Cortex M33 not detecting in STM32MP257F-DK using ST-link

Hi

I am trying to program the Cortex M33 of STM32MP257F-DK dev board using CubeIDE. I have generated the code in Cube IDE. The debugger failing to program as the board not responding.

Following are my debug settings:

Again I tried using STM32 Cube Programmer, no luck.

But its able to detect Cortex A35 using USB DFU mode and able to flash Linux into sd card.

But the MCU is unable to detect.

I tried boot settings in Development Mode 0011. Also tried 0001 and 0000. Same issue.

Can anybody let me know where I am going wrong?
