Hi @Halfnium, We have integrated OpenOCD debugging with the Espressif IDF Eclipse plugin. Please check this here https://github.com/espressif/idf-eclipse-plugin/#gdb-openocd-debugging Please update to the latest version of the plugin v1.2.2 to get the OpenOCD debugging updates. https://github.com/e...

Hi Halfnium, do you mean the problem is that the documentation at https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/jtag-debugging/using-debugger.html#jtag-debugging-using-debugger-eclipse doesn't contain instructions for launching OpenOCD from Eclipse? ESP_igrr, Yes, that is w...

I have succeeded in edit / compile / build / flash / run with ESP32 WROOM in the guise of SparkFun's ThingPlus board, with both command line and Eclipse. I have also succeeded in OpenOCD and GDB debug in two cooperating command-line windows. I'm using a Chinese-sourced FT2232HL board with quite thin...

Does this mean that JTAG debugging also is not possible unless / until the AT application has been removed via "esptool.py erase_flash?"

Secondly, how would one restore the AT application in future, should that be desired?

Angus, I may have to eat my hat. I set out to reproduce the problem as described earlier in this thread but have not been able to make it happen again: the declaration of main() as extern "C" is sufficient. Maybe this is something subtle that only happens as part of the newbie workflow. Or maybe I m...

Hugo, Not quite sure, but it seems I jogged you toward finding your solution. If so, I'm glad. On my Ubuntu system, 'java --version' yields openjdk 11.0.7 2020-04-14 OpenJDK Runtime Environment (build 11.0.7+10-post-Ubuntu-3ubuntu1) OpenJDK 64-Bit Server VM (build 11.0.7+10-post-Ubuntu-3ubuntu1, mix...

ESP_Angus, Yes, I had noticed those C++ guards when perusing the include files. Nonetheless, Eclipse (2020-06 version) refused to resolve the references until I put them inside the "extern C." Building from Eclipse otherwise failed with 23 unresolved references. I am also a new guy. I was so fixated...

zhenghaku, Many people (including me) have encountered this problem. Your and chegewara's solutions are correct. To help others understand, I have created a C++ version of the hello_world C-language example that Espressif provides within the IDF. Please find this attached. Note that the new source c...

hbouchard , At the risk of complicating the problem description, I am successful in using Eclipse 2020-06 (4.16.0), build id: 20200615-1200 with ESP IDF v4.2-dev-2243-gcf056a7d0 on Ubuntu Linux 20.04 LTS / Gnome 3.36.3. I have not tried using JTAG with or without Eclipse (since I don't have JTAG equ...

New to the ESP32, IDF I carefully watched the application build process. I was surprised to note that building the "hello_world" example in "../esp/esp_idf/examples/get-started" generates files named "hello-world" (of types .bin, .elf and .map). That's right, a dash crept into the file names in plac...
