SDIO on STM32F3-Discovery

 Just wondering if anyone has a working implementation on the STM32-F3Discovey of SPI access to a SD card? I'm using stm32303c_eval_spi_sd.c and stm32303c_eval_spi_sd.h from

STM32F30x_DSP_StdPeriph_Lib_V1.0.0/Utilities/STM32_EVAL/STM32303C_EVAL/,the low-level routines SD_LowLevel_DeInit() and SD_LowLevel_Init() from STM32F30x_DSP_StdPeriph_Lib_V1.0.0/Utilities/STM32_EVAL/STM32303C_EVAL/stm32303c_eval.cand the SD SPI Interface pin assignment below, but get a timeout when it activates the card initialization process.Any pointers to code and/or help is much appreciated.&sharpdefine SD_SPI                           SPI2&sharpdefine SD_SPI_CLK                       RCC_APB1Periph_SPI2&sharpdefine SD_CS_PIN                        GPIO_Pin_12                 /* PB.12 */&sharpdefine SD_CS_GPIO_PORT                  GPIOB                       /* GPIOB */&sharpdefine SD_CS_GPIO_CLK                   RCC_AHBPeriph_GPIOB&sharpdefine SD_SPI_SCK_PIN                   GPIO_Pin_13                 /* PB.13 */&sharpdefine SD_SPI_SCK_GPIO_PORT             GPIOB                       /* GPIOB */&sharpdefine SD_SPI_SCK_GPIO_CLK              RCC_AHBPeriph_GPIOB&sharpdefine SD_SPI_SCK_SOURCE                GPIO_PinSource13&sharpdefine SD_SPI_SCK_AF                    GPIO_AF_5&sharpdefine SD_SPI_MISO_PIN                  GPIO_Pin_14                  /* PB.14 */&sharpdefine SD_SPI_MISO_GPIO_PORT            GPIOB                       /* GPIOB */&sharpdefine SD_SPI_MISO_GPIO_CLK             RCC_AHBPeriph_GPIOB&sharpdefine SD_SPI_MISO_SOURCE               GPIO_PinSource14&sharpdefine SD_SPI_MISO_AF                   GPIO_AF_5&sharpdefine SD_SPI_MOSI_PIN                  GPIO_Pin_15                  /* PB.15 */&sharpdefine SD_SPI_MOSI_GPIO_PORT            GPIOB                       /* GPIOB */&sharpdefine SD_SPI_MOSI_GPIO_CLK             RCC_AHBPeriph_GPIOB&sharpdefine SD_SPI_MOSI_SOURCE               GPIO_PinSource15&sharpdefine SD_SPI_MOSI_AF                   GPIO_AF_5&sharpdefine SD_DETECT_PIN                    GPIO_Pin_6                 /* PC.06 */&sharpdefine SD_DETECT_EXTI_LINE              EXTI_Line6&sharpdefine SD_DETECT_EXTI_PIN_SOURCE        EXTI_PinSource6&sharpdefine SD_DETECT_GPIO_PORT              GPIOC                       /* GPIOC */&sharpdefine SD_DETECT_GPIO_CLK               RCC_AHBPeriph_GPIOC&sharpdefine SD_DETECT_EXTI_PORT_SOURCE       EXTI_PortSourceGPIOC&sharpdefine SD_DETECT_EXTI_IRQn              EXTI9_5_IRQn #stm32f3discovery #spi-sd-card-stm32-discovery #stm32

The chip select needs a pull-up (10K).

Not clear if the software supports SD or SDHC cards, but doesn't look to support cards >=4GB properly, so I'd guess is SD only with cards of 2GB or less.

Has anyone modified the SPI SD library to support a 4GB card?

Perhaps not the exact scenario, but Yes

Is the updated library to handle 4GB and larger SD cards available to download? I have downloaded the  stm32303c_eval_sp_sd.c & .h and it assumes that you have a 2GB or smaller card.
