CCS/TMS320F28388D: TMS320F28388D

Part Number: TMS320F28388D

Tool/software: Code Composer Studio

Hello

I am new to developing Dualcore. (TMS320F28388D)

CPU1 transferred the GPIO authority of CPU2 and completed LED Blinking with Timer.

However, it is not giving CPU2 SCI (or other function) authority.

I don't know if you refer to Example

Are there any commands (functions) that give CPU2 peripheral privileges?

Simply, just giving the GPIO authority doesn't work?

CPU1 GPIO Initialize Code :

    Device_initGPIO();

    GPIO_setPadConfig(DEVICE_GPIO_PIN_LED1, GPIO_PIN_TYPE_STD);
    GPIO_setDirectionMode(DEVICE_GPIO_PIN_LED1, GPIO_DIR_MODE_OUT);

    GPIO_setPadConfig(DEVICE_GPIO_PIN_LED2, GPIO_PIN_TYPE_STD);
    GPIO_setDirectionMode(DEVICE_GPIO_PIN_LED2, GPIO_DIR_MODE_OUT);

    // GPIO28 is the SCI Rx pin.
    //
    GPIO_setMasterCore(28, GPIO_CORE_CPU2);
    GPIO_setPinConfig(GPIO_28_SCIA_RX);
    GPIO_setDirectionMode(28, GPIO_DIR_MODE_IN);
    GPIO_setPadConfig(28, GPIO_PIN_TYPE_STD);
    GPIO_setQualificationMode(28, GPIO_QUAL_ASYNC);

    //
    // GPIO29 is the SCI Tx pin.
    //
    GPIO_setMasterCore(29, GPIO_CORE_CPU2);
    GPIO_setPinConfig(GPIO_29_SCIA_TX);
    GPIO_setDirectionMode(29, GPIO_DIR_MODE_OUT);
    GPIO_setPadConfig(29, GPIO_PIN_TYPE_STD);
    GPIO_setQualificationMode(29, GPIO_QUAL_ASYNC);

    //
    // Configure CPU2 to control the LED GPIO
    //
    GPIO_setMasterCore(DEVICE_GPIO_PIN_LED2, GPIO_CORE_CPU2);

CPU2 SCI Peripheral Init Code

    //
    // Initialize SCIA and its FIFO.
    //
    SCI_performSoftwareReset(SCIA_BASE);

    //
    // Configure SCIA for echoback.
    //
    SCI_setConfig(SCIA_BASE, DEVICE_LSPCLK_FREQ, 9600, (SCI_CONFIG_WLEN_8 |
                                                        SCI_CONFIG_STOP_ONE |
                                                        SCI_CONFIG_PAR_NONE));
    SCI_resetChannels(SCIA_BASE);
    SCI_resetRxFIFO(SCIA_BASE);
    SCI_resetTxFIFO(SCIA_BASE);
    SCI_clearInterruptStatus(SCIA_BASE, SCI_INT_TXFF | SCI_INT_RXFF);
    SCI_enableFIFO(SCIA_BASE);
    SCI_enableModule(SCIA_BASE);
    SCI_performSoftwareReset(SCIA_BASE);
