Unable to access Internal flash Bank 2 on Nucleo H753Zi board.

Any writes, erases or reads to flash range greater than 0x8100000 fails. When I inspect the region via Memory browser in STM32Cube IDE all memory beyond 0x8100000 appears as a "?" indicative that a read is not being allowed. Being new to this controller and STM family of devices , I'm not sure what configuration I am missing. Can you please provide any hints or tips

    Never mind. I fixed the issue. It was a bug in my code where I was erasing a sector out of range (which in turn caused the Flash to lock up and wouldn't reset even after a power cycle).

    Further I was not cleaning my DCache before programs
