Blue pill (STM32F1) programs OK via Arduino IDE but not Keil. Chip ID:0x2BA01477

[IMumt.1]

I am trying to program STM32 Blue pill board using Keil, and it gives the following error: "Connection refused due to device mismatch; Device connected to debug unit is different from device selected for project target STMicroelectronics STM32F103C8." I am using ST-Link debugger for programming as it does not have on-board ST-debugger. The issue is that it reads chip ID:0x2BA01477, which, I have read on other forums, is the ID read when your board uses clone instead of real STM32F103C8T6. Still, I want to program it using Keil. When I program the same setup using Arduino IDE, it is gets programmed in a perfectly fine way. Is there any other way to resolve this error in Keil using the same board or there is no other option left but to replace the board?

I tried reading the serial number of st link using st-link utility and got this.

 

I was able to see a similar or the same serial number in keil however, now i only see "4".

I also tried to flash a blink file (compiled using arduino IDE) using st-link utility and was successful.

So are you using a genuine ST-Link, or a fake/clone?

Note that anything looking like this is a fake/clone:

 

Another one of the "benefits" (sic) of these fake/clone ST-Links is that do not have consistent pinouts - they can be different, even when bought from the same place!

Hello,

I will tell you my short history with microcontrollers.

I started with a Raspberry Pi bought around 2016. I made big projects with it, but there's no need a complete computer for most projects.

Around 2020, I tried Arduino. I thought it wasn't bad... but I soon found it had many limitations and errors.

And I heard about ST.

I bought a two blue pills (f103c8t6 and f103c6t6). In those days, the chips were STM32 originals.

I started to love this brand. Thousands of chips, you can select the features you need, 32 bits, fast, ... perfect.

I bought some f103c6t6 and lots of g030f6p6 with adapter boards. All working fine.

BUT THE PIRATES ARRIVED :(

I bought some blue pills more and began with programming problems. Bought on other sellers, but none original.

The solution was buying a nucleo board. I bought the NUCLEO F446RE for developing projects without limitations, and later make a board with a mcu adapted to project requirements.

 

So, my answer for your question is:

Replace the board and you won't waste as much time and money as I did.

Buying on official ST sellers is cheaper, faster and safer than big internet sellers.

I agree to your suggestion and I have borrowed a Nucleo board, from my friend, for experimentation. Anyways, xisco, thanks!

I think it might also have been suggested by others ... ?

Excellent choice!

:thumbs_up::clapping_hands:

Now please mark the solution.

 

PS

I don't think you ever answered this question:

Is that using an ST-Link (or any other SWD programmer), or the Arduino serial bootloader ?

If you were using the Arduino serial bootloader, that would explain why the Arduino IDE could program successfully.

I encountered the same problem today. I searched the community and found that it was because I bought a counterfeit chip.
But it can also be burned using ST-LINK. Just remove the √ sign from the options marked in the picture.
