    yes I did.

    In the meantime I found out what causes my issue:

    1. I forgot a decoupling cap at the ESP32 3.3V pin.
    2. The JTAG mini 10 pole cable/connector is a little bit unstable it seems.

    Now, sometimes the upload works, sometimes it does not. Not sure if OpenGDB combined with a non natively supported J-Link also add to this unstable behavior.

    J-Link works with dev boards like ESP32-WROVER.

    The issue is, I have a custom board and only have the JTAG interface. Maybe you can have a look at the ESP32 schematic if you see any issue?

    I was following this tutorial: https://visualgdb.com/tutorials/esp32/wroom/

    There it was suggested to use Embedded wizard.

    Anyways, for ESP-IDF wizard, I cannot connect to ESP32 over J-Link. I checked the pinning, it is correct.

    Here is the error log:
