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?
Hi Tong
please look at attached code it may help
you (based on SDK).
Best regards

Hi chipexpert
Thanks for your kindly help.
I will learn the attach and check with my test now.
