=== GPIO in J990 ===
Reset [[Mux instructions#WIFI|WIFI]], [[Mux instructions#Bluetooth|BT]] or [[Mux instructions#TP65950_PCM_VSP|TPS]] if you use some pad shared with this connector, more information [[Connectors Summary#J990_connector|here]].
Configure GPIO, don't use [[Frequently Asked Questions and Their Answers#Is_it_possible_to_config_the_wireless_LAN_and_bluetooth_so_they_are_completely_off.2C_and_not_consuming_any_power_at_all.3F|these GPIO]] in IGEP WIFI/BT versions.<br>
Use [[How to use GPIOs|this manual]] to configure mux via user space<br>
