Issue compiling esphome 2024.6.1 on esp32-c6

[ss89]

The problem

I know the esp32-c6 is not officially supported (why actually? It's old enough and sdk is feature complete enough as well).

Still i would like to be able to compile esphome for this device.

It has worked for me for a long time, but stopped working with 2024.6.1 (didn't try 2024.6.0, as HA didn't show it to me).

Does anyone have a hint on how to make it comile again? I tried multiple esp-idf versions (5.2.0, 5.2.1, 5.2.2) and platform_versions (6.7.0, 6.6.0, 6.5.0, 6.4.0)

Which version of ESPHome has the issue?

2024.6.1

What type of installation are you using?

Home Assistant Add-on

Which version of Home Assistant has the issue?

2024.6.3

What platform are you using?

ESP32

Board

esp32-c6-devkitc-1

Component causing the issue

wifi

I'm in the same boat. The problem is with this PR: https://github.com/esphome/esphome/pull/6756. The esp_eap_client.h header file is only available in IDF >= 5.2 and not 5.1.

[goldmann]

After I upgraded to IDF version 5.2.2 I was able to compile ESPHome (in my case) 2024.6.1.

After I upgraded to IDF version 5.2.2 I was able to compile ESPHome (in my case) 2024.6.1.

Can you show your complete configuration? For me upping it to 5.2.2 gets me this error:

EDIT: I am compiling it using the esphome addon inside HA.

[goldmann]

Have you cleaned up build files before attempting to build it?

Here's the relevant part of my config. I had to clean it up by removing some sections.

substitutions:
  devicename: io-4

captive_portal: {}
web_server:
  port: 80
esp32:
  board: dfrobot_firebeetle2_esp32e
  variant: esp32
  framework:
    type: esp-idf
    version: 5.2.2
    platform_version: 6.7.0
esphome:
  name: $devicename

That board looks more like it is a regular esp32, not an esp32-c6 (different processor type).

Are you also using the firebeetle2 esp32e board or are you just compiling the firmware as if it was this board and then flash it to the esp32-c6?

[goldmann]

Ok, I must admit I totally missed the esp32-c6 board part of the report, I apologize for this. So, no, I do use the esp32e processor on the FireBeetle 2 (https://www.dfrobot.com/product-2195.html) board.

Seems that header file added in v5.1.2: https://github.com/espressif/esp-idf/tree/v5.1.2/components/wpa_supplicant/esp_supplicant/include
