https://devzone.nordicsemi.com/f/nordic-q-a/39117/legacy-uart-required-for-uart-backendIn `nrf_log_backend_uart.c` there is a reference to `./integration/nrfx/legacy/nrf_drv_uart.h`. I&#39;m upgrading the system to use the Nordic provided backend, but it would be great if I can use something that will be supported for a while.

This is useful for backwards compatibility. But it&rsquo;s the new nrfx drivers that are actually being used. See <a href="https://devzone.nordicsemi.com/f/nordic-q-a/32919/nrfx-sdk-15-upgrade-suggestions">this post</a>. I suggest keeping it as it is.</p><div style="clear:both;"></div>
