Adding this to the .overlay file for you board should make the printk statements output the text on UART1:

/ {
    chosen {
        zephyr,console = &uart1;
    };
};

Hi Jorgen,

1. Just one print statement

2. printk("Hello Nordic family from uart1")

Like I said, the code is already printing on UART1. If you want me to show you how to print something else on UART1, you need to tell me what you want to be printed.

Hi Jorgen,

Thank you for your time and effort

1. If Possible could you modify the code to print from uart1

2. Then i can understand code clearly

Hi,

I'm not sure if I understand what you want. Do you want the printk() statements in the code output on UART1?

The code already works by outputting text on both UART0 and UART1. The strings input on UART0 will be output on UART1, and text input on UART1 will be output on UART0. If you want to output other data to UART1, you can use the function print_uart(uart_dev1, rx_buf1); as I have done in the code, to print the context of rx_buf1 on UART1.

The printk statements in code depends on the devicetree configs in the project.

Best regards,
Jørgen
