Hi all,
I my application I am interfacing SD card with nrf52 using FATFS file system. I am observing some weird behavior while doing this. I have two SD cards, one of 2GB sandisk and another of 8 GB Transcend. While using 2GB card all operations are happening properly like formatting card and writing to SD card. But when I am using 8 GB card and trying to format it I am unable to perform the operation. Following is my formatting function
void sd_format()
{
BYTE work[_MAX_SS]; /* Work area (larger is better for processing time) */
/* Create FAT volume */
ff_result = f_mkfs("", FM_FAT32, 0, work, sizeof work);
if (ff_result != FR_OK)
{
printf("Unable to format Disk\r\n");
return;
}
if (ff_result == FR_OK)
{
printf("Format Complete...\r\n");
return;
}
}
I am getting FR_DISK_ERROR while executing f_mkfs function. What could be the possible reason for this.
