@linguini1 I am not sure what i am doing wrong. It is also not working on
master for me.
I tried expanding my code, but this also does not work.
I followed some button examples, which dont work for me.
My debugger shows the interrupts are never triggered.
I am however not using the GPIO driver. I want a "bare metal" approach, but
I'm guessing something goes wrong there?
Perhaps this looks similar to the Pico SDK, but behaves completely
differently.
```C
int custom_irq(int irq, FAR void *context, FAR void *arg)
{
syslog(LOG_DEBUG, "HELLO!");
rp2040_gpio_put(BOARD_GPIO_LED_PIN, false);
return 0;
}
void rp2040_boardearlyinitialize(void)
{
#ifdef CONFIG_ARCH_BOARD_COMMON
rp2040_common_earlyinitialize();
#endif
/* --- Place any board specific early initialization here --- */
/* Set board LED pin */
rp2040_gpio_init(BOARD_GPIO_LED_PIN);
rp2040_gpio_setdir(BOARD_GPIO_LED_PIN, true);
rp2040_gpio_put(BOARD_GPIO_LED_PIN, true);
/* Test interrupt */
volatile int ret;
rp2040_gpio_disable_irq(3);
rp2040_gpio_init(3);
rp2040_gpio_setdir(3, false);
rp2040_gpio_set_pulls(3, 1, 0);
ret = rp2040_gpio_irq_attach(3,
RP2040_GPIO_INTR_EDGE_LOW,
custom_irq,
NULL);
rp2040_gpio_enable_irq(3);
}
```
result:
ret = 0
function does not get triggered (also not the breakpoint).
Are all the interrupts being reset after board initialization somewhere?
I need help to figure this out
