SPI3 on MCBSTM3 not working

I'm trying to get SPI3 working on the MCBSTM32C board from keil, but without result. I've remapped the pins because the display uses them. I am not getting anything on any pin. Here is my configuration. Anyone have an idea what could be the problem?

void sFLASH_Init(void)
{
  SPI_InitTypeDef  SPI_InitStructure;


  FLASH_LowLevel_Init();

  /*!< Deselect the FLASH: Chip Select high */
  sFLASH_CS_HIGH();


  /*!< SPI configuration */
  SPI_InitStructure.SPI_Direction = SPI_Direction_2Lines_FullDuplex;
  SPI_InitStructure.SPI_Mode = SPI_Mode_Master;
  SPI_InitStructure.SPI_DataSize = SPI_DataSize_8b;
  SPI_InitStructure.SPI_CPOL = SPI_CPOL_High;//SPI_CPOL_High   SPI_CPOL_Low
  SPI_InitStructure.SPI_CPHA = SPI_CPHA_2Edge;//SPI_CPHA_1Edge  SPI_CPHA_2Edge
  SPI_InitStructure.SPI_NSS = SPI_NSS_Soft;
  SPI_InitStructure.SPI_BaudRatePrescaler = SPI_BaudRatePrescaler_4;
  SPI_InitStructure.SPI_FirstBit = SPI_FirstBit_MSB;
  SPI_InitStructure.SPI_CRCPolynomial = 7;
  SPI_Init(SPI3, &SPI_InitStructure);


  /*!< Enable the sFLASH_SPI  */
  SPI_Cmd(SPI3, ENABLE);
}


void FLASH_LowLevel_Init(void)
{
  GPIO_InitTypeDef GPIO_InitStructure;

        GPIO_PinRemapConfig(GPIO_Remap_SPI3, ENABLE);

  /*!< sFLASH_SPI_CS_GPIO, sFLASH_SPI_MOSI_GPIO, sFLASH_SPI_MISO_GPIO
       and sFLASH_SPI_SCK_GPIO Periph clock enable */
  RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA | RCC_APB2Periph_GPIOC | RCC_APB2Periph_AFIO, ENABLE);


  /*!< sFLASH_SPI Periph clock enable */
  RCC_APB1PeriphClockCmd(RCC_APB1Periph_SPI3, ENABLE);

  /*!< Configure sFLASH_SPI pins: SCK */
  GPIO_InitStructure.GPIO_Pin = 10;
  GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
  GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
  GPIO_Init(GPIOC, &GPIO_InitStructure);


  /*!< Configure sFLASH_SPI pins: MOSI */
  GPIO_InitStructure.GPIO_Pin = 12;
  GPIO_Init(GPIOC, &GPIO_InitStructure);


  /*!< Configure sFLASH_SPI pins: MISO */
  GPIO_InitStructure.GPIO_Pin = 11;
  GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING;
  GPIO_Init(GPIOC, &GPIO_InitStructure);

  /*!< Configure sFLASH_CS_PIN pin: sFLASH Card CS pin */
  GPIO_InitStructure.GPIO_Pin = 4;
  GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;
  GPIO_Init(GPIOA, &GPIO_InitStructure);
}
