
| Use function HAL_OSPI_RegisterCallback() to register a user callback, |
| it allows to register following callbacks: |
| (+) ErrorCallback : callback when error occurs. |
| (+) AbortCpltCallback : callback when abort is completed. |
| (+) FifoThresholdCallback : callback when the fifo threshold is reached. |
| (+) CmdCpltCallback : callback when a command without data is completed. |
| (+) RxCpltCallback : callback when a reception transfer is completed. |
| (+) TxCpltCallback : callback when a transmission transfer is completed. |
| (+) RxHalfCpltCallback : callback when half of the reception transfer is completed. |
| (+) TxHalfCpltCallback : callback when half of the transmission transfer is completed. |
| (+) StatusMatchCallback : callback when a status match occurs. |
| (+) TimeOutCallback : callback when the timeout perioed expires. |
| (+) MspInitCallback : OSPI MspInit. |
| (+) MspDeInitCallback : OSPI MspDeInit. |
| [..] |
| This function takes as parameters the HAL peripheral handle, the Callback ID |
| and a pointer to the user callback function. |
| |
| [..] |
| Use function HAL_OSPI_UnRegisterCallback() to reset a callback to the default |
| weak (surcharged) function. It allows to reset following callbacks: |
| (+) ErrorCallback : callback when error occurs. |
| (+) AbortCpltCallback : callback when abort is completed. |
| (+) FifoThresholdCallback : callback when the fifo threshold is reached. |
| (+) CmdCpltCallback : callback when a command without data is completed. |
| (+) RxCpltCallback : callback when a reception transfer is completed. |
| (+) TxCpltCallback : callback when a transmission transfer is completed. |
| (+) RxHalfCpltCallback : callback when half of the reception transfer is completed. |
| (+) TxHalfCpltCallback : callback when half of the transmission transfer is completed. |
| (+) StatusMatchCallback : callback when a status match occurs. |
| (+) TimeOutCallback : callback when the timeout perioed expires. |
| (+) MspInitCallback : OSPI MspInit. |
| (+) MspDeInitCallback : OSPI MspDeInit. |
| [..] |
| This function) takes as parameters the HAL peripheral handle and the Callback ID. |
| |
| [..] |
| By default, after the HAL_OSPI_Init() and if the state is HAL_OSPI_STATE_RESET |
| all callbacks are reset to the corresponding legacy weak (surcharged) functions. |
| Exception done for MspInit and MspDeInit callbacks that are respectively |
| reset to the legacy weak (surcharged) functions in the HAL_OSPI_Init() |
| and HAL_OSPI_DeInit() only when these callbacks are null (not registered beforehand). |
| If not, MspInit or MspDeInit are not null, the HAL_OSPI_Init() and HAL_OSPI_DeInit() |
| keep and use the user MspInit/MspDeInit callbacks (registered beforehand) |
| |
| [..] |
| Callbacks can be registered/unregistered in READY state only. |
| Exception done for MspInit/MspDeInit callbacks that can be registered/unregistered |
| in READY or RESET state, thus registered (user) MspInit/DeInit callbacks can be used |
| during the Init/DeInit. |
| In that case first register the MspInit/MspDeInit user callbacks |
| using HAL_OSPI_RegisterCallback() before calling HAL_OSPI_DeInit() |
| or HAL_OSPI_Init() function. |
| |
| [..] |
| When The compilation define USE_HAL_OSPI_REGISTER_CALLBACKS is set to 0 or |
| not defined, the callback registering feature is not available |
| and weak (surcharged) callbacks are used. |
