Hallo
I want calculate the Checksum over the whole range of a HCS12XDP512 Flash (including vector table). The Checksum should be placed at address 0xFFBEFE.
Is it possible to place the checksum within checksum area (checksum area: 0xE08000 to 0xFFBFFF).
Can I calculate the Checksum over more than one segment?

Code:
