Failed to mount sdcard invalid argument5/24/2023 Call esp_vfs_fat_register() to specify:.Most applications use the following workflow when working with esp_vfs_fat_ functions: The function esp_vfs_fat_unregister_path() deletes the registration with VFS, and frees the FATFS structure. Subsequent operations on files starting with this prefix are forwarded to FatFs APIs. The function esp_vfs_fat_register() allocates a FATFS structure and registers a given path prefix in VFS. The header file fatfs/vfs/esp_vfs_fat.h defines the functions for connecting FatFs and VFS. This allows mapping of FatFs drives to physical disks at runtime. Although the library can be used directly, many of its features can be accessed via VFS using the C standard library and POSIX API functions.Īdditionally, FatFs has been modified to support the runtime pluggable disk I/O layer. ESP-IDF uses the FatFs library to work with FAT filesystems.
