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 applicatio
