+ * @file stm324x9i_eval_sdio_sd.c
+ * @author MCD Application Team
+ * @version V1.0.3
+ * @date 13-November-2013
+ * @brief This file provides a set of functions needed to manage the SDIO SD
+ * Card memory mounted on STM324x9I-EVAL evaluation board.
+ *
+ *
+ * @verbatim
+ *
+ * ===================================================================
+ * How to use this driver
+ * ===================================================================
+ * It implements a high level communication layer for read and write
+ * from/to this memory. The needed STM32 hardware resources (SDIO and
+ * GPIO) are defined in stm324x9i_eval.h file, and the initialization is
+ * performed in SD_LowLevel_Init() function declared in stm324x9i_eval.c
+ * file.
+ * You can easily tailor this driver to any other development board,
+ * by just adapting the defines for hardware resources and
+ * SD_LowLevel_Init() function.
+ *
+ * A - SD Card Initialization and configuration
+ * ============================================
+ * - To initialize the SD Card, use the SD_Init() function. It
+ * Initializes the SD Card and put it into StandBy State (Ready
+ * for data transfer). This function provides the following operations:
+ *
+ * 1 - Apply the SD Card initialization process at 400KHz and check
+ * the SD Card type (Standard Capacity or High Capacity). You
+ * can change or adapt this frequency by adjusting the
+ * "SDIO_INIT_CLK_DIV" define inside the stm324x9i_eval.h file.
+ * The SD Card frequency (SDIO_CK) is computed as follows:
+ *
+ * +---------------------------------------------+
+ * | SDIO_CK = SDIOCLK / (SDIO_INIT_CLK_DIV + 2) |
+ * +---------------------------------------------+
+ *
+ * In initialization mode and according to the SD Card standard,
+ * make sure that the SDIO_CK frequency doesn't exceed 400KHz.
+ *
+ * 2 - Get the SD CID and CSD data. All these information are
+ * managed by the SDCardInfo structure. This structure provides
+ * also ready computed SD Card capacity and Block size.
+ *
+ * 3 - Configure the SD Card Data transfer frequency. By Default,
+ * the card transfer frequency is set to 24MHz. You can change
+ * or adapt this frequency by adjusting the "SDIO_TRANSFER_CLK_DIV"
+ * define inside the stm324x9i_eval.h file.
+ * The SD Card frequency (SDIO_CK) is computed as follows:
+ *
+ * +---------------------------------------------+
+ * | SDIO_CK = SDIOCLK / (SDIO_INIT_CLK_DIV + 2) |
+ * +---------------------------------------------+
+ *
+ * In transfer mode and according to the SD Card standard,
+ * make sure that the SDIO_CK frequency doesn't exceed 25MHz
+ * and 50MHz in High-speed mode switch.
+ * To be able to use a frequency higher than 24MHz, you should
+ * use the SDIO peripheral in bypass mode. Refer to the
+ * corresponding reference manual for more details.
+ *
+ * 4 - Select the corresponding SD Card according to the address
+ * read with the step 2.
+ *
+ * 5 - Configure the SD Card in wide bus mode: 4-bits data.
+ *
+ * B - SD Card Read operation
+ * ==========================
+ * - You can read SD card by using two functions : SD_ReadBlock() and
+ * SD_ReadMultiBlocks() functions. These functions support only
+ * 512-byte block length.
+ * - The SD_ReadBlock() function reads only one block (512-byte). This
+ * function can transfer the data using DMA controller or using
+ * polling mode. To select between DMA or polling mode refer to
+ * "SD_DMA_MODE" or "SD_POLLING_MODE" inside the stm324x9i_eval_sdio_sd.h
+ * file and uncomment the corresponding line. By default the SD DMA
+ * mode is selected
+ * - The SD_ReadMultiBlocks() function reads only mutli blocks (multiple
+ * of 512-byte).
+ * - Any read operation should be followed by two functions to check
+ * if the DMA Controller and SD Card status.
+ * - SD_ReadWaitOperation(): this function insure that the DMA
+ * controller has finished all data transfer.
+ * - SD_GetStatus(): to check that the SD Card has finished the
+ * data transfer and it is ready for data.
+ *
+ * - The DMA transfer is finished by the SDIO Data End interrupt.
+ * User has to call the SD_ProcessIRQ() function inside the SDIO_IRQHandler()
+ * and SD_ProcessDMAIRQ() function inside the DMA2_Streamx_IRQHandler().
