Dear 

 

We use an S32K144 MCU and play to check if the code is completeness when power on every time. Now we calculate CRC of checksum and save the value at then end of Flash. And Read every byte of flash of all the setting address when power on. Compare the saved checksum and new calculated checksum. But it cost too much time. About 40ms now. 

 

Do we have an hardware method to get the same purpose to check if the Flash are the same as Programed(No damaged)  

 

Thanks you very much.

 

Charles
