integer.h Integer type definitions for FatFs.
option Optional external modules.
Low level disk I/O module is not included in this archive because the FatFs
module is only a generic file system layer and it does not depend on any specific
storage device. You have to provide a low level disk I/O module written to
control the storage device that attached to the target system.

### V2.1.1/25-01-2019 ###
============================
+ sd_diskio_dma_rtos_template.c
- Fix memory leak in the SD_Initialize()
- Disable the ENABLE_SD_DMA_CACHE_MAINTENANCE flag by default to fix a build error for CM4

### V2.1.0/21-09-2018 ###
============================
+ ff.c
- back-port a fix from 0.13, to correct an issue when using multi-threading
access in the same device due to a missing semaphore lock when calling
disk_status() API.
+ sd_diskio_dma_rtos_template.c
- Add support to CMSIS-RTOS V2 API
+ sd_diskio_dma_rtos_template.c sd_diskio_dma_template.c

### V2.0.2/17-November-2017 ###
============================
+ sdram_diskio_template.c sram_diskio_template.c
Fix wrong buffer size in the (SRAM/SDRAM)DISK_read(), (SRAM/SDRAM)DISK_write()
+ sd_diskio_template.c
- define a generic 'SD_TIMEOUT' based on the BSP drivers defines. This fixes
a build issue when using this driver with the Adafruit shield.
+ sd_diskio_dma_rtos_template.c
- add a check via osKernelRunning(), to avoid runtime errors due to
osMessageXXX calls that needs the "osKernelStart()" call done first.
+ sd_diskio_dma_template.c, sd_diskio_dma_rtos_template.c
- fix wrong address alignment when calling SCB_InvalidateDCache_by_Addr() and
SCB_CleanDCache_by_Addr(), the address has to be 32-Byte and not
32-bit aligned.
- fix BSP_SD_ReadCpltCallback() and BSP_SD_WriteCpltCallback() prototypes by
adding 'void' as argument to avoid IAR compiler errors
+ sd_diskio_template.c sd_diskio_dma_template.c, sd_diskio_dma_rtos_template.c
- add the flag "DISABLE_SD_INIT" to give the user the choice to initialize the SD
either in the application or in the FatFs diskio driver.
+ all xxx_diskio_template.c
- fix GET_BLOCK_SIZE ioctl call; the return value is in unit of sectors.
### V2.0.1/10-July-2017 ###
============================
+ sd_diskio_dma_template.c, sd_diskio_dma_rtos_template.c
- add the flag "ENABLE_SD_DMA_CACHE_MAINTENANCE", to enable cache maintenance at each read write operation.
This is useful for STM32F7/STM32H7 based platforms when using a cachable memory region.
- add timeout checks in SD_Read() and SD_Write() to give the control back to the application to decide in case of errors.
+ ff_gen_drv.c: fix a wrong check that causes an out of bound array access.
### V2.0.0/07-March-2017 ###
============================
+ Upgrade to use FatFS R0.12c. The R0.12c breaks the API compatibility with R0.11b.
- f_mkfs() API has a new signature.
- The _CODE_PAGE got new values.
- For more details check the files (doc/updates.txt) and the following urls:
http://elm-chan.org/fsw/ff/en/mkfs.html
http://elm-chan.org/fsw/ff/en/config.html
+ Add USB, RAMDISK and uSD template drivers under src/drivers.
- The diskio drivers aren't part of fatfs anymore, they are just templates instead.
- User has to copy the suitable template .c/.h file under the project, rename them by
removing the "_template" suffix then link them into the final application.
- The diskio driver .c/.h files have to be edited according to the used platform.
+ Define the macros "ff_malloc" and "ff_free" in the ff_conf_template.h and use
them in the syscall.c instead of direct calls to stdlib malloc and free functions.
+ Define the "__weak" attribute in diskio.c for the GNU GCC compiler
### V1.4.0/09-September-2016 ###
================================
+ Upgrade to use FatFs R0.12b.
+ ff_conf.h: remove the use of define "_USE_BUFF_WO_ALIGNMENT".
### V1.3.0/08-May-2015 ###
==========================
+ Upgrade to use FatFs R0.11.
+ Add new APIs FATFS_LinkDriverEx() and FATFS_UnLinkDriverEx() to manage USB Key Disk having
multi-lun capability. These APIs are equivalent to FATFS_LinkDriver() and FATFS_UnLinkDriver()
with "lun" parameter set to 0.
+ ff_conf.h: add new define "_USE_BUFF_WO_ALIGNMENT".
This option is available only for usbh diskio interface and allow to disable
the management of the unaligned buffer.
When STM32 USB OTG HS or FS IP is used with internal DMA enabled, this define
must be set to 0 to align data into 32bits through an internal scratch buffer
before being processed by the DMA . Otherwise (DMA not used), this define must
be set to 1 to avoid Data alignment and improve the performance.
Please note that if _USE_BUFF_WO_ALIGNMENT is set to 1 and an unaligned 32bits
buffer is forwarded to the FatFs Write/Read functions, an error will be returned.
(0: default value or 1: unaligned buffer return an error).
+ Important note:
For application code based on previous FatFs version; when moving to R0.11
the changes that need to be done is to update ffconf.h file, taking
ffconf_template.h file as reference.
### V1.2.1/20-November-2014 ###
===============================
+ Disk I/O drivers; change count argument type from BYTE to UINT
+ Important note:
For application code based on previous FatFs version; when moving to R0.10b
the only change that need to be done is to update ffconf.h file, taking
ffconf_template.h file as reference.
### V1.2.0/04-November-2014 ###
===============================
+ Upgrade to use FatFs R0.10b.
+ diskio.c: update disk_read() and disk_write() argument's type.
+ Important note:
For application code based on previous FatFs version; when moving to R0.10b
the only change that need to be done is to update ffconf.h file, taking
ffconf_template.h file as reference.
### V1.1.1/12-September-2014 ###
================================
+ ff_gen_drv.c: Update the Disk_drvTypeDef disk variable initialization to avoid
warnings detected with Atollic TrueSTUDIO Complier.
### V1.1.0/22-April-2014 ###
============================
+ Update sd_diskio to use SD BSP in polling mode instead of DMA mode (the scratch
buffer needed for DMA alignment is removed as well).
+ diskio.c and ff_gen_drv.c/.h: update to prevent multiple initialization.
### V1.0.0/18-February-2014 ###
===============================
+ First R0.10 customized version for STM32Cube solution.

