Hi,

I added FATFS file system into my project (ethernet_to_serial). i am using FRDMK64F120,KDS 2.0 and KSDK1.1.0 examples project,

i tried following method. but when i open file its hanging somewhere i dnt know where its hanging.

give some solution.

CLOCK_SYS_EnableSdhcClock(0);

GPIO_DRV_Init(sdhcCdPin, NULL); //for card detection

config.transMode = kSdhcTransModeAdma2;

config.cdType = kSdhcCardDetectGpio;

if (SDHC_DRV_Init(BOARD_SDHC_INSTANCE, &host, &config) != kStatus_SDHC_NoError)

{

printf("FAILED SD CARD\r\n");

}

sdcard_disk_initialize(1);

SDCARD_DRV_Init(&host, &config);

ret=f_open(1,"read.txt",FA_READ);

if(ret==FR_OK)

{

printf("open SUCCESS\r\n");

printf("succ=%d",ret);

}

else //if(FR_DISK_ERR)

{

printf("open failed\r\n");

printf("error=%d",ret);

}

ret=f_read(ret,&f_data,4,1); //read

if(ret==FR_OK)

{

printf("WRITE SUCCESS\r\n");

}

else

printf("WRITE failed\r\n");

thanks and regards,
