https://devzone.nordicsemi.com/f/nordic-q-a/74118/uart-logging-on-nrf52832Hi everyone, I&#39;m currently trying to the get UART logging running on the NRF52832, but fail to get the SDK working. My settings are as follows: #define NRFX_UARTE_ENABLED 1 #define NRFX_UARTE0_ENABLED 0 #define NRFX_UART_ENABLED 1 #define NRFX_UART0_ENABLEDen-USTelligent Community 13Sat, 24 Apr 2021 17:14:17 GMThttps://devzone.nordicsemi.com/thread/306635?ContentTypeID=1Sat, 24 Apr 2021 17:14:17 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ea4e62c2-bb5f-42e1-8335-6dd5dc50a94cwait-for-it<p>Thanks, that fixed the problem!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/305523?ContentTypeID=1Mon, 19 Apr 2021 12:17:12 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d51a8eab-5071-4e59-81bb-43a2ffd1300cSimonr<p>Hi</p> <p>A few things you can try that has fixed this &quot;multiple definition error&quot; of the &quot;UARTE0_UART0_IRQHandler&quot;:</p> <ul> <li>Try disabling legacy UART peripheral support by setting #define UART_LEGACY_SUPPORT 0 in your sdk_config.h file.</li> <li>Enable peripheral resource sharing for UART/UARTE. This is done by setting #define NRFX_PRS_ENABLED 1 and #define NRFX_PRS_BOX_2_ENABLED 1 in sdk_config.h.</li> </ul> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
