How to attach debugger to an already running MCU ?

[HGate.2]

Hi,

I'm using STM32CubeIDE with a SEGGER J-Link connected to an STM32F7.

I manage to flash and debug the board but I can't find how to attach the debugger to the target without resetting it.

Thank you for your help.

You should describe the procedure you use. In gdb "att 1" should attach you to the first target.
