    Is there a description or manual on how-to do secureboot with a ESP32 with visualGDB ?

    Hi,

    This is something managed by the ESP-IDF itself and VisualGDB doesn’t have any special GUI for it. Please consider checking ESP-IDF documentation for more details.

    That said, VisualGDB ESP32 projects directly use the ESP-IDF build tools, so once you manually configure secure boot per ESP32 documentation, the rest of the VisualGDB functionality will still work as expected.
