STM3210C_eval evaluation board to read 4G SD card

Target: STM32_EVAL evaluation board 

with STM32F107VC

Tools: ST-Link/V2

Does anyone know how to read 4G SD (or more) card ?!how can I fix it?!I used fatfs to operate SD card, when 2G SDcard plugged in the slot, it's fine.But 

plugged more than 2G SDcard, it doesn't work.

The block addressing scheme must not use a byte offset via a 32-bit variable, and the code would need to support SDHC cards which use a slightly different command expectation.

I'm not currently working on F1 platforms, or have this board.

Thanks for your reply.

I checked my fatfs the file object structure (FIL) show 

Force 32bits alignement

 so I think software it on the right way.Is it the H/W limitation on this D-board?Does any ideas to solve my problem? I will 

appreciate your help very much.

Thanks All.

No, it's really not a FatFs issue, it's the sector read/write routines for the SDIO/SPI layer below DISKIO.C

I've posted fixed routine for the F4 using SDIO.The F1 series has thisSTM32F10x_StdPeriph_Lib_V3.5.0\Utilities\STM32_EVAL\Common\stm32_eval_sdio_sd.cThe ReadAddr here is broken because it uses a 32-bit variable that isn't going to hold an offset >4GB properly./**  * @brief  Allows to read one block from a specified address in a card. The Data  *         transfer can be managed by DMA mode or Polling mode.  * @note   This 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.  * @param  readbuff: pointer to the buffer that will contain the received data  * @param  ReadAddr: Address from where data are to be read.  * @param  BlockSize: the SD card Data block size.

Thanks for your reply.

Well, I got the same

characterization 

in 

stm32f1XX series

 peripheral library

  * @brief  Reads block(s) from a specified address in an SD card, in polling mode.   * @param  p32Data: Pointer to the buffer that will contain the data to transmit  * @param  ReadAddr: Address from where data is to be read    * @param  BlockSize: SD card data block size, that should be 512  * @param  NumberOfBlocks: Number of SD blocks to read   * @retval SD statusuint8_t BSP_SD_ReadBlocks(uint32_t* p32Data, uint64_t ReadAddr, uint16_t BlockSize, uint32_t NumberOfBlocks){==============================================Do you have any suggestion to fix it that I can read/write 4G(above) SD card?!I will 

appreciate your help very much.
