[C90LC D-Flash]

Hello All,

 

I am working on C90LC D-Flash of MPC560xB to implement a customized solution for EEPROM emulation.

I'am testing my product behavior after a power loss while there was a flash operation ongoing.

- If the power off occurs during an erase operation, at the next power on I get a core exception (IVOR2) at the first access to the corrupted flash address.

- If the power off occurs during a writing operation I have no exception at the next power on.

 

My question is :

Is it normal that there is no core exception if the writing operation is suspended by a shutdown ?

Knowing that I forced the shutdown at different points of writing operation (before and after setting and clearing MCR-EHV & MCR-PGM).

 

Regards,
