''TBD: sostituire con le informazioni del connettore e del pinout'' JTAG signals are routed to a dedicated connector on the primary ETRA PCB.  The connector is placed on the top side of the PCBJ1, at the upper-right corner (please see the picture below). [[File:ETRA-jtag-conn.pngSOM/ETRA Hardware/Pinout Table|500px|frameless|borderConnectors and Pinout Table]] == ''TBD:CONN-REF'' - Connector's pinout == ''TBD:CONN-REF'' footprint mates with ''TBD:CONN-TYPE'' connector.
