A simple way to work around this is to only use RTT logging in either the bootloader or application at the same time, but for a proper solution the best is probably to ensure they use the same memory block for RTT. A customer described how you can do that in <a href="https://devzone.nordicsemi.com/f/nordic-q-a/30310/easy-way-to-merge-bootloader-and-application-rtt-output">this thread</a>&nbsp;(exact method depends on which toolchain you are using, but the principles remain the same).</p><div style="clear:both;"></div>
