Hi, I can't connect to STM32F030R8T6 using ST-LINK V2 and STM32CubeIDE on Ubuntu 18.04.5 LTS.

[Adam_K]

I use STM32F030R8T6 and an interface card that plugs into a breadboard for direct prototyping, ST-Link v2 STM32 and STM8 Programmer, both from Newbiehack.com.

Connected as on photo: SWDIO to pin 46 (PA13), SWCLK to pin 49 (PA14), GND to pin 62, 3.3V to pin 64. When I trying to launch I have got'Failed to start GDB server.

I changed setup in Debug Configuration from 'Autostart local GDB server'to 'Connect to remote GDB server'. After launch I got message 'Error in final launch sequence, Failed to execute MI command, connection timeout (przekroczony czas oczekiwania na połączenie).

When I used Nucleo-F767ZI with on-board ST-LINK debugger/programmer and STM32CubeIDE there was no any problem.

Is the hardware fault or software problem?

did you connect all VDD VDDA and GND pins? Did you pull BOOT0 low? See AN4325 Getting started with STM32F030xx and STM32F070xx series hardware development.

I checked again all connection, VDD connected to pins 1, 32, 64, GND connected to pins 31and 63, VDDA is not connected because I don't using it now, BOOT0 connected by 510 ohm resistor to GND

[KnarfB]

You need to connect VDDA too, see remarks in data sheet.

I connected VDDA Pin 13 to to 3.3V and VSSA Pin 12 to GND, unfortunately same problem remained.

Hi, finally I tick the option 'Shared ST-LINK' in Debug Configuration and launch is successful, LED flashing as expected, only red message' Info : default port : 7184

Info : Remote address: 127.0.0.1

Error: bind failed. Error = 98, exit' , I not understand it,

thank you so much for help, Adam

Hi,

finally solved the problem with red messages like

'Info : default port : 7184

Info : Remote address: 127.0.0.1

Error: bind failed. Error = 98, exit'

ST-Link-Server must be installed https://my.st.com/content/my_st_com/en/products/development-tools/software-development-tools/stm32-software-development-tools/stm32-performance-and-debuggers/st-link-server.license=1597223818543.product=ST-LINK-SERVER.version=1.3.0.html

Now everything working fine, thanks.
