TDA2HG: TDA2XX linux VSDK0305 IPU2 GPIO interrupt

my board boot as linux target, 

I want make a gpio interrupt on M4[ipu2], 

GPIO is GPIO2_6.

SDK: PROCESSOR_SDK_VISION_03_05_00_00.

my code

//gpio2_6
#define gpio_pin    6   //14//6 //14// //gpio2-6
uint32_t gpio_base_address = SOC_GPIO2_BASE;
uint32_t interrupt_num     = 52;//30//26;//51//52//29;//6;

#define IRQ_XBAR_CPU_ID         CSL_XBAR_IRQ_CPU_ID_IPU1
#define IRQ_XBAR_INST_NO        CSL_XBAR_INST_IPU2_IRQ_52//CSL_XBAR_INST_IPU1_IRQ_33
#define IRQ_XBAR_INDEX          CSL_XBAR_GPIO2_IRQ_1//CSL_XBAR_DSP1_IRQ_MMU0


//isr thread
void gpioIsr(void *arg)
{
    Vps_printf("I");
    //GPIOPinIntDisable(gpio_base_address, GPIO_INT_LINE_1, gpio_pin);   //GPIO2_6_PD int
#if 1
    uint32_t gpio_pin_value;//,cam4_pin_value = 6;

    /*Disable interrupt*/
    GPIOPinIntDisable(gpio_base_address, GPIO_INT_LINE_1, gpio_pin);   //GPIO2_6_PD int
    /*Read pin*/
    gpio_pin_value = GPIOPinRead(gpio_base_address, gpio_pin);
    GPIOPinIntClear(gpio_base_address, GPIO_INT_LINE_1, gpio_pin);
    printf( "I\n");
     /*Enable interrupt interrupt*/
    GPIOPinIntEnable(gpio_base_address, GPIO_INT_LINE_1, gpio_pin);
#endif   
}
int cam_intb_init(void)
{
//m4pid0
/*Configure interrupt controller*/ 
BspOsal_irqXbarConnect(52 /*CSL_XBAR_INST_IPU2_IRQ_52*/,CSL_XBAR_GPIO2_IRQ_1);
BspOsal_registerIntr(interrupt_num,gpioIsr,(void *) 0);
GPIOPinIntDisable(gpio_base_address, GPIO_INT_LINE_1, gpio_pin);
#if 0 
/*Enable GPIO*/
GPIOModuleEnable(gpio_base_address);
/*Configure and enable debouncing feature*/
GPIODebounceTimeConfig(gpio_base_address, 0xFF);
Vps_printf("GPIODebounceTimeConfig\n");
GPIODebounceFuncControl(gpio_base_address, gpio_pin,
GPIO_DEBOUNCE_FUNC_ENABLE);
Vps_printf("GPIODebounceFuncContro\n");
#endif
GPIOIntTypeSet(gpio_base_address, gpio_pin,GPIO_INT_TYPE_FALL_EDGE); 
Vps_printf("GPIOIntTypeSet\n");
/* Set pin direction as input*/
GPIODirModeSet(gpio_base_address, gpio_pin, GPIO_DIR_INPUT);
Vps_printf("GPIODirModeSet\n");
/*Clear interrupt*/
GPIOPinIntDisable(gpio_base_address, GPIO_INT_LINE_1, gpio_pin);
Vps_printf("GPIOPinIntDisable\n");
GPIOPinIntClear(gpio_base_address, GPIO_INT_LINE_1, gpio_pin);
Vps_printf("GPIOPinIntClear\n");

/*Enable interrupt*/
GPIOPinIntEnable(gpio_base_address, GPIO_INT_LINE_1, gpio_pin);
Vps_printf("GPIOPinIntEnable\n");


return 0;

}

In the above code, gpio2_6 is configured as interrupt_num=52 and gpio_pin=6. When gpio2_6 is pulled down externally, an interrupt can occur, but with the following exception, the log is thrown as follows

    When gpio2_6 is pulled down externally, hrow the following exception log：

Hi,

can you make sure you have disabled those gpio's in Linux, see this post for details:
