Processor Debug Header P-XDP
The SC3-LARGO may be equipped with a 26-position processor debug header for hard- and software
debugging (specified by Intel
®
as XDP-SFF-26 Pin Platform Connection). The connector is suitable for
installation of a flat flex cable (FFC), in order to attach an JTAG debugger (emulator) such as the
Arium ECM-XDP3. An adapter (ITP-XDP-SFF-26) is required in addition to convert the 26-pin
XDP-SFF-26 Pin connector to the standard 60-pin XDP.
The header P-XDP would be mounted on the PCB bottom side, but is not stuffed by default.
