Hi All,
Anyone has tried the new library offering the FATFS with VFS interface, which mount into the spi flash?
I've tried with the convenient function " esp_vfs_fat_spiflash_mount", but always returned error.
I've tried to compile the example "wear_leveling", but the example itself not working too.
Anyone able to get it to work?
The same error message return when mounting the file system to spi flash, as below:
**********************************************************************************
W (1156) vfs_fat_spiflash: f_mount failed (13)
I (1156) vfs_fat_spiflash: Formatting FATFS partition
E (1156) vfs_fat_spiflash: f_mkfs failed (14)
E (1166) example: Failed to mount FATFS (0xffffffff)

Re: New LIbrary vfs_fat_spiflash not working
Hello,
I get the same problem.
https://github.com/Ebiroll/qemu_esp32/b ... creenlog.0
Really nice if it did work.
Do you have any example on how to use VFS with some other filsystem? SPIFF?

Re: New LIbrary vfs_fat_spiflash not working
Sorry about that issue. The PR and a bunch of other fixes related to FATFS and wear levelling are in the merge queue, should be in master soon.
Edit: fix has been released to Github in 33b8b78.

Re: New LIbrary vfs_fat_spiflash not working
I tried the new esp-idf, formatting the disk seems to work OK but it fails on fopen() vfs_fat_open: fresult=13
Only tested in qemu so I think the error is in qemu .
Here is the MBR from the qemu-flash,

Re: New LIbrary vfs_fat_spiflash not working
For the record. It was an error in QEMU, now it works fine.
You can also mount the FAT image,
mkdir fat_partition
sudo mount -o loop,offset=0x110000 esp32flash.bin fat_partition
ls fat_partition
????? hello.txt
However reading the file did not work.
od -h fat_partition/hello.txt
0000000 0000 0000 0000 0000 0000 0000 0000 0000
Maybe it works better with an actual dump of the flash.
To make a dump of flash try,
~/esp/esp-idf/components/esptool_py/esptool/esptool.py --baud 920600 read_flash 0 0x400000 esp32flash.bin

Re: New LIbrary vfs_fat_spiflash not working
Thanks all for the info!!!
After updated the esp-idf, it's working now!
But another thing to double check, I found that the file extension has some limitation right?
From what I tested, the file name extension can only be "name.ext".
1. file extension (the ".ext") can't go for more than 3 characters
2. you can't create a file as "name.ext.ext"
