    Hello,

    at the moment I’m using VisualGDB 5.5R4 build 3920. With this revision, the ESP32-C3 doesn’t seem to be supported. Do you plan to support this chip?

    Thank you,

    Mattia Berton

    Hi,

    VisualGDB 5.6 Beta 3 already supports it, as long as you our latest ESP32 toolchain, ESP-IDF 4.3 and the most recent OpenOCD package.

    Hello,

    I have tried to make Jtag work on my board, but I haven’t been able. I can attach to ESP32, ESP32-S2, ESP8266, but with ESP32-C3 I put target/ESP32C3.cfg but I get the classic error as if I didn’t attach the JTAG adapter to the board.

    I checked my project, and I’m sure pin are attached to the correct IOs of ESP32C3. Is there any particular procedure to make JTAG work in ESP32-C3? I’m not using, at this moment, the USB/JTAG, only the classic JTAG.

    Thank you,

    Mattia Berton

    Hi,

    We have just received the ESP32-C3 hardware and finished running tests on it. Indeed, using the external JTAG pins doesnt’ seem to work at all. However, the built-in USB-to-JTAG engine works just fine. We have published a tutorial showing how to use it here and also contacted Espressif for clarifications on the external JTAG support.

    Update: we just received clarifications from Espressif on this issue. Debugging ESP32-C3 with an external JTAG probe requires additional setups steps described in this thread. However, using the built-in JTAG engine should be much easier.
