Hello All,
We are using STM32h7A3 microcontroller in our project. When we dump the simple uart code and reset , it is giving the results until power off condition. After power off condition , ST link unable to detect the MCU until erase FLash and download code again using STM32 cube programmer.
Attached the sch for reference. Any suggestion in hardware , firmware side.
Anybody have cubemx setting for this MCU , please share .

The chip has to be powered in order to function. The SWD connector does not provide power.

But STM32CubeProgrammer uses st-link in order to communicate with the chip. If it's unable to detect, how is it programming it?
