FRDM-MCXN947 GPIO_PortClear() not working and why?

[saulius1005]

Hi, My problem is simple- Recently I just start play with FRDM-MCXN947 board. According to tutorial I create C project file. My first test should be Green color  simple on and off (onboard RGB led) . Program written by me looks like that:

    while(1) {
        i++ ;
        if(i==1){
        	GPIO_PortSet(BOARD_INITDEBUG_UARTPINS_LED_GREEN_PORT, BOARD_INITDEBUG_UARTPINS_LED_GREEN_PIN_MASK);
        }
        if(i==20000000){
        	GPIO_PortClear(BOARD_INITDEBUG_UARTPINS_LED_GREEN_PORT, BOARD_INITDEBUG_UARTPINS_LED_GREEN_PIN_MASK);
        }
        if(i==40000000){
        	i=0;
        }
        /* 'Dummy' NOP to allow source level single stepping of
            tight while() loop */
        __asm volatile ("nop");
    }

I just did some changes (main source file) inside while loop and other part is not changed at all.

I try run debugging and GREEN led turn on but never turn off. Of course I did changes in required pin changes with integrated config tool. Also here printscreens from main source file, pinmux and config screens:config screen

port_mux.h

main.c

Those files already included trought board.h (at least I think so):

And bdw  all project files is automatically generated. And my opinion all necessary files and includes should be inside.

gpio driver version 2.7.3:

GPIO_PortClear at fsl_gpio.h

[JoeSanchez]

I don't see fsl_gpio.h is added as part of #includes, try adding that and make sure that fsl_gpio.c and .h is part of your project so it will be compiled

[JoeSanchez]

Are you using SDK 2.5? If i remember correctly, fsl_gpio.h PortClear and PortSet has 3 arguments. verify your version of gpio driver you are using

Problem solved instead of this

BOARD_INITDEBUG_UARTPINS_LED_GREEN_PORT

use this:

BOARD_INITDEBUG_UARTPINS_LED_GREEN_GPIO

or this:

BOARD_INITLEDSPINS_LED_GREEN_GPIO

but why same defined twice with different names...?

Code after all changes: 

    while(1) {
        i++ ;
        if(i==1){
        	GPIO_PortSet(BOARD_INITLEDSPINS_LED_GREEN_GPIO, BOARD_INITLEDSPINS_LED_GREEN_PIN_MASK);
        }
        else if(i==2000000){
        	GPIO_PortClear(BOARD_INITLEDSPINS_LED_GREEN_GPIO, BOARD_INITLEDSPINS_LED_GREEN_PIN_MASK);
        }
        else if(i==4000000){
        	i=0;
        }
        /* 'Dummy' NOP to allow source level single stepping of
            tight while() loop */
        __asm volatile ("nop");
    }
