@danielstosch:

Hi,
it seems something is wrong with your flashing, firmware is not loading at all.

• Which board are you using?
• Which flash method have you used?
  --> Web Installer is prefered and the easiest way to flash the devices

Manual flashing:

• Erase flash before reflash again
• Make sure you use the correct firmware package suitable for your device
• Flash with correct flash offsets, e.g. https://github.com/Slider0007/AI-on-the-edge-device/blob/develop/docs/Installation/DeviceReadme/freenove-esp32s3-n16r8.md

I used the web installer and also other methods.

My board is described as
ESP32 S3 N16R8 CAM Development Board 2,4G Wifi BT Kamera Modul für OV2640 OV5640 8 MB PSRAM 16 MB FLASH ESP32-S3WROOM N16R8

@danielstosch:

Thanks for reporting. There was an issue in the github web installer update script resulting in provisioning wrong bootloader file to web installer service. Only web installer was affected, though. It is fixed now (#271).

Just retry with web installer. Please report if it's working for you.

It is working now with the web installer. Great. Thanks.
But I did a manual flash before without success - but this is maybe caused by another problem.

Thanks again :)
