NRF Printk

[LinJunXuan]

I want to use the UART20 serial port to map to other pins for easier PCB layout, but when I use the NRF54L15，

overlay config

debug_uart20_default: debug_uart20_default {
        group1 {
            psels = <NRF_PSEL(UART_TX, 1, 5)>;
        };
    };
	debug_uart20_sleep: debug_uart20_sleep {
        group1 {
            psels = <NRF_PSEL(UART_TX, 1, 5)>;
			low-power-enable;
        };
    };
    
    
    
    
mouse_debug:&uart20 {
    status = "okay";
    current-speed = <9600>;
    pinctrl-0 = <&debug_uart20_default>;
    pinctrl-1 = <&debug_uart20_sleep>;
    pinctrl-names = "default","sleep";
};

my main code 

 bsp_board_init();
    
    while (1) 
    {
        drv_sensor_init();
        dsadsa = bsp_adc_get_value(ADC_CHANNEL_0);
        printk("volatage : %d mv\n", dsadsa);
        k_msleep(1000);
    }

but  no printk  or printf

What should I do ? 
Or, in other words, only the default P1.04 can be used

Hi,

Do you mean to say that the P1.05 that you are using the code doesn't seem to get the output, but only when you use P1.04, it works?

Regards,

There is another issue, which is that when I am using the Bluetooth routine (which is a routine for Bluetooth practice one), the board selected 'compact' without any error, but when I selected 'Nordic Soc', it reported an error, and the error that kept happening was' Clock '. I have been following Nordic's AI to solve this problem, but it has not been resolved

Hello, I have encountered a very strange problem now. My initialization has blocked all my code, only Printk but no printing. Is it possible that there is a problem with my project?? This is my overlay

I found the problem, it's really strange. I just wanted to engineer code that can use 2.4G and BLE, but surprisingly

I just need to annotate here, why is this happening????

Hi,

i am a bit confused with what your issue is.

Could you tell me a bit more clearly as to what your current problem is?

Is it that you are not observing any output even though you are using printk statements?

-Priyanka

[LinJunXuan]

Yes, my main function has nothing, only printk still hasn't output, but commenting out the above 2.4g prj.conf is enough. I think this problem can be reproduced. I don't understand why this happened

[Priyanka]

Hi,

Sorry for the late response.

But I think maybe the issue was with your overlay configuration.

The initial ay you tried was correct, but could you add the following to your overlay file?

/ {
chosen {
zephyr,console = &uart20;
zephyr,uart-mcumgr = &uart20; /* optional */
};
};

In your overlay file, you are just defining the pinctrl, etc, but I think maybe without the chosen { zephyr,console = &uart20; } line, printk() may go to another backend (often RTT), which then looks like “no output.”
