Debugging STM32 with ST Link Remotely

In this video I will show how you can debug any STM32 device remotely ( can be any where in the world if you have VPN ) using a low cost Raspberry Pi.

From the video:
0:00 - Introduction

1. Net Analyzer

3. Putty:

4. To update the Raspberry:
sudo apt-get update
sudo apt-get upgrade

5. min:
2.53: install openocd
sudo apt-get install openocd

3:30 - openocd configuration

7. Min.
7:40 - CubeIDE configuration

8. Min.
9:40 - Check the network:
netstat -an | grep tcp

Bindto 0.0.0.0 means to accept connections from any IP. Good tutorial

Thanks so much for this cool tutorial, any update for 2024 year and Raspberry Pi 4 hardware?

Thank you! Awesome!
Unfortunately, ST has no support "st-link server" for linux using ARM processors.. heh, who need this solution works fine, with debugger and flasher! :)

Hey, I have a question. I want to use openOCD with different stm nucleo board, i used your cfg file but if i type "open ocd -f openocdf4.cfg" the openocd not worked. This is the last line from debug.
Debug: 448 217 target.c:1991 freeing all working areas
Debug: 449 217 hla_interface.c:117 hl_interface_quit(): hl_interface_quit
Debug: 450 218 stlink_usb.c:1319 stlink_usb_exit_mode(): MODE: 0x02
How about this?

Hi I am facing problems running sudo openocd it says error while shared libraries: libgpio.so.2. I tried to install libgpiod2 but still failed (even with apt —fix-broken install). My current OS is bullseye


Really appreciate any help

Hi,

I followed all the steps but when i do the debug connection the raspberry says:

Info : accepting 'gdb' connection on tcp/3333
Info : device id = 0x10016418
Info : flash size = 128kbytes
undefined debug reason 7 - target needs reset
invalid command name "ReadAPEx"
Info : dropped 'gdb' connection

And I can't connect :(

Help please

Hi, Thanks, openocd just returns immediately after executing it without any specific error (even in debug mode), I am using STM32H7

Hi. I was using this process to debug using OpenOCD successfully until Cube IDE version 1.6. but when i upgraded this to a newer version, it is giving me error of Could not verify ST device.

I know many people face this issue. But i am unable to solve it. Can you please help me if u know the answer?
