I have a Nucleo-H723ZG board. The GPIO lock bits are set at reset so I cannot set up the ports. See Attached screenshot. I can run code just fine and the original demo code did toggle the LEDs.
Am I missing something here?

Since all of the GPIOA registers report 0xABFFFFFF, I'm more inclined to believe this is a debugger/IDE issue.

Hello @Niramas and welcome to the ST community,
I'm confused. You said:

The LEDs are toggling even the lock bits are set after reset?

The screenshot is not from the demo it is from our SW. Notice it is stopped at the reset vector though.

The demo came pre loaded on the device and is gone now.

The memory dump shows the same values.
