GPIO Interrupt error

Hi Community,

Am working on imx7 dual board. Am having problem with configuring GPIO falling edge interrupt. Could someone help me with this problem?
Am using this for FreeRTOS
Here is my configuration.
1. pins.c - in this file, I have configured GPIO 63 in alt 5 mode.

gpio_config_t gpio_Unknown1 = {
"SODIMM 63", /* name */
&IOMUXC_SW_MUX_CTL_PAD_ENET1_RGMII_RD2, /* muxReg */
5, /* muxConfig */
&IOMUXC_SW_PAD_CTL_PAD_ENET1_RGMII_RD2, /* padReg */
IOMUXC_SW_PAD_CTL_PAD_ENET1_RGMII_RD2_PS(2) | /* padConfig */
IOMUXC_SW_PAD_CTL_PAD_ENET1_RGMII_RD2_PE_MASK |
IOMUXC_SW_PAD_CTL_PAD_ENET1_RGMII_RD2_HYS_MASK,
GPIO7, /* base */
2

2. in board.h - I have added these lines - GPIO_Unknown1 is my config for port 63

#define BOARD_GPIO_UNKNOWN1_RDC_PDAP rdcPdapGpio7
#define BOARD_GPIO_UNKNOWN1_CONFIG (&gpio_Unknown1)
#define BOARD_GPIO_UNKNOWN1_IRQ GPIO7_INT15_0_IRQn
#define BOARD_GPIO_UNKNOWN1_HANDLER GPIO7_INT15_0_Handler

3. and in main.c am trying to toggle other port.

int readpin63;
readpin63 = GPIO_ReadPinInput(gpio_Unknown1.base, gpio_Unknown1.pin);

if (readpin63)
{
GPIO_WritePinOutput(gpio_Unknown2.base, gpio_Unknown2.pin, 1);
vTaskDelay(blinkingInterval);
GPIO_WritePinOutput(gpio_Unknown2.base, gpio_Unknown2.pin, 0);
vTaskDelay(blinkingInterval);

Am I missing something or the way am doing is wrong?

Hi Prady

for gpio interrupt example one can look at ../demo_apps/blinking_imx_demo/gpio_ctrl.c

Windows Installer: i.MX 7Dual/Solo FreeRTOS BSP for Cortex-M4

Pay attention to function NVIC_EnableIRQ(BOARD_GPIO_KEY_IRQ_NUM),
BOARD_GPIO_KEY_IRQ_NUM can be found in board.h.

Best regards
