I am trying to use the STM32CubeProgrammer API to program and read a STM32G491.
so that we can use it in our programming solution. (We write a CRC of the application so that a bootloader can validate it. )
The problem is that the readout of memory does not always work correctly.
I am running the Example1 project with the API.
(On a nucleo-g491RE demo board)
This does a read after a sector erase.
this results in the same data readout as before the sector erase.

When I read the data with the STM32CubeProgrammer application after this it does read as erased.
So what can I do to get a accurate readout of the memory.