/**
* An event group is a collection of bits to which an application can assign a
* meaning. For example, an application may create an event group to convey
* the status of various CAN bus related events in which bit 0 might mean "A CAN
* message has been received and is ready for processing", bit 1 might mean "The
* application has queued a message that is ready for sending onto the CAN
* network", and bit 2 might mean "It is time to send a SYNC message onto the
* CAN network" etc. A task can then test the bit values to see which events
* are active, and optionally enter the Blocked state to wait for a specified
* bit or a group of specified bits to be active. To continue the CAN bus
* example, a CAN controlling task can enter the Blocked state (and therefore
* not consume any processing time) until either bit 0, bit 1 or bit 2 are
* active, at which time the bit that was actually active would inform the task
* which action it had to take (process a received message, send a message, or
* send a SYNC).
*
* The event groups implementation contains intelligence to avoid race
* conditions that would otherwise occur were an application to use a simple
* variable for the same purpose. This is particularly important with respect
* to when a bit within an event group is to be cleared, and when bits have to
* be set and then tested atomically - as is the case where event groups are
* used to create a synchronisation point between multiple tasks (a
* 'rendezvous').

* This is the list implementation used by the scheduler. While it is tailored
* heavily for the schedulers needs, it is also available for use by
* application code.
*
* list_ts can only store pointers to list_item_ts. Each ListItem_t contains a
* numeric value (xItemValue). Most of the time the lists are sorted in
* descending item value order.
*
* Lists are created already containing one list item. The value of this
* item is the maximum possible that can be stored, it is therefore always at
* the end of the list and acts as a marker. The list member pxHead always
* points to this marker - even though it is at the tail of the list. This
* is because the tail contains a wrap back pointer to the true head of
* the list.
*
* In addition to it's value, each list item contains a pointer to the next
* item in the list (pxNext), a pointer to the list it is in (pxContainer)
* and a pointer to back to the object that contains it. These later two
* pointers are included for efficiency of list manipulation. There is
* effectively a two way link between the object containing the list item and
* the list item itself.

