lsio interrupt configuration

Lakshmi_AG — Wed, 17 May 2023 03:53:43 GMT

Hi,

I am trying to enable an interrupt for the GPIO on imx8qm.

SCU configuration:

config.pinDirection = kRGPIO_DigitalInput;
        pad_force_mux(SC_P_SCU_GPIO0_00, 3, SC_PAD_CONFIG_NORMAL,
            SC_PAD_ISO_OFF);
        pm_force_resource_power_mode(SC_R_GPIO_0, SC_PM_PW_MODE_ON);
        FGPIO_PinInit(FGPIOA, 0U, &config);

Tried to validate the GPIO by reading form GPIO offset memory

read_gpio0 = *(uInt32 *)0x5D080000;

Till here it is working but now i am trying to enable the interrupt for same

#define LSIO_GPIO0_ADDR (0x5D080000)

LSIO1 = (LSIO_GPIO_Type*)mapPhysicalAddress64(LSIO_GPIO0_ADDR, 1, userAccessNone, cachingOff);

LSIO1->ICR2 = (3 << 24);
LSIO1->IMR |= (1 << 28);

But above ICR and IMR are not working.

Need help to check where am i going wrong.

Hi Lakshmi

This code seems not from MQX 4.2.

I would suggest you contact local FAE for support
