##### 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 using 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.
|
|
|
|
*** 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 (overridden) 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 (overridden) functions.
|
|
Exception done for MspInit and MspDeInit callbacks that are respectively
|
|
reset to the legacy weak (overridden) 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 (overridden) callbacks are used.