* Message buffers build functionality on top of FreeRTOS stream buffers.
* Whereas stream buffers are used to send a continuous stream of data from one
* task or interrupt to another, message buffers are used to send variable
* length discrete messages from one task or interrupt to another. Their
* implementation is light weight, making them particularly suited for interrupt
* to task and core to core communication scenarios.
*
* ***NOTE***: Uniquely among FreeRTOS objects, the stream buffer
* implementation (so also the message buffer implementation, as message buffers
* are built on top of stream buffers) assumes there is only one task or
* interrupt that will write to the buffer (the writer), and only one task or
* interrupt that will read from the buffer (the reader). It is safe for the
* writer and reader to be different tasks or interrupts, but, unlike other
* FreeRTOS objects, it is not safe to have multiple different writers or
* multiple different readers. If there are to be multiple different writers
* then the application writer must place each call to a writing API function
* (such as xMessageBufferSend()) inside a critical section and set the send
* block time to 0. Likewise, if there are to be multiple different readers
* then the application writer must place each call to a reading API function
* (such as xMessageBufferRead()) inside a critical section and set the receive
* timeout to 0.
*
* Message buffers hold variable length messages. To enable that, when a
* message is written to the message buffer an additional sizeof( size_t ) bytes
* are also written to store the message's length (that happens internally, with
* the API function). sizeof( size_t ) is typically 4 bytes on a 32-bit
* architecture, so writing a 10 byte message to a message buffer on a 32-bit
* architecture will actually reduce the available space in the message buffer
* by 14 bytes (10 byte are used by the message, and 4 bytes to hold the length
* of the message).

*
* Receives bytes from a stream buffer.
*
* ***NOTE***: Uniquely among FreeRTOS objects, the stream buffer
* implementation (so also the message buffer implementation, as message buffers
* are built on top of stream buffers) assumes there is only one task or
* interrupt that will write to the buffer (the writer), and only one task or
* interrupt that will read from the buffer (the reader). It is safe for the
* writer and reader to be different tasks or interrupts, but, unlike other
* FreeRTOS objects, it is not safe to have multiple different writers or
* multiple different readers. If there are to be multiple different writers
* then the application writer must place each call to a writing API function
* (such as xStreamBufferSend()) inside a critical section and set the send
* block time to 0. Likewise, if there are to be multiple different readers
* then the application writer must place each call to a reading API function
* (such as xStreamBufferRead()) inside a critical section and set the receive
* block time to 0.
*
* Use xStreamBufferReceive() to read from a stream buffer from a task. Use
* xStreamBufferReceiveFromISR() to read from a stream buffer from an
* interrupt service routine (ISR).
*
* @param xStreamBuffer The handle of the stream buffer from which bytes are to
* be received.
*
* @param pvRxData A pointer to the buffer into which the received bytes will be
* copied.
*
* @param xBufferLengthBytes The length of the buffer pointed to by the
* pvRxData parameter. This sets the maximum number of bytes to receive in one
* call. xStreamBufferReceive will return as many bytes as possible up to a
* maximum set by xBufferLengthBytes.
*
* @param xTicksToWait The maximum amount of time the task should remain in the
* Blocked state to wait for data to become available if the stream buffer is
* empty. xStreamBufferReceive() will return immediately if xTicksToWait is
* zero. The block time is specified in tick periods, so the absolute time it
* represents is dependent on the tick frequency. The macro pdMS_TO_TICKS() can
* be used to convert a time specified in milliseconds into a time specified in
* ticks. Setting xTicksToWait to portMAX_DELAY will cause the task to wait
* indefinitely (without timing out), provided INCLUDE_vTaskSuspend is set to 1
* in FreeRTOSConfig.h. A task does not use any CPU time when it is in the
* Blocked state.
*
* @return The number of bytes actually read from the stream buffer, which will
* be less than xBufferLengthBytes if the call to xStreamBufferReceive() timed
* out before xBufferLengthBytes were available.

