Hi !


During flash erase/program operation error can happens and it seems to me it is not recoverable.

Even reading of this area of memory cause Hardfault.

Only erasing of whole flash can suppress it.


Does it possible to detect this kind of memory areas and erase only several Flash sectors ?


Can this problem be similar to one what is explained in errata ?
