Compiler error for ESP32-CAM configuration

crashbash · January 23, 2022, 11:07pm

Hello guys,

I am facing next problem while trying to compile for ESP32-CAM.
I am using this quiet simple post The Eye of the Home. Building a home camera for less than… | by Ivan Lesar | Medium which provides next config:

esphome:
  name: esp_cam
  platform: ESP32
  board: esp32cam

wifi:
  ssid: "**********"
  password: "**********"


captive_portal:

# Enable logging
logger:

# Enable Home Assistant API
api:

ota:

esp32_camera:
  name: My Camera
  external_clock:
    pin: GPIO0
    frequency: 20MHz
  i2c_pins:
    sda: GPIO26
    scl: GPIO27
  data_pins: [GPIO5, GPIO18, GPIO19, GPIO21, GPIO36, GPIO39, GPIO34, GPIO35]
  vsync_pin: GPIO25
  href_pin: GPIO23
  pixel_clock_pin: GPIO22
  power_down_pin: GPIO32
  resolution: 640x480
  jpeg_quality: 10

Compiler throws next errror:

I have last versions of HA(2021.12.10) and EPSHome(2022.1.1).
Best regards,
Oleg

nickrout · January 24, 2022, 8:05am

Latest is not a version.

crashbash · January 24, 2022, 9:05am

Thx, added versions in main post.

crashbash · January 25, 2022, 4:48pm

So… anybody?

nickrout · January 25, 2022, 7:30pm

Does the compilation finish?

crashbash · January 26, 2022, 6:24pm

Looks like linkage problem, not compilation… you can see above log. I think in few days I will try to compile some other configs in ESPHome add-on to see if that problem is related to esp32-cam or is it more general one. Or just will wait till fixed version

nickrout · January 26, 2022, 7:10pm

Yes sorry, I meant does the firmware creation complete?

crashbash · January 26, 2022, 8:15pm

No, it fails.

nickrout · January 26, 2022, 8:17pm

Maybe the platformio forum can help.

crashbash · February 2, 2022, 1:44pm

Created new config based on that from article and default which is generated by ESPHome when you are creating new device:

esphome:
  name: camera

esp32:
  board: esp32cam
  framework:
    type: arduino

  # Enable fallback hotspot (captive portal) in case wifi connection fails
  ap:
    ssid: "Camera Fallback Hotspot"
    password: "***************"

captive_portal:
  


esp32_camera:
  name: camera
  external_clock:

  href_pin: GPIO23
  pixel_clock_pin: GPIO22
  power_down_pin: GPIO32
  resolution: 640x480

I have not yet tried to test the camera, but at least compilation is ok:
