STLink Debugger is not listed in Keil for NUCLEO-L55E

[Murat]

STLink Debugger is not listed in Keil for NUCLEO-L55E (Cortex M33) project, but if I open any other project for other STM32 Cores, I can see the STLink debugger in the "Debuggers" list.

It was working before, I have now a new setup and I cannot find the STLink option, so I cannot program/debug my code

Any recommendation?

Using a NUCLEO-L552ZE​ in Keil without issue.

Make sure you have the right drivers installed. That it's visible in Device Manager, and usable with STM32 Cube Programmer.

Make sure it's not connected with any other application when using in Keil.

Make sure you have the most current DLLs in the Keil/ST-LINK directory.

Hi Tesla,

I have been using MDK 5.25 version for legacy compiler support for existing projects, and when I upgrade the 5.38 it works well.

This is odd, I was using 5.25 in my previous setup too, it was working. Anyway, thank you for the answer.
