It will not change where the printf uart serial data is printed. The debug terminal only supports RTT which use the SWD protocol, uart is not supported.&nbsp;</p> <p>regards<br />Jared</p> <div></div><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/388738?ContentTypeID=1Fri, 30 Sep 2022 10:51:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:679636bf-a868-4aa8-a77f-538e949eb6ddkunchalaRajesh<p>Can you guide how to change that RTT backend.because in my SDK_config.h file i gone through CMSIS configure wizard.their also RTT logger&nbsp; not showing.even i installed J link RTT software also.still RTT setting not showing anywhere in sdk_config.h file</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/388694?ContentTypeID=1Fri, 30 Sep 2022 08:44:53 GMT137ad170-7792-4731-bb38-c0d22fbe4515:cd205d86-5945-45e1-ab82-69591439463bJared<p>Hi there,</p> <p>The debug terminal in SES only outputs logs that use the RTT backend, not UART backend. If you want logs to be printed to the debug terminal in SES then you would have to change the logger backend to RTT instead of UART in the project sdk_config.h file.&nbsp;</p> <p>regards</p> <p>Jared&nbsp;</p><div style="clear:both;"></div>
