CCS/TMS320F28379D: SCI MODE burn fail by C2Prog

Part Number: TMS320F28379D

Tool/software: Code Composer Studio

Hi,

I'd like to burn program by serial interface(SCI MODE), please refer to below figure 1.

When I pull up emulator and set GPIO72 and GPIO84 as SCI launch, burn program by C2Prog. There is a error warning which is “Connecting with target (autobaud)...  failed (no response)!”. Please refer to below figure 2.

Could you help to check what result in burning fail?

Thanks,

Walsh

    Per default, the 2837x MCUs use GPIO84/85 for SCI Boot communications. If you are working with a TMS320F28379D Launchpad or controlCard, then you are likely connected to GPIO42/43 or GPIO28/29, respectively, and hence there is no response to C2Prog's transmissions . Please double-check.

    Hi CodeSkin,

    Thanks, You are right. The reason of burning fail have been found that the default of SCI boot use GPIO84/85 for communication.
    But our product use GPIO28/29.
    Because our hardware is fixed, we don't want to modify the SCI schematic. Is there any way could change SCI boot to SCI boot1 (use GPIO28/29 for SCI Boot communication)? Could this be done by modifying software?
    Could you kindly help to advise detail method?

    Thanks,
    Walsh

    Thanks for the update. To be using GPIO28/29 for SCI Boot you would need to program the MCU OTP accordingly, and you would also need to obtain a custom C2Prog configuration from us. Feel free to contact us directly to discuss further (info@codeskin.com).
