I have got it working now, i switched to a Raspberry Pi to flash the program and setup the certificates.

This however is a workarround. My problem persists on a Windows pc.

Thanks for your answer, It's been a while for me, but i got time to work on it again. I did use the ESP-IDF command line. So that's not the issue. I can't see anything wrong with the serial connections as well, because the steps before the crash, like checking the chip, work. I also had te chance to...

I am trying to use the ATECC608B with the ESP32S3 using ESP-IDF 5.1 I have found the Crytpoauth utility https://github.com/espressif/esp-cryptoauthlib/tree/master/esp_cryptoauth_utility#readme Which seams to flash a program on the ESP32S3 that can configure the ATECC608B.

I can't see any updated code, is this still planned?
