STM32F030 cant be flashed with openOCD

[andreaslehmi9]

I'm tring to work with a STM32F030F4. Unfortunately I didn't manage to flash the application on the controller.

• I'm using openOCD with a ST-Link.
• I use the following to start openOCD: openocd.exe -f interface\stlink-v2.cfg -f target\stm32f0x.cfg
• I now use Telnet to talk to openOCD.

I do the following sequence:

 

 

Open On-Chip Debugger

0x08000060: ffffffff ffffffff ffffffff ffffffff ffffffff ffffffff

 

 

It seems that everything is fine as the communication with the chip works fine. Never the less I can't flash my application on the chip.

What could be the reason for that?
Could there be something missing on the hardware?

I'm using a selfmade board with:

• VDD and VDDA connected directly.
• Rst connected to a RC with 10k and 100nF
• Boot is connected directly to GND
• No external cristal

This are the Optionregister: 0x1ffff800: 00ff55aa 00ff00ff 00ff00ff 00ff00ff ffffffff ffffffff ffffffff ffffffff

This is the factory setting!

Thanks,

Which OpenOCD? ST has their own build of OpenOCD, shipped with CubeIDE (part of its debugger). Have you tried that?

[andreaslehmi9]

Thank you for the quick response.

I used openOCD in the the version: OpenOCD-20201228-0.10.0. This is used to be an official version from the openOCD homepage.

Will it only work with the ST version of openOCD? What are the differences?

 

I have a STM32CubeIDE installed and also found openOCD in one of the subfolders. Unfortunately I didn't find a stlink-v2.cfg I used stlink.cfg. When I call this version of openOCD I get some stramge errors. Maybe there are some environment settings missing.

Could you please tell me how I must call openOCE from the STM32CubeIDE to access my STM32F030 with my ST-Link?

The difference is simple: you use the ST version on STM32 and it works (if not - you can ask for support here). You run other version and waste time (and no support).

Create any CubeIDE project for your MCU or board. Even take any example from the ST "Cube" firmware package. Then debug it: create a new debug configuration and select OpenOCD as debugger engine. CubeIDE will create all needed configuration files. You then can copy them or edit manually if needed.