*
* @param pxHigherPriorityTaskWoken It is possible that a stream buffer will
* have a task blocked on it waiting for space to become available. Calling
* xStreamBufferReceiveFromISR() can make space available, and so cause a task
* that is waiting for space to leave the Blocked state. If calling
* xStreamBufferReceiveFromISR() causes a task to leave the Blocked state, and

* (the task that was interrupted), then, internally,
* xStreamBufferReceiveFromISR() will set *pxHigherPriorityTaskWoken to pdTRUE.
* If xStreamBufferReceiveFromISR() sets this value to pdTRUE, then normally a
* context switch should be performed before the interrupt is exited. That will
* ensure the interrupt returns directly to the highest priority Ready state
* task. *pxHigherPriorityTaskWoken should be set to pdFALSE before it is

https://www.freertos.org/a00110.html#configASSERT
1) Stack overflow -
see https://www.freertos.org/Stacks-and-stack-overflow-checking.html
2) Incorrect interrupt priority assignment, especially on Cortex-M
parts where numerically high priority values denote low actual
interrupt priorities, which can seem counter intuitive. See
https://www.freertos.org/RTOS-Cortex-M3-M4.html and the definition
of configMAX_SYSCALL_INTERRUPT_PRIORITY on
https://www.freertos.org/a00110.html
3) Calling an API function from within a critical section or when
the scheduler is suspended, or calling an API function that does
not end in "FromISR" from an interrupt.
4) Using a queue or semaphore before it has been initialised or
before the scheduler has been started (are interrupts firing
before vTaskStartScheduler() has been called?).

the interrupt's sub-priority. For simplicity all bits must be defined
to be pre-emption priority bits. The following assertion will fail if
this is not the case (if some bits represent a sub-priority).
If the application only uses CMSIS libraries for interrupt
configuration then the correct setting can be achieved on all Cortex-M
devices by calling NVIC_SetPriorityGrouping( 0 ); before starting the
scheduler. Note however that some vendor specific peripheral libraries
assume a non-zero priority group setting, in which cases using a value
of zero will result in unpredictable behaviour. */

/*
* A sample implementation of pvPortMalloc() that allows the heap to be defined
* across multiple non-contigous blocks and combines (coalescences) adjacent
* memory blocks as they are freed.
*
* See heap_1.c, heap_2.c, heap_3.c and heap_4.c for alternative
* implementations, and the memory management pages of http://www.FreeRTOS.org
* for more information.
*
* Usage notes:
*
* vPortDefineHeapRegions() ***must*** be called before pvPortMalloc().
* pvPortMalloc() will be called if any task objects (tasks, queues, event
* groups, etc.) are created, therefore vPortDefineHeapRegions() ***must*** be
* called before any other objects are defined.
*
* vPortDefineHeapRegions() takes a single parameter. The parameter is an array
* of HeapRegion_t structures. HeapRegion_t is defined in portable.h as
*
* typedef struct HeapRegion
* {
* uint8_t *pucStartAddress; << Start address of a block of memory that will be part of the heap.
* size_t xSizeInBytes; << Size of the block of memory.
* } HeapRegion_t;
*
* The array is terminated using a NULL zero sized region definition, and the
* memory regions defined in the array ***must*** appear in address order from
* low address to high address. So the following is a valid example of how
* to use the function.
*
* HeapRegion_t xHeapRegions[] =
* {
* { ( uint8_t * ) 0x80000000UL, 0x10000 }, << Defines a block of 0x10000 bytes starting at address 0x80000000
* { ( uint8_t * ) 0x90000000UL, 0xa0000 }, << Defines a block of 0xa0000 bytes starting at address of 0x90000000
* { NULL, 0 } << Terminates the array.
* };
*
* vPortDefineHeapRegions( xHeapRegions ); << Pass the array into vPortDefineHeapRegions().
*
* Note 0x80000000 is the lower address so appears in the array first.

