spi flash driver is tested and working fine.
///////////////////////////usbd_stoarge_if.c////////////////////////////////

chipsector_erase_call(add_blk);
SST25Write(add_blk,(uint8_t *)buf,blk_len);
return (USBD_OK);
/* USER CODE END 7 */
}
above is the code ,kindly let me know what could be the problem.
The spi flash has a minimum 4096 erase so i have tried this
out add_blk =blk_addr*0x1000.
I have tried :
#define STORAGE_LUN_NBR 1
#define STORAGE_BLK_NBR 0x100
#define STORAGE_BLK_SIZ 0x200
again while formatting it fails
when i try
I have tried :
#define STORAGE_LUN_NBR 1
#define STORAGE_BLK_NBR 0x100
#define STORAGE_BLK_SIZ 0x1000
formatting does not even start the code gets hanged.
let me know any suggestions ,thanks in advance.
