Hi @Ashu123 ,

If you still face an issue to connect your boards with STM32CubeProgrammer, I suggest the following:

  • try to connect with the mode set to "Under Reset"
  • perform a firmware upgrade.

You find some more recommendations in the article How can I connect to my STM32 evaluation board using STM32CubeProgrammer.