Each real time kernel port consists of three files that contain the core kernel
components and are common to every port, and one or more files that are
specific to a particular microcontroller and or compiler.
+ The FreeRTOS/Source directory contains the three files that are common to
every port - list.c, queue.c and tasks.c. The kernel is contained within these
three files. croutine.c implements the optional co-routine functionality - which
is normally only used on very memory limited systems.
+ The FreeRTOS/Source/Portable directory contains the files that are specific to
a particular microcontroller and or compiler.

=======================
The purpose of this release is to Upgrade to use FreeRTOS V8.2.3.
It also provides fixes for minor issues.
+ cmsis_os.c
- Implementation of functions "osSignalSet" and "osSignalWait" are now delimited by
#define configUSE_TASK_NOTIFICATIONS.
- Function "osTimerStart" : fix for an assert issue when called from an ISR.
- Function "osMailCreate" : internal variables initialization.
- Function "osSignalWait" : signals value is now compared versus integer zero for error checking.
+ freeRTOS sources
- FreeRTOS.h file : Add configuration sanity check in case of configUSE_RECURSIVE_MUTEXES set
and configUSE_MUTEXES not set.
+ STMicroelectronics license simplifications, see license disclaimer within this file's header
### 27-March-2015 ###
=====================
The purpose of this release is to Upgrade to use FreeRTOS V8.2.1.
+ Major change of the version 8.2.1 is the support of CM7 core.
For STM32F746xx/STM32F756xx devices, need to use port files under Source/Portable/XXX/ARM_CM7/r0p1,
where XXX refers to the compiler used.
+ It also provides implementation of osSignal management APIs, osSignalSet() and osSignalWait(),
fixes osMassage queue size, osMailQDef macro and osDelayUntil parameters.
+ In this release an alignment has been done in ARM_CM4 and ARM_CM3 port.c versus ARM_CM0 port.c
regarding the use of macros configPRE_SLEEP_PROCESSING and configPOST_SLEEP_PROCESSING, these tow macros
are now taking as parameter as pointer to TickType_t.
+ cmsis_os.c
- Add implementation of osSignalSet() and osSignalWait() APIs
- Fix massage queue size in osMessageCreate API
- osDelayUntil: parameter PreviousWakeTime is now passed as a pointer.
- Enabling Mail queue management APIs (temporary removed in previous version).
- Function "osThreadGetPriority" uses now uxTaskPriorityGetFromISR if called from an interrupt handler, if not use uxTaskPriorityGet.
+ cmsis_os.h
- osFeature_Wait is defined to 0 to indicate that osWait function is not available (as specified by cmsis_os template by ARM)
- Fix compilation issue with osMailQDef macro.
- Enabling Mail queue management APIs (temporary removed in previous version)
+ freeRTOS sources
- ARM_CM3 port.c and ARM_CM4 port.c:
function vPortSuppressTicksAndSleep : configPRE_SLEEP_PROCESSING and configPOST_SLEEP_PROCESSING are now taking
as parameter as pointer to TickType_t.
The purpose of this change is to align the CM3 and CM4 implementation with CM0 one.
+ Note
- osSignalSet returns an int32_t value which is a a status (osOK or osError)
instead of the previous signal value as specified in cmsis_os template by ARM.
This is mainly due to freeRTOS implementation, the return value will be aligned (with the cmsis os template by ARM) as soon as the freeRTOS next version will allow it.
- osThreadDef() macro is defined in the freeRTOS cmsis_os.h wrapper as follow :
osThreadDef(name, thread, priority, instances, stacksz)
the macro osThreadDef() as defined in ARM cmsis_os.h is defined with 4 parameters :
name : name of the thread function.
priority : initial priority of the thread function.
instances : number of possible thread instances.
stacksz : stack size (in bytes) requirements for the thread function.
- osThreadDef as defined in the ARM template file cmsis_os.h assumes that the thread name is the same as the thread function name.
where the freeRTOS implementation gives separate parameters for the thread name and the thread function name.
care must be taken when porting an application from/to another OS to/from freeRTOS cmsis_os regarding this macro.
the macro osThreadDef() as defined in ARM cmsis_os.h template is defined with 4 parameters :
name : name of the thread function.
