I have designed a custom board based on nRF5340. Now I am trying to do flashing and RF testing of it through nRF5340 development board but it flash but can't run RF tesing . After successful flashing of custom board , doing the Direct Test Mode  but it shows the error.

so is there any alternate option or any solution regarding it.

Visual Studio Code version: 2.9.1
nRF connect for desktop version: 5.2.0
DTM version: 2.5.0

Nothing seems obviously wrong in your project build view

Can you please explain a bit in details what do you mean when you write "it shows the error"? If you run the sample sample built for the DK instead of your custom board, does everything work ok?

i am using the sample of DTM in VS code . I only do the change in my overlay file where i configure the UART TX ,RX . Rest of the data are same . but when i start test in NRF connect for desktop DTM then there will be showing the error that i attached below. 

&pinctrl {
    uart0_default: uart0_default {
        group1 {
            psels = <NRF_PSEL(UART_TX, 0, 8)>;
        };
        group2 {
            psels = <NRF_PSEL(UART_RX, 0, 9)>;
            bias-pull-up;
        };
    };

    uart0_sleep: uart0_sleep {
        group1 {
            psels = <NRF_PSEL(UART_TX, 0, 8)>,
                    <NRF_PSEL(UART_RX, 0, 9)>;
            low-power-enable;
        };
