There is no breakpoint in the code

I am now able to connect to the target, found out my debugger is faulty. But, still facing problem after programming the controller. The program is simple LED toggle. I have checked the power supply configuration HAL_PWREx_ConfigSupply(PWR_DIRECT_SMP...

I am first trying to connect it to stm32 cube programmer

I am using external STLink V2 programmer connecting SWDIO, SCLK and GND
