hi Priyanka,

Yes, I have tried. but I didn't get results for that specific pins. So I started the below ticket

Thanks & Regards

Hi Navin,

Have you tried the peripheral_uart sample? Do you get the results?

Hi priyanka,

I have configured pin 32 and 33 as rx and tx and I have tested the ble peripheral sample . I didn't get the proper result through uart.

Shall i need to configure anything??

Thanks & regards

The J-link debuggers are specifically for debugging and the DKs have an onboard debugger which you can use for the debugging purpose similar to any stand-alone debuggers. If you wish to connect the DK, you can use the Debug ports on the DK. Unfortunately we cannot recommend any names for external products and you will have to decide this upon your requirements.

Hi Priyanka,

I understood your point. I want to know the below things also.

1) In the production stage. for debugging purposes which is the best tool nrf5340dk or any jlink debugger.

2) If the debugger is the best tool to use for production means. Kindly, share with me the correct product link to purchase.

3) and also let me know what is difference between both the tool specifically for debug purpose

Hi Navin,

Maybe you could refer this ticket for RTT logging for Zephyr.

Hi Priyanka,

[quote userid="107729" url="~/f/nordic-q-a/89101/debug-uart/373480"]You could try with the hello_world sample and check if hello_world gets printed.[/quote]

I have tried this, but this is not working.

I think UART sample or debug using RTT is the only way. but already I am going to use I2c1, i2c2, SPI, and PDM. So, according to the dts I can't able to enable uart in my case right??

Hi Navin,

You could try with the hello_world sample and check if hello_world gets printed. You can also take a look at the peripheral_uart sample, but here, for logging, Segger RTT is used. Since you are using a custom board, you will need to make an overlay file in order to set the proper UART pins for the board.

In your sdk config, edit NRF_LOG_BACKEND_UART_TX_PIN To your TX pin.
