My nRF 52833 DK cannot print information to the serial porthttps://devzone.nordicsemi.com/f/nordic-q-a/110741/my-nrf-52833-dk-cannot-print-information-to-the-serial-portHello, I have several nRF52833 DKs (from different manufacturers). However, one of the DKs is unable to print information to the terminal of putty, and I&#39;m unsure why. The nRF Connect SDK environment is fine. The same code flashed onto other DKsen-USTelligent Community 13Mon, 06 May 2024 07:18:58 GMTRE: My nRF 52833 DK cannot print information to the serial porthttps://devzone.nordicsemi.com/thread/481920?ContentTypeID=1Mon, 06 May 2024 07:18:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d5ad91b1-1281-422a-909f-079bf7ce2356Zihao<p>Thank you very much!

I tried modifying the contents related to UART_TX and UART_RX in the nrf52833dongle_nrf52833.dts file, but it did not help.[/quote] <p>If you are normally building for the DK&#39;s, then I would expect this is the file you should look at:<br />\zephyr\boards\arm\nrf52833dk_nrf52833\nrf52833dk_nrf52833-pinctrl.dtsi&nbsp;</p> <p>In any case, it may be a good idea to connect a logic analyzer to the pins in question to check if there is any data, baudrate etc.</p> <p>Kenneth</p><div style="clear:both;"></div>
