Logs Not apperaring while running radio_test sample on custom nrf board

Hello i am running the radio_test sample on the custom nrf5340 board for the logging purpose i am using the pins 8 and 9 of the port 0 but the issue arising is that there are no logs appearing after flashing the board 

The overlay file i have modifeid for the remote_shell looks like this

/ {
    chosen {
        zephyr,shell-ipc = &ipc0;
        ncs,remote-shell-uart = &cdc_acm0;
    };
};

&zephyr_udc0 {
    cdc_acm0: cdc_acm0 {
        compatible = "zephyr,cdc-acm-uart";
    };
};
 

&pinctrl {

    uart0_default: uart0_default {

        group1 {

            psels = <NRF_PSEL(UART_TX, 0, 8)>, <NRF_PSEL(UART_RX, 0, 9)>;

        };

    };

 

    uart0_sleep: uart0_sleep {

        group1 {

            psels = <NRF_PSEL(UART_TX, 0, 8)>, <NRF_PSEL(UART_RX, 0, 9)>;

        };

    };

};

&uart0 {

    status = "okay";

    current-speed = <115200>;

    pinctrl-0 = <&uart0_default>;

    pinctrl-1 = <&uart0_sleep>;

    pinctrl-names = "default", "sleep";

};

other things i am not changing my custom board has not usb support for the build configration i am selecting nrf5340dk/nrf5340/cpunet as board target and pragma file of the prj.conf i will be very thankful for any help given
