All '0' in flash memory

[carlesls2]

Hello I have a question.

The '0' s instead of 0xFFFFFFFF in the memory is something that really occurs on the flash memory or it is a value that appear because the stm32cubeide is not able to read all the position of the memory, or in other words, the IDE is unable to confirm that the memory is empty.

 

 

Thanks a lot.

Hello @carlesls2 

First let me thank you for posting.

Could you please give more details about the scenario which led to this behavior.
And if possible can you share you binary file. You can send it via private message.

KR,

As I check the memory and the memory is being written on, I see that there are '0' on the upper parts of the memory.

Which STM32?

'L0 and 'L1 have an unusual FLASH which is erased to all- zeros, instead of the usual all-ones.
