Cannot connect STLINK Utility to NUCLEO-L552ZE-Q

Hello, I bought a NUCLEO-L552ZE-Q and tried to connect with STLINK Utility . But STLINK Utility rejects.

08:57:29 : ST-LINK SN : 066CFF505352716587121640
08:57:29 : V2J37M26
08:57:29 : Connected via SWD.
08:57:29 : SWD Frequency = 4,0 MHz.
08:57:29 : Connection mode : Connect Under Reset.
08:57:29 : Debug in Low Power mode enabled.
08:57:29 : Can not connect to the target!
08:57:33 : Unexpected error

I used the lastest ST-LINK Utility v4.6.0.0

Connection other boards, like STM32F4 Disco or STM324R9 Disco worked fine. Therefore STLINK Utility is basicly working

Additional strange is, that the NUCLEO-L552ZE-Q is working fine with CubeID. Programming and debugging is possible.

Therefore, at the moment, only the combination NUCLEO-L552ZE-Q + ST-LINK Utility isn't working.

I used the NUCLEO-L552ZE-Q out of the box. (No jumper modified)

Any ideas ?

The ST-Link Utility is a Windows only tool and still active, but the world was requesting tools for all platforms.

With the STM32CubeProgrammer STMicroelectronics therefore provides a multi-platform tool (Windows/Linux/MacOSX) for all recent and newer STM32, which also contains a CLI. You can easily replace the CLI statements in your scripts by the new ones.

Hello @FKaes.1​ ,

Welcome to the STM32 Community :smiling_face_with_smiling_eyes:

Are you able to connect and program it through STM32CubeProgrammer ?

Hello @Imen DAHMEN​ 

>>Are you able to connect and program it through STM32CubeProgrammer ?

yes, I downloaded STM32CubeProgrammer and it is working.

Is ST-Link Utility obsolete ?

Because I'm using ST-LINK CLI in a toolchain and therefore would like to keep it.

I aslo not understand, why only L5 is not working.

Hi @Peter BENSCH​ 

thanks to your answer. I will try to do this.

It would be nice, if STM can add a note at the ST-Link Utility page that is probably fails with new devices and direct to the new tool.

At least, before I created this ticket, I searched the internet and didn't find something to this topic.
