Hi David, For SPIFFS to be programmed into flash when flashing the chip, you need to add spiffs_create_partition_image() into your CMakelists.txt. |

Still same problem. I have attached the build output if it helps.

Hi @david. You can do a diagnosis as follows. When the chip starts up it prints out the partition table You can also add the following at the beginning of your code esp_vfs_spiffs_conf_t esp_vfs_spiffs_conf = {
.base_path = "/spiffs",
.partition_label = NULL,
.max_files = 5,
.format_if_mount_failed = true};
esp_vfs_spiffs_register(&esp_vfs_spiffs_conf);
size_t total = 0;
size_t used = 0;
esp_spiffs_info(NULL, &total, &used);
ESP_LOGI("SPIFFS", "total %d, used %d", total, used);
esp_vfs_spiffs_unregister(NULL);This will print out the total SPIFFS and the used. Let me know what you find. The error might be code related and the SPIFFS data is present |

Interestingly I think I had the same issue which didn't happen if I used the command line.
Try opening an idf terminal and use idf.py flash monitor it should show the output and flash to spiffs
Let me know if this resolves it.
Regards,
Mair

Hi Mair,
I do have the FLASH_IN_PROJECT line in the makelist ok. and have not changed these since the software was last running ok.
It is difficult to see what the compiler is doing because the build output is not appearing in the VS code output window, it remains blank and I just see "Build Successful" at end. I though there must be a "silent build" option somewhere I can turn off in vscode but cannot find it.

Thanks MAir, Having so much trouble with VSCODE. There were errors for cmake commands not being found and the output kept defaulting to hidden so I could not see what was being compiled. My app has 2 spiffs partitions. One used for a log and other for html While I am waiting to try again, should I de-register spiffs every time after use or can I register it and leave it running to be able to simply add to my file as required? |

the latter is fine, Just be aware the code I presented assumes 1 partition. You will need to change the labels for it to work esp_vfs_spiffs_conf_t esp_vfs_spiffs_conf = {
.base_path = "/spiffs",
.partition_label = "<label>"
.max_files = 5,
.format_if_mount_failed = true};
esp_vfs_spiffs_register(&esp_vfs_spiffs_conf);
size_t total = 0;
size_t used = 0;
esp_spiffs_info( "<label>", &total, &used);
ESP_LOGI("SPIFFS", "total %d, used %d", total, used);
esp_vfs_spiffs_unregister( "<label>"; |

I have cleaned and rebuilt several times. No idea what is happening here. Having to reinstall esp-idf again in VScode because it could not find the toools folder files now. |

Its not going to be an issue with vscode. It doesn't do anything to your compilation.
If you can build other projects then it's not your IDF installation. Its more than likely a fault in the project somewhere. I would need to have a closer look to debug it.

I have cleaned and rebuilt several times.
Other projects were ok and a new test project with just one partition worked.
No idea what is happening here. Having to reinstall esp-idf again in VScode because it could not find the toools folder files now.

I think I have a bit of progress. I now at least see it is trying to organise the spiffs partitions and complaining I have not used correct base address |

Now it compiles but get "Failed to initialize Spiffs (ESP_ERR_INVALID_ARG) //There must be an error or wrong folder pointed to I have the 2 folders to program into flash above the main folder labelled The partitions are set up as In cmakelists I do this The code that uses log then the FILE commands attempt to open and then create file if not found. and code that uses html |

I can see the flash is being written ok to the partitions at 0011.... (log storage) and 0021...(html_storage) So, must be issue in spiffs init, are my base path and label correct ? esp_vfs_spiffs_conf_t log_config = esp_err_t ret = esp_vfs_spiffs_register(&log_config); It is failing in the "else" catch below... with an INVALID ARG response if(ret != ESP_OK) |
