Getting ST-LINK error (DEV_TARGET_NOT_HALTED) while connecting my device with STM32CubeProgrammer

[PPate.5]

I am facing an issue while connecting my STM32H745 device with STM32CubeProgrammer.

I tried various suggestions posted here by different users for similar questions. However, still, I am not able to connect my device with CubeProgrammer

Below are different ways I tried already

1. Placed Boot pin to High state before power-up. So that STM32 boots from system memory.
2. Also, tried to connect the device with CubeProgrammer by setting "Under Reset" mode in the CubeProgrammer
3. Tried with lower clock speed 8000 in the CubeProgrammer

Let me know what else I can try to overcome this issue

hello

Forcing BOOT0 high only during the initial power-up did not work.

Forcing NRST low at various points in the programming cycle also did not work. If I held it too long I would get TARGET_HELD_IN_RESET, and any time shorter I would get DEV_TARGET_NOT_HALTED.

Thanks for the suggestion.

I forgot to add this one to my list. I already tried this suggestion as well but it did not work out.
