Hi I have a bin file for a ecu that I am working on. But I am having some trouble calculating the checksum so I can make changes. I was told to calculate the checksum the sum of all BYTES needs to be 0x00.
Can somebody explain what exactly this means?
Thanks
I read everything on that page but what does it mean to calculate the checksum the sum of all BYTES needs to be 0x00.
You have not told us exactly what "all BYTES" means. This might be a transmitted packet of information, but who knows?
If you absorbed the material in the article then you will understand that there are many different methods of calculating a checksum (countless, actually, and many are proprietary). Which particular checksum method is used by your gizmo?
