LILYGO TTGO ESP32: Camera not working

[herangstl]

PROBLEM DESCRIPTION

After I configure the webcam and reboot the module the webcam is not working. With sample code the webcam is working fine, but not with Tasmota. Error message in the logs:

22:06:26.052 CAM: Init failed with error 0x20004

The ESP32 module I use is this one: https://github.com/LilyGO/ESP32-Camera https://www.banggood.com/LILYGO-TTGO-T-Journal-ESP32-Camera-Development-Board-OV2640-SMA-WiFi-3dbi-Antenna-0_91-OLED-Camera-Board-Geekcreit-for-Arduino-products-that-work-with-official-Arduino-boards-p-1379925.html

TO REPRODUCE

Apply template and reboot

EXPECTED BEHAVIOUR

webcam is working

SCREENSHOTS

[sfromis]

Looks like you did not apply the customized template for the device.

[herangstl]

Looks like you did not apply the customized template for the device.

The template you linked is not for my module. Unfortunately there are lots of different LILYGO TTGO modules out there.

I created my own template, double checked it - but still not working.

Do you know what this "Init failed with error 0x20004" actually means?

[sfromis]

Don't know, but a quick google search got an article where someone explains: The 0x2004 error means the camera is not supported Obviously 2004 instead of 20004 was just a typo.

I suspect that bad pin config could cause this, but this is of course just speculation.

Your configuration does not match the device. I have created a template for this device. {"NAME":"TTGO T-Journal ESP32 Camera","GPIO":[4928,1,1,1,1,5091,1,1,1,1,1,4960,1,5088,5093,5095,0,5184,5120,5056,0,5024,5152,4992,0,0,0,0,1,1,5090,5089,5094,0,0,5092],"FLAG":0,"BASE":1}

[mohnen]

The camera works, but not the display.

[mohnen]

Updated version with camera and display. Of course, you need to build your firmware for this manually. {"NAME":"TTGO T-Journal ESP32 Camera","GPIO":[4928,1,1,1,1,5091,1,1,1,608,640,4960,1,5088,5093,5095,0,5184,5120,5056,0,5024,5152,4992,0,0,0,0,1,1,5090,5089,5094,0,0,5092],"FLAG":0,"BASE":1}
