I’ve beet trying for days and days now to make SPIFFS work on my esp32 board using PlatformIO in VSCode following the following example: https://github.com/espressif/esp-idf/tree/master/examples/storage/spiffs but I can’t just make it work. If I use the Arduino framework it will mount the partition without any problems but when I try to do it with ESP-IDF framework it just wont create the partition nor reformat flash memory if doesn’t find the partition I’m looking for.

the logs are as follows:

    \$\begingroup\$ To use SPIFFS, you must partition the flash memory such that space is allocated for SPIFFS? What partitioning are you using? Please show the platformio.ini file. Also see: docs.platformio.org/en/latest/platforms/… \$\endgroup\$ – Codo Nov 29 '19 at 14:07
  • \$\begingroup\$ @Codo I believe you're completely right, that was my main suspect. My question now would be, in VSCode, where in my project would I have to put my partition table? \$\endgroup\$ – Marco Castro Nov 29 '19 at 17:38

I've found an answer for this issue as stated in the following thread: https://community.platformio.org/t/vscode-esp-idf-framework-esp32-spiffs-error/10817.

The problem was basically I was trying to access a partition that never existed in my partition table. I downloaded the csv file from the example and placed it in the root directory (where platformio.ini is located) then I was able to access the "spiffs" partition to store data

Define partition table in platform.ini like this:

board_build.partitions = custom_16MB.csv

Inside file is something like :

Name, Type, SubType, Offset, Size, Flags

nvs, data, nvs, 0x9000, 0x5000,

otadata, data, ota, 0xe000, 0x2000,

app0, app, ota_0, , 0x640000,

app1, app, ota_1, , 0x640000,

spiffs, data, spiffs, , 0x370000,

This is my partition table for 16Mb ESP32.

How to define custom partition tables:
