nRF5340 cpunet configuration problem

[.....]

Hello,

I have problem with configuration.

My project is based on the project: GitHub - nordic-auko/nRF5-ble-timesync-demo: nRF52 clock synchronization demo code.
Timesync project is intended to be built on cpunet, so also my project.

I want to add additional buttons, leds, leds controlled by pwm, pin for controlling pullup, and one wire. I have problem with pwm leds. 

I made custom board based on nRF5340DK board (and I placed it in SDK folder)

in board_nrf5340_cpunet.dts I added (compared to nRF5340DK):
aliases {

        watchdog0 = &wdt0;

        onewpu = &onewpullup;

        onewire = &onewire;

        fpwren = &fpwren;

    };

in board_nrf5340_cpuapp.dts I added:

/ {

   [ ... ]

    m_pin {

        compatible = "gpio-leds";

        onewpullup: one_w_pull_up {

            gpios = <&gpio1 15 GPIO_ACTIVE_HIGH>;

            label = "one_w_pull_up";

        };

        onewire: one_wire {

            gpios = <&gpio1 5 (GPIO_PULL_UP)>;

            label = "ONE_WIRE";

        };

        fpwren: fpwr_en {

            gpios = <&gpio0 8 GPIO_PULL_UP>;

            label = "fPWR_EN";

        };

    };

   

    leds {

        compatible = "gpio-leds";

        ledr: led_r {

            gpios = <&gpio1 6 GPIO_ACTIVE_LOW>;

            label = "LED_R";

        };

        ledb: led_b {

            gpios = <&gpio0 26 GPIO_ACTIVE_LOW>;

            label = "LED_B";

        };

        ledl: led_l {

            gpios = <&gpio0 24 GPIO_ACTIVE_LOW>;

            label = "LED_L";

        };

    };

    pwmleds {

        compatible = "pwm-leds";

        pwm_led0: pwm_led_0 {

            pwms = <&pwm0 0 PWM_MSEC(20) PWM_POLARITY_INVERTED>;

        };

        pwm_ledcr: pwm_led_c_r {

            pwms = <&pwm0 1 PWM_MSEC(20) PWM_POLARITY_INVERTED>;

        };

        pwm_ledcg: pwm_led_c_g {

            pwms = <&pwm0 2 PWM_MSEC(20) PWM_POLARITY_INVERTED>;

        };

        pwm_ledcb: pwm_led_c_b {

            pwms = <&pwm0 3 PWM_MSEC(20) PWM_POLARITY_INVERTED>;

        };

    };

    buttons {

        compatible = "gpio-keys";

        buttonbtn: button_btn {

            gpios = <&gpio0 12 (GPIO_PULL_UP | GPIO_ACTIVE_LOW)>;

            label = "Button BTN";

            zephyr,code = <INPUT_KEY_0>;

        };

    };

};

&pwm0_default {

    group1 {

        psels = <NRF_PSEL(PWM_OUT1, 1, 3)>,

                <NRF_PSEL(PWM_OUT2, 0, 22)>,

                <NRF_PSEL(PWM_OUT3, 0, 4)>;

                <NRF_PSEL(UART_RX, 0, 17)>;

    };

};

&qspi_default {

    group1 {

        psels = <NRF_PSEL(QSPI_IO0, 0, 13)>,

                <NRF_PSEL(QSPI_IO3, 0, 16)>;

        onewire = &onewire;

        fpwren = &fpwren;

When I commented lines in board_5340_cpunet.overlay file and I left these lines of code:

What needs to be changed so that the application builds correctly?

* I am building application in VS Code with SDK v3.1.1 for cpunet

Hi!

The PWM is on the app-core only, net-core does not have control over the PWM peripheral( hardware limitation). So you need to control the PWM from the app-core.

[.....]

Can you describe how to control PWM from app core when my application is building for net core ?

Does it require only configuration changes or also changes in the application code?

[Sigurd]

Hi!
You would need a application for the app-core as well. configuration changes only are not enough, you need some application code as well.
