How to deal wirh : Could not verify ST device! ?

PZwar
Associate II

Dear all,

Could not verify ST device!

This error popped up suddenly and blocks any progress. I took an older computer and had the same error again.

Therefore, I suspected a hardware failure and ordered new adapters and processor boards, but I kept having the same error again.

I have upgraded the STM32CubeIDE, the st-link drivers (dpinst_amd64.exe) and st-stlink-server(st-stlink-server.1.1.1-3.msi).

The st_link v2 adapter have been upgraded with the latest firmware.

Using STM32 Link Utility, I was able to program, verify and run blink applications.

I am using BluePills (STM32F103C8) with chinese adapters on a 64 bit Windows 10 machine.

Please find below the output produced when starting debugging in STM2CubeIDE using the GDB server in SWD mode.

I also selected the OPENOCD debugger, but it also failed, though in a different way.(see below)

Does anyone have a suggestion how to proceed on this?

Cheers, Paul

Hi !

I am not very fluent in SWD, but the verbose output from Open OCD helps to identify the issue : the ID read by both tools differs from what is expected. Meaning that the error is the same in both cases.

Your device under test reads back 0x2ba01477 while the tools expect 0x1ba01477. I don't think it can be an electrical problem. Since you are using a bluepill, maybe the microcontroller is a counterfeit product. You should ST about this, perhaps with a picture of the uC.

Could not verify ST device!

Thank you so much, Kraal!

I inspected the looks of the chip and found it quite different from the ones I used before.

The text was not engraved but printed in a sloppy way. I think that your suggestion of a counterfeit is right.

I tried to make these counterfeits working under STM32CUBEIDE and OpenOCD.

Therefore, I adapted the st_scripts/target/stm32f1x.cfg file by replacing the 0x1ba01477 by 0x2ba01477.

I also added a line:

reset_config trst_only

This gives a error message:

Error: BUG: can't assert SRST

Neverthless, I could load and debug my code.

Hi Paul,

I'm glad you find a way to use your dev board even if the device ID is not correct.

I would add that for test or learning purpose it is OKish to use the bluepill with the strange part as it is, but for anything that goes into production you should always use real product.

Best regards,

Kraal

Hi PZwar,

I have the same problem.

However I am unable to locate the "st_scripts/target/stm32f1x.cfg" file or folder on windows 10.

Using STM32CUBEIDE and OpenOCD.

Thanks & regards

Dear SWadi.1,
Since the problem occurred  I have  upgraded tp version  1.2.0 of
stm32Cubeide.
There are two versions of the file:
C:\ST\STM32CubeIDE_1.2.0\STM32CubeIDE\plugins\com.st.stm32cube.ide.mcu.debug.openocd_1.3.0.202002181050\resources\openocd\st_scripts\target\stm32f1x.cfg
and
C:\ST\STM32CubeIDE_1.2.0\STM32CubeIDE\plugins\com.st.stm32cube.ide.mcu.debug_1.2.0.201912201802\resources\openocd\st_scripts\target\stm32f1x.cfg
I modified the *first* file.
Success!

Hey PZwar,

Thanks found it!! 🙂

I am using STM32CubeIDE_1.3.0, found /stm32f1x.cfg --> path below

"C:\ST\STM32CubeIDE_1.3.0\STM32CubeIDE\plugins\com.st.stm32cube.ide.mcu.debug.openocd_1.3.0.202002181050\resources\openocd\st_scripts\target"

Got the STM32CubeIDE to download and debug code after doing the chip id changes.

Thanks

Hmm the MSB bits of the ID Code register are just a version number so 2 means newer than 1.. ?

If you replace 0x1ba01477 with 0x2ba01477 in stm32f1x.cfg, then it will work for the clone but not for the genuine STM32…

Instead do the following: >>

  • In the stm32f1x.cfg - file, find the command line (around line 62) starting with : swj_newdap
  • At the end of this command line you will see : -expected-id $_CPUTAPID
  • Simply change it to: -expected-id 0

The zero tells OpenOCD to ignore id numbers, which means all clones or genuine MCUs will work.

  • Save the changes. Now your flash and debug should work.

hey JElli.1,

Thanks for the new info..

I tried it and it works for the clone. 😎 👍

But my order for the original is still not delivered thanks to COVID-19.. shall update once i test both.
