Failed to execute MI Command Error

[Thenuk__a]

Hy!

I'm new to STM32. I'm currently using STM32F103C8T6 board, and it give MI command error (image attached). I have tried using STM32 programmer as well to fix it. Still couldn't. How can i fix this?

Welcome to the world of STM32!

Do you have any experience with any other microcontroller(s) ?

What board, exactly ?

And what ST-Link are you using?

The important part of the message is here:

So it's not seeing your STM32.

• Is the target properly connected?
• Is the target properly powered?

I have used only Arduino. The board i'm using is STM32F103C8T6. I'm using ST-Link V2.

That's just the part number of the chip - you need to say what board you're using

That's a clone - not a genuine ST product.

Check your connections very carefully - different clones have different pinouts!

Thanks. Changed the ST link and it worked

Excellent - please mark that as the solution
