Cannot download code into STM32f103 by St-Link v2 in STM32CubeIDE

HI,

I have trouble with downloading code in MCU STM32F103 (Blue Pill) by ST-Link v2.

I have also try to download, read, erase MCU by STM32CubeProgrammer and it works correctly.

Project was made by STMCube as Atolic project and after that it was converted to STMCubeIDE project. Firmer, which is made by STMCubeIDE and downloaded in MCU by STMCubeProgrammer works as expected.

What if you first use CubeProgrammer to do a full chip erase, and then try to use CubeIDE with ST-LINK GDB-server to start a debug session (and thereby flash the application)?

Does that work?

I've tried it one more time. Unfortunately without success. Please take a look on snippets form CubeIDE and Cube Programmer.

Version of CubeProgrammer is v2.1.0, CubeIDE is 1.0.2

STM32CubeIDE works only with genuine STM32 parts.

Make sure that your BluePill board embeds a genuine STM32 device.

Hello,

ST Link v2 is original STM product bought from famous distributor in EU. You can see picture below.

BluePill is bought on open market but MCU is origin STM product. I hope, I can not believe that there are "fake" STM MCU's on market.

From my point off view, it looks like that GDB - server can not establish connection with ST LInk. Why, I do not know. Also, I can not understand how CubeProgrammer can deal with that MCU but CubeIDE can not.

In meanwhile, I have tried to utilize JTAG but without success. I could use CubeProgrammer, but could not CubeIDE.

>>Also, I can not understand how CubeProgrammer can deal with that MCU but CubeIDE can not.

Probably because the latter uses OpenOCD or some crappy DLL/Driver combination.

Check the settings/configuration items for the GDB Server, perhaps try less aggressive clocks settings if those are options. Enable Verbose mode so you might get richer diagnostic information.

Likely also works properly under Keil.

OK, thanks for support.

I will try to replace MCU or buy new BluePill.

Thanks.

Hi, I am having a similar problem. I put the boot0 at 1 and worked. It doesn't feel right. When I used ac6 openSTM, I don't remember of doing that. Is that correct?

With similar problem, do you mean that you get the "Reason (18) Could not verify ST device. Abort connection." error?

Ac6 with OpenOCD debugger back-end did not perform the clone device detection. CubeIDE with ST-LINK GDB server does. So, assuming your bluepill embeds a cloned ST device, this is perfectly expected.

If other error message, then please elaborate.

Hello Mattias, indeed. I wasn't clear enough.

Steps to reproduce:

1) Use a bluepill STM32F103C8 + St-link V2 + Stm32CubeIDE

2) Leave all configs as default and try to debug

I was running over and over my configurations. I was able to fix the problem.

As it seems, using native Stm32CubeMX ioc generate the problem. When it ask, do the migration for STM32CubeIDE.

Problem solved!

@TMaia.1, hmmm... interesting. MX itself is not "CubeIDE debug configuration"-aware.

The only reasons we can think of as to why "using native Stm32CubeMX ioc generate the problem" would be if MX uses the SWD/JTAG pins for some other function and thereby not making them available for debugger. You could double-check that if you want... Then again if your problem is solved - I am happy :)
