Here is my code

    CyU3PGpioSimpleConfig_t gpioConfig;
   
    gpioConfig.outValue = CyFalse;
    gpioConfig.inputEn = CyFalse;
    gpioConfig.driveLowEn = CyTrue;
    gpioConfig.driveHighEn = CyTrue;
    gpioConfig.intrMode = CY_U3P_GPIO_NO_INTR;
   

    CyU3PDeviceGpioOverride(17, CyTrue);
    CyU3PGpioSetSimpleConfig(17, &gpioConfig);
    CyU3PGpioSimpleSetValue(17       , CyTrue);     
 

In this way, I can not set GPIO17(CTL0) to high. I just test it with DVK. The pin only connect to oscilloscope.

Thanks

Hi,

It should work normally.

I am assuming that you are initializing the GPIO module before calling the code that you pasted here.

GPIO module can be initialized as follows:

/* Init the GPIO module */
        gpioClock.fastClkDiv = 2;
        gpioClock.slowClkDiv = 0;
        gpioClock.simpleDiv = CY_U3P_GPIO_SIMPLE_DIV_BY_2;
        gpioClock.clkSrc = CY_U3P_SYS_CLK;
        gpioClock.halfDiv = 0;

        /* Initialize Gpio interface */
        apiRetStatus = CyU3PGpioInit(&gpioClock, NULL);

Are you saying that it is not working only when you configure GPIF II in 32-bit mode. or it is not working at all for you. Please let me know.

Thanks,

sai krishna.

Are you seeing any of these APIs returning some error code?.

Thanks,

 I only modify this function in GpioApp project.  GPIO21 work prefect and  GPIO17 always 0.  Here is serial port output:  CyU3PGpioInit failed before output, error code = 67

Thanks

It worked. The 38-MIC-BRK-2 board is not pin to pin connect. I tested wrong pin.

Thanks
