Imx8qxp M4 GPIO_PinInit failed

[relax-wu]

Hi

    SCFW has allocated the group of gpio IMX8QXP_QSPI0A to M4.
    Failed to initialize GPIO in M4
    Modify as follows:

I solved it myself。

https://community.nxp.com/t5/i-MX-Processors/imx8qxp-M4-How-to-use-flexspi-pins-as-normal-GPIO/td-p/...

MCU-SDK：android_build/vendor/nxp/mcu-sdk-auto/SDK_MEK-MIMX8QX/boards/mekmimx8qx/demo_apps/rear_view_camera

When this function is executed, an error occurs and the program dies

//vendor/nxp/mcu-sdk-auto/SDK_MEK-MIMX8QX/devices/MIMX8QX6/drivers/fsl_gpio.c
void GPIO_PinInit(GPIO_Type *base, uint32_t pin, const gpio_pin_config_t *Config)
{
    ......

	/* Enable GPIO clock. */
    CLOCK_EnableClock(s_gpioClock[GPIO_GetInstance(base)]);

    ......
}

Hi relax

the same IMX8QXP_QSPI0A signals may be used in other ..driver_examples/flexspi sdk example, so

one can try to comment them there.

Best regards

Hi igor

    The configuration steps are simple.
    Now that there is a problem, there are two possibilities:
        1. My configuration is wrong
        2. There is a problem with your SDK(Q10.0.0_2.2.0_AUTO)

    Please feedback to the technical staff to confirm it.

thank you very much
