TMS320F28379D: How to unify the firmware for both CPU1 and CPU2

Takayuki Miyazaki

Part Number: TMS320F28379D

Hi Experts,

Customer plans to use the same firmware code for both CPU1 and CPU2, and they would like to change peripheral configuration as follows. Therefore, customer would like to know how CPUx itself is able to know if it is CPU1 or CPU2. I mean, is there any useful flags/parameters for this ?

Can I have your Expert’s advice/comments on this, please?

If( “This firmware is running on CPU1” ){

InitGpio1();                                     // Initialize the shared GPIO pins (FILE: Gpio.c)

    InitAdca1();                                    // Initialize the ADC-A (FILE: Adc.c)

    InitEPwm1();                                  // Initialize the DAC-B (File: Dac.c)

    InitDacb1();                                    // Initialize the EPwm (FILE: EPwm.c)

}

Else{

InitGpio2();                                    // Initialize the shared GPIO pins (FILE: Gpio.c)

    InitAdca2();                                    // Initialize the ADC-A (FILE: Adc.c)

    InitEPwm2();                                  // Initialize the DAC-B (File: Dac.c)

    InitDacb2();                                    // Initialize the EPwm (FILE: EPwm.c)

}

Miyazaki,

you can use CPU1/CPU2 predefined symbol to make compile-time You can use. something like below.

#ifdef CPU1
    InitGpio1();                                     // Initialize the shared GPIO pins (FILE: Gpio.c)

    InitAdca1();                                    // Initialize the ADC-A (FILE: Adc.c)

    InitEPwm1();                                  // Initialize the DAC-B (File: Dac.c)

    InitDacb1();                                    // Initialize the EPwm (FILE: EPwm.c)

#elif defined(CPU2)

    InitGpio2();                                    // Initialize the shared GPIO pins (FILE: Gpio.c)

    InitAdca2();                                    // Initialize the ADC-A (FILE: Adc.c)

    InitEPwm2();                                  // Initialize the DAC-B (File: Dac.c)

    InitDacb2();                                    // Initialize the EPwm (FILE: EPwm.c)

#endif

Hi Santosh,

Thanks for your clarification. That's simple and makes sense. I'll share this with our customer.

Best regards,

Miyazaki
