AM2632: GPIO interrupt

Tool/software:

Dear TI Support Team,

I hope this email finds you well.

I am currently working on configuring a GPIO interrupt triggered by a rising edge. In the existing example code, the implementation uses GPIO-bank-INTR. However, I need to configure a single GPIO pin to trigger its own dedicated interrupt instead of sharing a bank-level interrupt.

Could you kindly clarify the following questions?

1. How should I configure a single GPIO to map to a unique interrupt (instead of a bank)?

2. In SysConfig, there is a "GPIO INT XBAR" section. I would like to understand:

   • How do the XBAR Output and XBar Instance parameters correspond to each other?

3. Could you provide guidance on the interrupt configuration steps in the code (e.g., registering ISRs, enabling interrupts, etc.)?

4. I have also looked at the link description below and I would like to know how gPepiaPinIntrNum and gPepiaBankIntrNum are configured and their corresponding relationship with syscfg                          software-dl.ti.com/.../DRIVERS_GPIO_PAGE.html

   void gpio_bank_interrupt_init(void)
   {
       int32_t         retVal;
       uint32_t        pinNum = gGpioPinNum, bankNum;
       HwiP_Params     hwiPrms;
    
       bankNum = GPIO_GET_BANK_INDEX(pinNum);
    
       /* Interrupt setup */
       GPIO_setDirMode(gGpioBaseAddr, pinNum, GPIO_DIRECTION_INPUT);
       GPIO_setTrigType(gGpioBaseAddr, pinNum, GPIO_TRIG_TYPE_RISE_EDGE);
       GPIO_bankIntrEnable(gGpioBaseAddr, bankNum);
    
       /* Register bank interrupt */
       HwiP_Params_init(&hwiPrms);
       hwiPrms.intNum = gGpioBankIntrNum;
       hwiPrms.callback = &GPIO_bankIsrFxn;
       hwiPrms.args = (void *) pinNum;
       retVal = HwiP_construct(&gGpioHwiObject, &hwiPrms);
       if(SystemP_SUCCESS != retVal)
       {
           DebugP_assert(FALSE);
       }
   }
   
   void gpio_pin_interrupt_init(void)
   {
       int32_t         retVal;
       uint32_t        pinNum = gGpioPinNum, bankNum;
       HwiP_Params     hwiPrms;
    
       bankNum = GPIO_GET_BANK_INDEX(pinNum);
    
       /* Interrupt setup */
       GPIO_setDirMode(gGpioBaseAddr, pinNum, GPIO_DIRECTION_INPUT);
       GPIO_setTrigType(gGpioBaseAddr, pinNum, GPIO_TRIG_TYPE_RISE_EDGE);
       GPIO_bankIntrEnable(gGpioBaseAddr, bankNum);
    
       /* Register pin interrupt */
       HwiP_Params_init(&hwiPrms);
       hwiPrms.intNum = gGpioPinIntrNum;
       hwiPrms.callback = &GPIO_pinIsrFxn;
       hwiPrms.args = (void *) pinNum;
       retVal = HwiP_construct(&gGpioHwiObject, &hwiPrms);
       if(SystemP_SUCCESS != retVal)
       {
           DebugP_assert(FALSE);
       }
   }

My requirement is r5fss1-0, PR0_PRU0_GPIO4，pin interrupt。

Please provide me with specific syscfg and gPepiaPinIntrNum。

Thank you for your time and support!

Best regards,
