new vfs_fat_spiflash library

[andymakespasta]

Hello. Thanks for implementing the new wear leveling fatfs spiflash library.
It's exactly what I've been looking for.

Unfortunately,

When I compile and run the example code at (esp-idf/examples/storage/wear_levelling) on an ESP WROOM-32
It fails when trying to "Formatting FATFS partition"
, more specifically, it fails the MBR check at (esp-idf/components/fatfs/src/ff.c), function f_mkfs(), line 5267, 5268:

Code: Select all

if (disk_read(pdrv, buf, 0, 1) != RES_OK) return FR_DISK_ERR;	/* Load MBR */
if (ld_word(buf + BS_55AA) != 0xAA55) return FR_MKFS_ABORTED;	/* Check if MBR is valid */

The memory there is empty 0x0000.
Has anyone gotten the new library to run?

Thanks!

Hello,
I get the exact same problem.

https://github.com/Ebiroll/qemu_esp32/b ... creenlog.0

Obviously it will be fixed or the example may be removed. It could be possible that it works if you manually flash a FAT partition as f_mkfs seems to fail when checking for a valid Master Boot Record. (MBR)
Row 5268 in file ff.c

/*-----------------------------------------------------------------------*/
/* Create FAT file system on the logical drive */
/*-----------------------------------------------------------------------*/

FRESULT f_mkfs (
const TCHAR* path, /* Logical drive number */
BYTE opt, /* Format option */
DWORD au, /* Size of allocation unit [byte] */
void* work, /* Pointer to working buffer */
UINT len /* Size of working buffer */
)
....
/* Determine where the volume to be located (b_vol, sz_vol) */
if (_MULTI_PARTITION && part != 0) {
/* Get partition information from partition table in the MBR */
if (disk_read(pdrv, buf, 0, 1) != RES_OK) return FR_DISK_ERR; /* Load MBR */
