So it's losing connection to the device.
Does your application put the CPU to sleep, and/or disable or reconfigure the SWD pins?

Hi,
The application/code doesn't put the CPU to sleep . The flashing or debugging is using a ST-Link (a USB wire). In STM32CubeIDE , during debug mode , i am facing this issue . Could you explain the disable or reconfigure the SWD pins mean here ?
Thanks

The SWD lines (SWDIO and SWCLK) are on PA13 and PA14:
So, if your code does anything to PA13 and/or PA14, it will break the debug connection.
