AM2634: GPIO interrupt configurations

I configure the gpio19 in pin interrupt mode 

and Interrupt enable by 

   HwiP_Params_init(&hwiPrms);
    hwiPrms.intNum = CSLR_R5FSS0_CORE0_CONTROLSS_INTRXBAR0_OUT_19;
    hwiPrms.callback = &GPIO_muxIsrFxn;
    hwiPrms.args = (void *) pinNum;
    retVal = HwiP_construct(&gGpioHwiObject, &hwiPrms);

call back function isn't hit

static void GPIO_muxIsrFxn(void *args)
{
    /*
     * Handle pin interrupt - This is pulse interrupt. No need to clear status
     *
     */
//    DebugP_log("Interrupt Generated!!\r\n");

    uint32_t    pinNum = (uint32_t) args;
       uint32_t    bankNum =  GPIO_GET_BANK_INDEX(pinNum);
       uint32_t    intrStatus, pinMask = GPIO_GET_BANK_BIT_MASK(pinNum);

       /* Get and clear bank interrupt status */
       intrStatus = GPIO_getBankIntrStatus(gGpioBaseAddr, bankNum);
//       GPIO_clearBankIntrStatus(gGpioBaseAddr, bankNum, intrStatus);
       gGpioIntrDone2++;
       DebugP_log("Interrupt Generated!!\r\n");
       /* Per pin interrupt handling */

}

Can you just cross check what wrong i did

Can you try changing  hwiPrms.intNum  to GPIO_INT_XBAR_GPIO_MUX_19, and let me know if it works.

Thanks

GPIO_INT_XBAR_GPIO_MUX_19 is not working for me CSLR_R5FSS0_CORE0_INTR_GPIO_INTRXBAR_OUT_14 is working,

Am2634 has 144 interrupt enabled gpio So kindly let me know how to configure 20 Pins as interrupts and how to manage call back function for these interrupts?

There are only 4 GPIO interrupts mapping to VIM0 then CPU core. The interrupt numbers are 144, 145, 146, and 147.  

CSLR_R5FSS0_CORE0_INTR_GPIO_INTRXBAR_OUT_14 is --> 144

What are the interrupt numbers used for other GPIO interrupt events in your code?

As per CSLR_R5FSS0_CORE0_INTR_GPIO_INTRXBAR_OUT_14 142 is interrupt number

but the question is can we define 20 GPIO interrupts on this MCU/SDK? 

Yes, you can define any number of GPIO interrupts in your application. But as mentioned in TRM, there are only 4 VIM channels assigned to all the GPIO interrupts.

You can have one ISR for GPIO interrupts or up to four ISR for GPIO interrupts.

1. The interrupt number is 142 if GPIO_INT_XBAR_VIM_MODULE0_0 is selected for XBAR instance 

2. The interrupt number is 143 if GPIO_INT_XBAR_VIM_MODULE0_1 is selected for XBAR instance 

Do you have some sample code for multiple gpio interrupts or let me know how to update the gpio_input_interrupt_am263x-cc_r5fss0-0_nortos_ti-arm-clang project for multiple interrupts 

Hi Vikas,

I don't have a working example for multiple gpio interrupts.

Any document to configure multiple GPIO interrupts in AM2634

Hi Vikas,

I am working on a CCS project for handling interrupts from multiple GPIO pins, and will post the project after tested.

Thanks Wang and Appreciate your efforts,

I also try in same way and I able to configure 4 interrupts only, but i need more than 4 interrupts

because it has 4, GPIO_INT_XBAR_VIM_MODULE0_0/1/2/3 only So can we configure 4 interrupts only? 

void Drivers_gpioIntXbarOpen()
{
/*
* GPIO INTERRUPT XBAR
*/
SOC_xbarSelectGpioIntrXbarInputSource(CSL_GPIO_INTR_XBAR_U_BASE, GPIO_INT_XBAR_VIM_MODULE0_0, GPIO_INT_XBAR_GPIO_MUX_21);
SOC_xbarSelectGpioIntrXbarInputSource(CSL_GPIO_INTR_XBAR_U_BASE, GPIO_INT_XBAR_VIM_MODULE0_1, GPIO_INT_XBAR_GPIO_MUX_43);
SOC_xbarSelectGpioIntrXbarInputSource(CSL_GPIO_INTR_XBAR_U_BASE, GPIO_INT_XBAR_VIM_MODULE0_3, GPIO_INT_XBAR_GPIO_MUX_45);
}
 

In my project I need to use more than 20 GPIO interrupts So please let me know how to configure 20 interrupts,

I believe Am2634 is most powerful MCU and its has the capability to handle all the GPIO interrupts

You can use GPIO bank interrupt. The 16 GPIO pins in the same bank will share the same interrupt number and interrupt ISR. The IRS can handle the interrupt source by reading the GPIO interrupt status register. 

I haven't got chance to try, but I think this way should work.

Yes, I'm also thinking in a same way and try also, but its not working (This is main problem)

I configure 5 GPIOs on same bank with same interrupt number, while testing it's giving interrupt  on the last pin not on all pins,

requesting to test on your side

Could you please send the code

Great, I found my mistake also

I passed hwiPrms.args     = pin number instead of bank number while configuring the Bank interrupts
