Hello, I need to catch gpio interrupts while using NDK, so I added to the client.c the following (processors.wiki.ti.com/.../Configuring_Interrupts_on_Keystone_Devices)

1. #include <xdc/runtime/Error.h>
   #include <ti/csl/csl_gpio.h>
   #include <ti/csl/csl_gpioAux.h>

2. void gpio_isr_handler(UArg arg)
   {
   printf("GPIO interrupt!!!\n");
   }

3. Hwi_Handle myHwi;

   int init_gpio_interrupt_hwi(char pinNum, char intNum)
   {
   Int32 instNum = 0;
   Uint8 bankNum = 0;

   hGpio = CSL_GPIO_open(instNum);
   CSL_GPIO_setPinDirOutput (hGpio, pinNum);
   CSL_GPIO_setRisingEdgeDetect (hGpio,pinNum);
   CSL_GPIO_bankInterruptEnable (hGpio,bankNum);

   printf("Mapping GPIO%d (Event%d) to INT%d...\n",pinNum,pinNum+74,intNum);

   Hwi_Params hwiParams;
   Error_Block eb;

   Hwi_Params_init(&hwiParams);
   Error_init(&eb);

   // set the argument you want passed to your ISR function
   hwiParams.arg = 1;

   // set the event id of the peripheral assigned to this interrupt
   hwiParams.eventId = pinNum+74;

   // don't allow this interrupt to nest itself
   hwiParams.maskSetting = Hwi_MaskingOption_SELF;

   //
   // Configure interrupt intNum to invoke "gpio_isr_handler".
   // Automatically enables interrupt intNum by default
   // set params.enableInt = FALSE if you want to control
   // when the interrupt is enabled using Hwi_enableInterrupt()
   //

   myHwi = Hwi_create(intNum, gpio_isr_handler, &hwiParams, &eb);

   if (Error_check(&eb)) {
   // handle the error
   }

   return 0;
   }

4. int StackTest()

   {

   int rc;
   int i;
   HANDLE hCfg;
   CI_SERVICE_TELNET telnet;
   CI_SERVICE_HTTP http;
   NIMU_QMSS_CFG_T qmss_cfg;
   NIMU_CPPI_CFG_T cppi_cfg;

   init_gpio_interrupt_hwi(15,10);

   if (setupRm ())

   {
   NIMU_testLog ("Function setupRm failed\n");
   System_flush();
   goto main_exit;
   }

   ...

   I got the statement in console
   

   

   Then when I tried to set the interrupt using CodeComposer Registers it seems interrupt didn't work (my gpio_isr_handler didn't print the message)

   
   

   How can I achieve my goal: configure gpio interrupt while using NDK? All gpio interrupt examples I found are working standalone, so I think there's a collision between ndk interrupts and my interrupts.
