CCS checksum output

Hello, 

Anybody know the CCS how to output or display checksum value in below image?  thanks very mcuh.

  • You should be able to calculate the checksum once you are in a debug session. If you open menu Tools->On-Chip Flash in a debug session, you can click on "Calculate Checksum" there, and it will then populate the values.

  • Hi,AartiG

    Sorry for I'm unresponsive comfirm your answer, it's correct.  But now I have another quessiton is how to calculate option segment checksum of Flash , example: I want to caculate Flash A and B segment only then how I to do? thanks  very mcuh.

    Sorry but there is no option in the tool to calculate the checksum for each flash sector, it is only calculated on the entire Flash.

  • Hi AartiG or other Gurus out of there,
    Did you notice that this button "Calculate Checksum" is no longer available in the latest version CCS 6.01. I searched several times in On-Chip Flash screen but could not find it. Do you know why and also please advise where it is now or how to calculate checksum for code section for flash? Many thanks!
  • Harry,

    The "Calculate Checksum" button is available in CCS 6.0.1 and CCS 6.1.0. Here is a screenshot from my system.

    Which device are you connecting to?

  • Hi AartG,

    Thanks for your prompt reply! Now I realized that this is probably not related to CCS version. I'm using F28377D and the button "Calculate Checksum" is nowhere to e found,  as shown in the attached screenshot. But if I connect it to an older device F28069, it would show up fine.

    The question now is, how to get it to work for F28377D?

    I don't see it for the F28377D device either. It must be something device specific that dictates whether this feature exists in the on-chip flash tool or not. I would suggest asking in the C2000 forum as the experts there should able to comment further.

  • All,

    We do not currently support checksum calculation for F28377D devices. The checksum calculation feature is only available on some C2000 devices, mostly on older Flash technology.

    For F28377D, we do support ECC and Flash based verification during Program Load.

    Thanks,
    Ricky
