问答对人有帮助，内容完整，我也想知道答案 0 芯片：ESP32-WROVER-B IDF版本：release/v4.3 开发环境：Windows10 各位好，我遇到spiffs初始化失败的问题，但我感觉我给的config应该没啥问题？ esp_vfs_spiffs_conf_t conf = { .base_path = "/abcdefghi_files", .partition_label = NULL, .max_files = 4, .format_if_mount_failed = false}; 整段代码如下： Code: Select all void storageInit() { static const char* tag = "storageInit"; ESP_LOGD(tag, "storageInit() called"); esp_vfs_spiffs_conf_t conf = { .base_path = "/abcdefghi_files", .partition_label = NULL, .max_files = 4, .format_if_mount_failed = false}; // Use settings defined above to initialize and mount SPIFFS filesystem. // Note: esp_vfs_spiffs_register is an all-in-one convenience function. esp_err_t ret = esp_vfs_spiffs_register(&conf); if (ret != ESP_OK) { if (ret == ESP_FAIL) { ESP_LOGE(tag, "Failed to mount or format filesystem"); throw std::runtime_error("fail to mount"); } else if (ret == ESP_ERR_NOT_FOUND) { ESP_LOGE(tag, "Failed to find SPIFFS partition"); throw std::runtime_error("no partition"); } else { ESP_LOGE(tag, "Failed to initialize SPIFFS (%s)", esp_err_to_name(ret)); throw std::runtime_error("fail to init"); } return; } size_t total = 0, used = 0; ret = esp_spiffs_info(NULL, &total, &used); if (ret != ESP_OK) { ESP_LOGE(tag, "Failed to get SPIFFS partition information (%s)", esp_err_to_name(ret)); } else { ESP_LOGD(tag, "Partition size: total: %d, used: %d", total, used); } } 然后串口打印如下 D (1823) storageInit: storageInit() called D (1833) partition: Loading the partition table D (1843) SPIFFS: SPIFFS_mount sz:0 logpgsz:0 logblksz:0 perasz:0 addr:00000000 fdsz:192 cachesz:1124 D (1923) SPIFFS: page index byte len: 256 D (1923) SPIFFS: object lookup pages: 1 D (1923) SPIFFS: page pages per block: 16 D (1923) SPIFFS: page header length: 5 D (1933) SPIFFS: object header index entries: 87 D (1933) SPIFFS: object index entries: 124 D (1943) SPIFFS: available file descriptors: 4 D (1943) SPIFFS: free blocks: 255 D (1953) SPIFFS: SPIFFS_unmount E (1953) storageInit: Failed to initialize SPIFFS (ESP_ERR_INVALID_ARG) 请问这个ESP_ERR_INVALID_ARG是怎么导致的？我的sdkconfig里spiffs相关的内容如下 # # SPIFFS Configuration # CONFIG_SPIFFS_MAX_PARTITIONS=3 # # SPIFFS Cache Configuration # CONFIG_SPIFFS_CACHE=y CONFIG_SPIFFS_CACHE_WR=y # CONFIG_SPIFFS_CACHE_STATS is not set # end of SPIFFS Cache Configuration CONFIG_SPIFFS_PAGE_CHECK=y CONFIG_SPIFFS_GC_MAX_RUNS=10 # CONFIG_SPIFFS_GC_STATS is not set CONFIG_SPIFFS_PAGE_SIZE=256 CONFIG_SPIFFS_OBJ_NAME_LEN=128 # CONFIG_SPIFFS_FOLLOW_SYMLINKS is not set CONFIG_SPIFFS_USE_MAGIC=y CONFIG_SPIFFS_USE_MAGIC_LENGTH=y CONFIG_SPIFFS_META_LENGTH=4 CONFIG_SPIFFS_USE_MTIME=y # # Debug Configuration # CONFIG_SPIFFS_DBG=y CONFIG_SPIFFS_API_DBG=y CONFIG_SPIFFS_GC_DBG=y # CONFIG_SPIFFS_CACHE_DBG is not set CONFIG_SPIFFS_CHECK_DBG=y CONFIG_SPIFFS_TEST_VISUALISATION=y # end of Debug Configuration # end of SPIFFS Configuration partition如下： # Name, Type, SubType, Offset, Size, Flags # Note: if you have increased the bootloader size, make sure to update the offsets to avoid overlap nvs, data, nvs, 0x9000, 0x6000, phy_init, data, phy, 0xf000, 0x1000, factory, app, factory, 0x10000, 1M, storage, data, spiffs, , 1M, storage里面只有一个文件，文件名长度24字节，文件大小46字节 0
