    Give more detail on that - I don't see it in the screenshot provided.

    But what the screenshot does show is that your target has no power:

    Hi @claudenesta 

    This is normal. STM32MPU product doesn't support flashing through ST-LINK

    You might use USB boot. 

    Check-out STM32MP257x-EV1 - stm32mpu

    @Olivier GALLIEN 

    Thank you for your feedback, but what I mentioned early is running the code through the board using STM32CubeIDE, about flashing is already done with stm32mp2-openstlinux-6.6-yocto-scarthgap-mpu-v24.11.06 Starter package, is where I have used USB boot mode. 

    see the screenshot below:

    And I was thing that it is because of in STM32Cubeprogrammer does not find the STM32 Target to be connected.

    I think its clear now.
