Hello,

How can I attach to running microcontroller in the STM32CubeIDE?

The IAR has the Attach to running target function. The STM32CubeIDE have not this function.

Create a Debug Configuration with 'Reset behaviour' set to 'None' and 'Download' disabled:

#AttachToRunningTarget

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.