priority : initial priority of the thread function.
instances : number of possible thread instances.
stacksz : stack size (in bytes) requirements for the thread function.
the macro osThreadDef() as defined in freeRTOS cmsis_os.h is defined with 5 parameters :
name : name of the thread (used for debugging and trace).
thread : name of the thread function
priority : initial priority of the thread function.
instances : number of possible thread instances.
stacksz : stack size (in bytes) requirements for the thread function.
### 25-December-2014 ###
========================
The purpose of this release is to remove compilation errors and warning. It also reintroduces
the function osThreadIsSuspended() which has been removed in the version V1.2.0.
+ cmsis_os.c
- osThreadGetPriority() and makeCmsisPriority(): replace INCLUDE_vTaskPriorityGet by the correct
freeRTOS constant uxTaskPriorityGet.
The version 1.2.2 is using a wrong constant INCLUDE_vTaskPriorityGet, while the correct freeRTOS
constant is uxTaskPriorityGet.
This fix ensure a safe use of osThreadGetPriority() function.
- osThreadIsSuspended(): this function has been removed in version V1.2.0, it is now available gain.
User can either use this function to check if a Thread is suspended either use function osThreadGetState,
which is more generic, to check the exact state of a thread.
- osThreadList(): this function is now taking as argument a pointer to uint8_t instead of a pointer to int8_t.
The change is made to remove a compilation warning.
- osRecursiveMutexCreate(): the prototype has been changed to osMutexId osRecursiveMutexCreate (const osMutexDef_t *mutex_def)
This change is made to make osRecursiveMutexCreate() compatible with function MutexCreate().
It also allow the better use of the function in conjunction with the macro osMutex, note that osMutex return a
"const osMutexDef_t *mutex_def".
example : osMutex1Id = osRecursiveMutexCreate (osMutex(Mutex1));
- Fix implementation of functions osSemaphoreWait(), osMutexRelease() and osMutexWait() by using the appropriate
freeRTOS “FromISR” APIs when called from an interrupt.
- Fix compilation warning when the constant INCLUDE_eTaskGetState is not defined
+ cmsis_os.h
- osThreadIsSuspended(): add function prototype.
- osThreadList(): function prototype modified as described in cmsis_os.c section.
- osRecursiveMutexCreate(): function modified as described in cmsis_os.c section.
+ Important note:
Mail Queue Management Functions are not supported in this cmsis_os version, will be added in the next release.
### 04-December-2014 ###
========================
+ cmsis_os.c, osSemaphoreCreate(): use vSemaphoreCreateBinary() instead of xSemaphoreCreateBinary(),
to keep compatibility with application code developed on FreeRTOS V7.6.0.
### 07-November-2014 ###
========================
+ cmsis_os.h: modify the osThreadState enum to fix warning generated by ARMCC compiler
+ task.c: add preprocessor compilation condition for prvTaskIsTaskSuspended() function
(it's build only when INCLUDE_vTaskSuspend option is enabled in FreeRTOSConfig.h file)
### 04-November-2014 ###
========================
+ Upgrade to use FreeRTOS V8.1.2 and CMSIS-RTOS V1.02.
+ cmsis_os.c
- Almost of CMSIS-RTOS APIs are implemented for FreeRTOS
- Additional wrapper APIs created for FreeRTOS
+ Important note:
When upgrading existing application code to use this last version, the following
update should be considered:
- osThreadIsSuspended() is no longer public API in FreeRTOS and it should
be replaced by the wrapping of eTaskGetState()
- osKernelStart() API changed, must be updated
- update FreeRTOSConfig.h file, taking FreeRTOSConfig_template.h file as reference
### 13-June-2014 ###
====================
+ FreeRTOSConfig_template.h: add this definition #define INCLUDE_xTaskGetSchedulerState 1
to enable the use of xTaskGetSchedulerState() API in the
application code.
### 30-April-2014 ###
=====================
+ cmsis_os.c: add preprocessor compilation condition when calling some FreeRTOS APIs, to avoid link
errors with MDK-ARM when some FreeRTOS features are not enabled in FreeRTOSConfig.h
### 22-April-2014 ###
=====================
+ Add Tickles mode for CM0 port (IAR, GCC, RVDS).
### 18-February-2014 ###
========================
+ FreeRTOS V7.6.0 customized version for STM32Cube solution.
