Hello Everyone
Now I want to add a gpio interrupt test code into Platform SDK.
And all is run well (Coding/Compiling/Start Runing), but when run time with doing GPIO interrupt there is no response.
Detail:
1, source code in ../sdk/drivers/gpio/test/gpio_interrupt_test.c
#include "sdk.h"
#include "gpio/gpio.h"
#include "core/interrupt.h"
#include <stdio.h>
#define GPIO5_ICR1 ((uint32_t *)(0x20ac00c))
#define GPIO5_IMR ((uint32_t *)(0x20ac014))
#define GPIO5_PIN10 (10)
//globals used for gpio_irq_test
unsigned int gpio_irq_served;
void gpio_interrupt_handler(void)
{
printf("GPIO5 has been interrupted\n");
gpio_irq_served = TRUE;
}
int gpio_irq_test(void)
{
printf("Start GPIO5 IRQ test:\n");
gpio5_iomux_config();
gpio_set_direction(GPIO_PORT5, GPIO5_PIN10, GPIO_GDIR_INPUT);
*(GPIO5_ICR1) = (uint32_t)0xc00; // GPIO5 ICR1 falling edge for IO5
*(GPIO5_IMR) = (uint32_t)0x20; // GPIO5 IMR enabling mask for IO5
/* register the IRQ sub-routine */
register_interrupt_routine(IMX_INT_GPIO5_INT15_0, gpio_interrupt_handler);
/* enable the IRQ */
enable_interrupt(IMX_INT_GPIO5_INT15_0, CPU_0, 0);
while (gpio_irq_served == FALSE);
return TEST_PASSED;
}

2, Calling of the function defined above hase been added into all_test.c whitch placed into ../apps/sdk_unit_test/src/
3, Also I have just added the test printf into the source file of interrupt.c, whitch stored at ../sdk/core/src
//! @brief Handles IRQ exceptions. __attribute__ ((interrupt("IRQ"))) void IRQ_HDLR(void) { // vectNum = RESERVED[31:13] | CPUID[12:10] | INTERRUPT_ID[9:0] // send ack and get ID source uint32_t vectNum = gic_read_irq_ack(); printf("[IRQ_HDLR]start, vectNum = 0x%x\n", vectNum);
4, When compiled finished, I just run the test and got the result like below:
Just like described above, I found that in the Platform_SDK, the interrupt function named IRQ_HDLR[intterrupt.c] could not be executed at all
Could anyone please tell me how to enable interrupt execution about Platform SDK?
