Can not connect to target! stm32g030f6p

I faced to this problem while working with UARTa USB-to-TTL adapter I connected to the UART pins of my STM32G030F6 for working UART protocol and built the firmware using STM32CubeIDE. However, after doing this, my ST-Link V2 can no longer detect the STM32G030F6. What could be causing this issue?

Welcome @doniyor_khalilov, to the community!

Assuming that the STM32G030F6P6 on this board from an Asian manufacturer is not a clone, you would also have to connect NRST to the ST-LINK. If you have programmed a low power mode in the STM32G030, the easiest way to reach the target is with Connect under Reset.

Hope that helps?
