ESP32 Troubleshoot

Hello all I'm quite new to iOT things. Currently I'm having an issue with my esp32 project which is to detect the speed of vehicle using IR sensor. I would be happy is someone can show me step by step.

After try to debug the code on Arduino IDE, it says: OpenOCD: GDB Server Quit Unexpectedly. See gdb-server output for more details.

This is the full output for GDB server:

Waiting for gdb server to start...[2023-10-27T03:23:14.940Z] SERVER CONSOLE DEBUG: onBackendConnect: gdb-server session connected. You can switch to "DEBUG CONSOLE" to see GDB interactions.

hi @touaii

Are you familiar with what debugging a microcontroller entails?
Do you know GDB and OpenOCD?

From your post I think you erroneously believe that the debug will help you find bugs in your program, but it is instead a process of knowing the hardware you have attached to your machine, how to step through code etc.

Your issue might actually be of different sort.
If you confirm that you understand how to debug a microcontroller firmware then maybe I know which questions to ask.

Moreover, this forum section is for Arduino Nano ESP32.
Is this the board in your possession?

Looking forward to more input

regards

Hello I have the same problem and the same message with the arduino esp32 nano I followed the procedure on the arduino website and when I want to test the example "BLINK" I have the same m
essage that appears what can I do to make the debug function work with my arduino nano esp32?

You can start by reading the debugging guide... :wink:
Let us know if this helps!
