Settings sample shows -ENOENT on esp32s3 devkit

[dmalcorps]

Describe the bug

I am using an official esp32-s3-devkitc and I am trying to get the settings sample up and running, but while compiling works fine running does not. The serial output looks as follows:

*** THE END  ***

Building this for native_sim or a nucleo board works as expected.

To Reproduce

Simply build the settings example and run it:

west build -p always zephyr/samples/subsys/settings/ -b esp32s3_devkitc/esp32s3/procpu && west flash && west espressif monitor

Expected behavior

No "No such file or directory" error. Below is the output from a native_sim build:

*** Booting Zephyr OS build v4.0.0-293-gf537cf311d7a ***

*** Settings usage example ***

*** THE END  ***

Impact

This is a showstopper currently. Our plan is to use the settings subsystem in combination with the littlefs filesystem to store our application wide settings.

Environment (please complete the following information):

OS: Linux (Ubuntu 22.04)
zephyr: Latest git commit, but also tested with 3.7

[github-actions[bot]]

Hi @dmalcorps! We appreciate you submitting your first issue for our open-source project. 🌟

Even though I'm a bot, I can assure you that the whole community is genuinely grateful for your time and effort. 🤖💙

[Laczen]

Hi @dmalcorps, your board does not seem to have a conf file for the sample. Did you create one yourself? If not use the native_sim.conf (in the sample folder, under boards) as an example this is also using littlefs which is close to your final goal.

[sylvioalves]

@dmalcorps can you provide the full terminal log error? Sounds an environment issue. I have just tested the same board and it works properly.
