<err> net_if: There is no network interface to work with! [ESP32-S3-Devkit] Zephyr 3.6.0

[rvalvekar]

I have been trying to run the sample/net/wifi example on ESP32-S3 Devkit Board. The Build for the program is successfully being built. The Flashing process is also executed without any issues. When i run the west espressif monitor i see the following output :

The Error - There is no network interface to work with is where I am stuck. Other issues mention of a example wifi_station, but i did not find this example in the zephyr repo.

Any help or direction how this could be resolved, would be highly appreciated.

Thank you ! Rohan.

You've installed Espressif's binary blobs, yes?

Espressif HAL requires WiFi and Bluetooth binary blobs in order work. Run the command below to retrieve those files. west blobs fetch hal_espressif

Yes, i have installed binary blobs, and then executed west update. But still this error is seen.

Thanks !

@rvalvekar, which esp32s3 module? Please, take a look at samples/net/wifi/boards and make sure you have the necessary overlay/conf files, which enables the wifi interface.

@sylvioalves - I am using ESP32-S3-WROOM-1 N16R8. I was able to build couple of other codes, without any issues. I do have conf and overlay files added.

[sylvioalves]

Is it devkitc or devkitm?

[rvalvekar]

@sylvioalves - It is ESP32 devkitc,

[sylvioalves]

This PR #72286 fix it. Anyway, you are missing the .conf and .overlay for esp32s3_devkitc in boards folders. Have you created it properly?

[rvalvekar]

@sylvioalves - Yes ihave created it properly. I will check the fix, and will update. Thanks for your support.

[sylvioalves]

@sylvioalves - Yes ihave created it properly. I will check the fix, and will update. Thanks for your support.

OK, let me also check here.

[rvalvekar]

@sylvioalves - Once the fix is implemented, would i just execute "west update" to get all the new changes that you have mentioned in PR #72286 ?

[sylvioalves]

@sylvioalves - Once the fix is implemented, would i just execute "west update" to get all the new changes that you have mentioned in PR #72286 ?

Pull latest master and then west update.

I've tested the devkitc and it worked. Added 'esp32s3_devkitc_procpu.overlay' and 'esp32s3_devkitc_procpu.conf' into boards folder.

[rvalvekar]

@sylvioalves - Alright. I will check and update on this thread. Again thanks for the quick support.

[rvalvekar]

@sylvioalves - Any solution for overflow in the iram_seg ? I checked a similar issue, and tried the solution of changing the size, but it has not helped.

It now takes the board overlay and configurations without giving me an error while building, but this is new.

below is the error output while building -

[sylvioalves]

@rvalvekar, reason is that this model is missing proper board configuration in mcuboot port. This fix it: https://github.com/mcu-tools/mcuboot/pull/1953

You can manually create this file to overcome current build error.

This is a new topic regarding same WIFI and drivers - undefined reference to `wifi_mgmt_connect'

With the help of your new overlays, it was possible to build the binaries, but still it is not detecting interface. So I am trying something else, and i encountered this error.
