ESP-Thread-Border-Router with ESP32H2 and Adafruit Feather ESP32-S3

[dedro001]

Hello, I have problems with the ESP Thread Border Router Example (https://openthread.io/codelabs/esp-open ... hardware#1). Instead of the ESP Border Router Board I am using an ESP32H2 and an Adafruit Feather ESP32-S3. Unfortunately, flashing the border router code does not work (see attachment). The ESP32-S3 is connected to the ESP32H2 accordingly:
- TX: GPIO17
- RX: GPIO18
- Reset: GPIO 15
- Boot: GPIO 16

The ESP32H2 is also connected to GND and 3.3V.

The following has been set in the menuconfig:
- Thread Border Router Example:
- Border router board type: border router dev kit
- Board Configuration (see below)
- Example Connection Configuration: set my wifi ssid and password
- Component Config: enabled Comissioner

Thanks for your help.
