Hi all,

I'm trying to debug my code using Eclipse, I followed the espressif tuto : https://docs.espressif.com/projects/esp ... er-eclipse . I did exactly the same but when I'm launching the debugger I have the following problem :

Code: Select all

Error in final launch sequence:

Failed to execute MI command:
-target-select remote localhost:3333

Error message from debugger back end:
localhost:3333: Connexion terminée par expiration du délai d'attente.
Failed to execute MI command:
-target-select remote localhost:3333

Error message from debugger back end:
localhost:3333: Connexion terminée par expiration du délai d'attente.
localhost:3333: Connexion terminée par expiration du délai d'attente.

Does anyone know why I have this message ?

I'm using Eclipse IDE for C/C++ Developers Version: 2018-12 (4.10.0) with an Olimex-arm-ocd-usb-h and a JTAG cable.

Thank for your time

At the time when Eclipse reports this error, what output do you get from OpenOCD?

Start the GDB first using command:

Code: Select all

openocd -s share/openocd/scripts -f interface/ftdi/esp32_devkitj_v1.cfg -f board/esp32-wrover.cfg

Then start the debugging session on eclipse

ESP_igrr has asked like what output you are getting into OpenOCD console output while facing this issue. So that we can have idea like what can be issue into your case.

hi i am new to this,i want to debug my application in elipse.you have given command to start the gdb
where this command needs to to be entered..?
i am trying but it on command line but it says openocd command cannot be found

please help..!

The command should be entered on command line.
The paths to gdb and openocd should be set on system environment variables.

As a alternative solution to eclipse, you can try Visual Studio Code.

Here is a quick start guide for debugging esp32 on VsCode:
