Looks to be throwing a not ready error, have you set up the pin for the Card Detect (CD) input that is tested by SD_Detect().

Presumably you have the source, and could track this down?

Hi

Silly question.... Is the SD card formatted (FAT16 or FAT32)?

SD_Detect();  return 1 error

uint8_t SD_Detect(void) {   __IO uint8_t status = SD_PRESENT;   /*!< Check GPIO to detect SD */   if (GPIO_ReadInputDataBit(SD_DETECT_GPIO_PORT, SD_DETECT_PIN) != Bit_RESET)   {     status = SD_NOT_PRESENT;   }   return 0;    // i modified this to return 0 } now SD_Detect();  return 0 good SD_Init(); return 0 good disk_initialize(0);  return 0 good  disk_status(0) ; return 2 error disk_read(0,inbuf,0,1);  return 3 error

Then you'll need to do some debugging of your code, and hardware attachment. I have nothing to work with here.

Validate that your SDIO code is functioning outside of FatFs properly.

thank you clive1 no fatfs work with me my mistake i make  SD_Detect returnt with zero

but i make it return with 1 no it work thank you. uint8_t SD_Detect(void) {   __IO uint8_t status = SD_PRESENT;   return 1; }
