Debug support for Arduino Nano Esp32

[phant0mias]

Would it be possible to add debug suport for the Arduino Nano ESP32 (board = arduino_nano_esp32)

In the arduino espressif library it is included since release v2.0.12.
espressif/arduino-esp32#8567

As you switched to v2.0.14 in Dec 27, 2023 it might be possible

Thank you

Have you tried? Since it is a esp32-s3 it should work in general.

[phant0mias]

Yes I tried it. I have two differnet S3 (m5stack-cores3, esp32-s3-devkitc-1) and they work.
I configured it as

platform = espressif32
board = arduino_nano_esp32
upload_protocol = esp-builtin
debug_tool = esp-builtin

But nothing happens. The output in the degub terminal is:
DEBUG: Current (esp-builtin) External (cmsis-dap, dfu, esp-bridge, esp-builtin, esp-prog, iot-bus-jtag, jlink, minimodule, olimex-arm-usb-ocd, olimex-arm-usb-ocd-h, olimex-arm-usb-tiny-h, olimex-jtag-tiny, tumpa)
AVAILABLE: cmsis-dap, dfu, esp-bridge, esp-builtin, esp-prog, espota, esptool, iot-bus-jtag, jlink, minimodule, olimex-arm-usb-ocd, olimex-arm-usb-ocd-h, olimex-arm-usb-tiny-h, olimex-jtag-tiny, tumpa
CURRENT: upload_protocol = esp-builtin

I also tried to get it into boot mode using
https://docs.arduino.cc/tutorials/nano-esp32/debugging/
but no effort

Do you have any idea?

@phant0mias what happens if you run pio debug --interface-gdb -- -x .pioinit directly in the IDE terminal window.

could not find or open device!

The error message is quite descriptive, you sure all necessary drivers are installed for this board?

[phant0mias]

Hi,
thanks for your answer.

I have arduino 2.x IDE installed. Following the instructions in
https://docs.arduino.cc/tutorials/nano-esp32/debugging/
I got the same error.
Info : only one transport option; autoselect 'jtag'
Info : esp_usb_jtag: VID set to 0x303a and PID to 0x1001
Info : esp_usb_jtag: capabilities descriptor set to 0x2000
Warn : Transport "jtag" was already selected
Info : Listening on port 50005 for tcl connections
Info : Listening on port 50006 for telnet connections
Error: esp_usb_jtag: could not find or open device!

First I try to get it working in the arduino IDE (as it is an arduino product) and then I switch to platformio.....

[phant0mias]

I am in contact with arduino and will write when my problem is found

Closing as the issue is not related to PlatformIO.
