Programming problems with STM32F103C8 and ST-LINK V2

[spider87]

Good morning everyone,

We bought a STM32F103C8T6 Evaluation Board ADS1256 (https://www.amazon.it/Lodokdre-STM32F103C8T6-acquisition-Industrial-Control/dp/B0C582B33D), after writing the firmware I am trying to debug it with the ST-LINK V2 programmer (https://www.digikey.it/it/products/detail/adafruit-industries-llc/2548/6827110). When loading the STM32CUBE IDE firmware I get the error:

Error in final launch sequence:

Failed to start GDB server
Failed to start GDB server
Error in initializing ST-LINK device.
Reason: (18) Could not verify ST device! Abort connection.

Reading some forums they advise me to use OpenOCD as a debugger, but even with this setting I can't communicate.

STM32CubeProggrammer allows me to communicate with the board, but at this stage of work I need the debugger.
Can someone kindly give me some advice?
Thank you very much
Gian

That's a 3rd-party board - not an ST board - so you'll need to contact the supplier for support.

Probably a high risk that it's not a genuine STM32.

That's definitely not a genuine ST-Link - see:

See above - most likely a fake chip on your board.

For best results, get a Nucleo board - which gives a genuine STM32, includes a genuine ST-Link, and is fully supported by ST.

PS:

The Nucleo is actually cheaper than just that Clone ST-Link at Digikey!

PPS:

It even says so on the Digikey listing!

Thanks for the reply @Andrew Neil 
Yes I understand for the programmer, I also have original programmers that I will try as soon as I am in the office.
For our application, the core board is not ideal because we are looking for a board that integrates both the high precision ADC and the MCU.
Is there no way to make the microcontroller recognized, not even with an original programmer? Possible solutions? A last chance is to replace the microcontroller, do you think I will solve the problem?

No - It's a fake chip.

You might be able to find some 3rd-party tools which don't care - but, obviously, they're not supported by ST.

Again, you should contact the board manufacturer for support.

And again, see:

Sure - if you successfully fit a genuine chip, then it is a genuine chip!

But is that less work than adding an ADC to a known-good board?

Also, remember that getting actual high-precision results takes more than just fitting a "high-precision" chip; it requires a lot of careful analogue design - does this board have that?

Can you even get a schematic?

ST resources are only dedicated to supporting genuine ST products. We are not committed to ensuring that clones/fakes products work properly with the firmware we provide.

As suggested by @Andrew Neil we recommend to purchase genuine products and purchase them from known and trusted distributors.

Good luck!
