Hi,

i have generated hex file for a particular project. The controller used is stm8s003f3. My question is regarding checksum. I'm not familiar with checksum. How can i add checksum to this hex file.? How can i determine the type checksum and its value? Please let me know in detail about checksum. I'm using STVD and STVP for development purpose. Any help would be appreciated......

#stm8 #checksum

Hello,

it depends on what compiler you are using.

For the Cosmic compiler, the checksum is calculated by the linker and can be verified by simply adding a couple of lines in your application, like this:

  if (_checksum())

    abort();

More details in the manual.

Regards,

Luca

hi,

Thanks for the help..

yes i'm using cosmic compiler. How can i determine the type of checksum in that case? Is it possible to add checksum by enabling readout bit (in ROP)using STVP. I have seen such a provision in STVP. I'm not sure whether its a right or not

Regards.
