How to protecting *.prm file using processor expert?

Hi. I'm working using MC9S08DZ32 with processor expert(PE).

I make checksum for code crc in prm file as follow.

CHECKSUM

CHECKSUM_ENTRY

METHOD_CRC_CCITT

OF READ_ONLY 0x7C00 TO 0xFFFD

INTO READ_ONLY 0xFFFE SIZE 2

UNDEFINED 0xFF

END

But auto generated prm file removes above code.

How to protecting my checksum code?

One solution is freeze generate code but If I miss that when modify PE, code releases without code crc.

Please let me know awesome solution.

Thanks.

Hello,

You can use the Generate PRM file property in the CPU - Build Option tab. Open the Component Inspector of the CPU in your project, select the Build Options tab, set the value of the Generate PRM file to no. The PRM file will not be re-generated, i.e. you can modify it.
