    hello @Imen.D 

    Its successfully read the ST link because I have not updated version. Currently I have updated STM32 Cube Programmer and it is read all information from MCU.
    Thanks for your support. :)

    Hello @Himanshuparmar and welcome to the Community :)

    Check NRST pin connection.

    Try connecting in "Hot plug" mode and change the port number access.

    Via STM32CubeProgrammer CLI, you can use: STM32_Programmer_CLI -c port=SWD mode=HOTPLUG --shared

    (please refer to UM2237 for more details)

    Hello @Imen.D, thank you for the connecting.
    As you can see that the NRST Pin is open. I have also tried with "Hot plug" mode but the getting same error.
