STLINK_V3_SET not connect to STM32H745

Hello,

I have STM32H7 based custom board. I am using the STLINK_V3_SET for programming to custom board. I am using the SWD port

of STLINK. But when we try to programming from[STM32CUBEIDE M7 get programming and when try to programmed through the M4 it gets

stuck. When we try to to programming through the STM32CUBEPROGRAMMER the programming get done but no output is coming. We try the simple LEWD

blinking programmed. I need your guidance.