+ * Don't forget to enable the SDIO_IRQn and DMA2_Stream3_IRQn or
+ * DMA2_Stream6_IRQn interrupts using the NVIC controller.
+ *
+ * C - SD Card Write operation
+ * ===========================
+ * - You can write SD card by using two function: SD_WriteBlock() and
+ * SD_WriteMultiBlocks() functions. These functions support only
+ * 512-byte block length.
+ * - The SD_WriteBlock() function write only one block (512-byte). This
+ * function can transfer the data using DMA controller or using
+ * polling mode. To select between DMA or polling mode refer to
+ * "SD_DMA_MODE" or "SD_POLLING_MODE" inside the stm324x9i_eval_sdio_sd.h
+ * file and uncomment the corresponding line. By default the SD DMA
+ * mode is selected
+ * - The SD_WriteMultiBlocks() function write only mutli blocks (multiple
+ * of 512-byte).
+ * - Any write operation should be followed by two functions to check
+ * if the DMA Controller and SD Card status.
+ * - SD_ReadWaitOperation(): this function insure that the DMA
+ * controller has finished all data transfer.
+ * - SD_GetStatus(): to check that the SD Card has finished the
+ * data transfer and it is ready for data.
+ *
+ * - The DMA transfer is finished by the SDIO Data End interrupt.
+ * User has to call the SD_ProcessIRQ() function inside the SDIO_IRQHandler()
+ * and SD_ProcessDMAIRQ() function inside the DMA2_Streamx_IRQHandler().
+ * Don't forget to enable the SDIO_IRQn and DMA2_Stream3_IRQn or
+ * DMA2_Stream6_IRQn interrupts using the NVIC controller.
+ *
+ *
+ * D - SD card status
+ * ==================
+ * - At any time, you can check the SD Card status and get the SD card
+ * state by using the SD_GetStatus() function. This function checks
+ * first if the SD card is still connected and then get the internal
+ * SD Card transfer state.
+ * - You can also get the SD card SD Status register by using the
+ * SD_SendSDStatus() function.
+ *
+ * E - Programming Model (Selecting DMA for SDIO data Transfer)
+ * ============================================================
+ * Status = SD_Init(); // Initialization Step as described in section A
+ *
+ * // SDIO Interrupt ENABLE
+ * NVIC_InitStructure.NVIC_IRQChannel = SDIO_IRQn;
+ * NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;
+ * NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;
+ * NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
+ * NVIC_Init(&NVIC_InitStructure);
+ * // DMA2 STREAMx Interrupt ENABLE
+ * NVIC_InitStructure.NVIC_IRQChannel = SD_SDIO_DMA_IRQn;
+ * NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 1;
+ * NVIC_Init(&NVIC_InitStructure);
+ *
+ * // Write operation as described in Section C
+ * Status = SD_WriteBlock(buffer, address, 512);
+ * Status = SD_WaitWriteOperation();
+ * while(SD_GetStatus() != SD_TRANSFER_OK);
+ *
+ * Status = SD_WriteMultiBlocks(buffer, address, 512, NUMBEROFBLOCKS);
+ * Status = SD_WaitWriteOperation();
+ * while(SD_GetStatus() != SD_TRANSFER_OK);
+ *
+ * // Read operation as described in Section B
+ * Status = SD_ReadBlock(buffer, address, 512);
+ * Status = SD_WaitReadOperation();
+ * while(SD_GetStatus() != SD_TRANSFER_OK);
+ *
+ * Status = SD_ReadMultiBlocks(buffer, address, 512, NUMBEROFBLOCKS);
+ * Status = SD_WaitReadOperation();
+ * while(SD_GetStatus() != SD_TRANSFER_OK);
+ *
+ * - Add the SDIO and DMA2 StreamX (3 or 6) IRQ Handlers:
+ * void SDIO_IRQHandler(void)
+ * {
+ * SD_ProcessIRQ();
+ * }
+ * void SD_SDIO_DMA_IRQHANDLER(void)
+ * {
+ * SD_ProcessDMAIRQ();
+ * }
+ *
+ * F - Programming Model (Selecting Polling for SDIO data Transfer)
+ * ================================================================
+ * //Only SD Card Single Block operation are managed.
+ * Status = SD_Init(); // Initialization Step as described in section
+ *
+ * // Write operation as described in Section C
+ * Status = SD_WriteBlock(buffer, address, 512);
+ *
+ * // Read operation as described in Section B
+ * Status = SD_ReadBlock(buffer, address, 512);
