https://devzone.nordicsemi.com/f/nordic-q-a/128817/can-traces-be-pulled-through-unused-ballsI have a similar question to this , however it&#39;s for the nRF54 family. Can I route similar the SWD signals out through unused pins/balls on a BGA? In this case, I&#39;d route SWDIO through G2 and SWCLK through F4 and G5.

All GPIOs are disconnected by default and won&#39;t interfere with the SWD pins.</p><div style="clear:both;"></div>
