@brief Convenience function to initialize read-only FAT filesystem and register it in VFS
This is an all-in-one function which does the following:
- finds the partition with defined partition_label. Partition label should be configured in the partition table.
- mounts FAT partition using FATFS library
- registers FATFS library with VFS, with prefix given by base_prefix variable
@note Wear levelling is not used when FAT is mounted in read-only mode using this function.
@param base_path path where FATFS partition should be mounted (e.g. “/spiflash”) @param partition_label label of the partition which should be used @param mount_config pointer to structure with extra parameters for mounting FATFS @return - ESP_OK on success - ESP_ERR_NOT_FOUND if the partition table does not contain FATFS partition with given label - ESP_ERR_INVALID_STATE if esp_vfs_fat_spiflash_mount_ro was already called for the same partition - ESP_ERR_NO_MEM if memory can not be allocated - ESP_FAIL if partition can not be mounted - other error codes from SPI flash driver, or FATFS drivers
