Posted on January 21, 2016 at 08:53Hi everyone ,
I develop FatFs file system on SST26VF016B 2MB SPI Flash.I have done raw read/writes. I can success Fully read/write all SPI flash addresses.
My problem is i create file system and i create file but i'm not write any data on file.Because disk is full error.
I am using this define in ffconf.h
&sharpdefine _MIN_SS 512
&sharpdefine _MAX_SS 512
My diskio.c implementation like this,
DRESULT disk_ioctl (
BYTE pdrv, /* Physical drive nmuber (0..) */
BYTE cmd, /* Control code */
void *buff /* Buffer to send/receive control data */
)
{
DRESULT res;
uint8_t status;
status=SST_Status();
switch(cmd)
{
case CTRL_SYNC:
if(status & 0x01)
res=RES_ERROR;
else
res=RES_OK;
break;
case GET_SECTOR_COUNT:
*(DWORD*)buff=4096;
res = RES_OK;
break;
case GET_SECTOR_SIZE:
*(WORD*)buff=512;
res = RES_OK;
break;
case GET_BLOCK_SIZE:
*(DWORD*)buff=1;
res = RES_OK;
break;
};
return res;
}
and
i use f_mkfs('''',0,4096);
Whats the wrong?Why i get disk_full error?
Thanks for help
Best Regards
