CC2640: CC2340 CCS default CCFG

Part Number: CC2640
Other Parts Discussed in Thread: CC2340R5

Hi,

we want to know what does CCS do during the 'ProgramDefaultCCFG'. we were able to program the chip through UART after 'ProgramDefaultCCFG', but after program, the CCFG seems changes by our code, and we are unable to communicate with CC2340 again through UART. it would be really helpful if we could know what does 'ProgramDefaultCCFG' do.

  • Hi, is there a way to make sure the CCFG is not changed after programing our code into the CC2340?

  • Hi,

    The ProgramDefaultCCFG script was part of an older SDK release. Please ensure you are on the latest SDK release available on Secure Resource. At the time of writing this, the latest SDK is the 6.41 SDK. Can you verify if this behavior is observed on the latest SDK?

    Best Regards,

  • Hi Jan, where I can find the default CCFG source code? we are using the latest SDK for sure, and we want to know what does the ProgramDefaultCCFG do. because we can only program the chip after 'ProgramDefaultCCFG'.

  • Hi,

    The ProgramDefaultCCFG code is implemented in a gel file that can be found as part of the CC23XX support files that were provided previously. Can you specify which CCS version you are using? The latest CCS version does not require these support files and does not contain the gel file either. However, if you are on the 6.41 SDK, there is now a different procedure for flashing a blank device. This procedure is detailed in the getting started section of the User's Guide. It consists of launching a target configuration for the CC2340R5, then while the target configuration is open, flashing the device. This prevents the need of programming the default CCFG.

  • Hi Jan, is there any document related to CCFG that I can learn how to use/config it?

  • Hello,

    There will be a section on the device TRM that will describe the CCFG in-depth. We currently have a draft version available on MySecureResource, but that draft may not have the CCFG section yet. For a timeline on when the final TRM or an updated draft will be ready, please reach out to your TI representative.

    Best Regards,
