STLINK-V3SET allows programming but not debugging

[Ans]

I've an STLINK-V3SET and while trying to connect with my board, it does detect the chip but I'm unable to debug. Works fine with stm32 programmer but I'm unable to debug program on stm32 cube ide.

Connections:

STLINK -- Board

GND --> GND

DIO  --> SWDIO

CLK --> SWCLK

Vcc --> V+ 

OS: Windows 10

Stm Chip: STM32L496ZG

Hello @Ans ,

Please share your error message or attach a screenshot that will help to understand your issue.

In Debug Configuration: Try change the Reset behavior type to “Connect Under Reset”.

I recommend you this article How to solve debugger connection issues, which describes the ways to fix debugger connection issues, and help you in debug configuration.
