how to change st-link firmware from V2 to v2-1?

[Fheid.1]

Hi all

I have St-link v2 and I am facing a problem for debugging Cortex M in stm32mp157-ev1.

I think it is because of the differences between HW Vesion and FW in keil document and my results.

In attachment image is mentioned stlink v2-1.

• Shall i use Stlink V2 instead of V2-1?
• How do I change my version of the Stlink from V2 to V2-1?

Best regards

STLink version cannot be changed. V2 and V2-1 are based on two different chips.

Hi @Fheid.1​ 

Your problem looks similar to this old post :

Can it help ?

Hi dear @Community member​ 

thanks for your attention, but it is not similar to my problem.

The stm32mp157-ev1 is supposed to come with the V2-1, perhaps you're using an older version of MDK, and need a current install with DLL and drivers.

Unfortunately your post isn't sufficiently illuminating about what you are seeing and what version of Keil you're using.

Perhaps include screen shot(s) from YOUR install rather than the working ones from the documentation.
