HCS12 checksum position

fabio_antonucci — Fri, 13 Sep 2019 09:36:36 GMT

Hello, I have an original hex file from a HCS12 (MC9S12DG256) and the related modified one, I also have calculated the checksum of the modified one.
In which point of the new hex file have I to write the SC inside the file that I will punt in the MCU?
Thx!

HI Fabio

Above screenshot is a generally description of hex file format, we can see checksum is at the last two bytes of each record.

If you have specific problem on your hex file, please check which IDE generates the hex file, you need check the IDE setting and contact the IDE producer for the specific issue

Have a great day,
Jun Zhang

Jun,

many thanks for your replay.

As far I understand there is no file checksum that as to be inserted in the hex file but each line has it's own CS.
Is it correct?

fabio,

NXP CodeWarrior can add checksum to its srecord file automatically after a successfully build. No need to add checksum file to project again.

As I know, Most IDE has the same features also.

Still, if you have doubt on other vendor's IDE, you need check the specific IDE producer or help manual.

Have a great day,
Jun Zhang
