PCle
Host connector
Connects to the DSTREAM-ST unit using a 60-way ribbon cable. The Host connector also
controls the XT probe and retrieves trace data from it.
Debug via PCIe connector
Passes debug signals from DSTREAM-ST unit to the PCIe connector. It connects to the
DSTREAM-ST unit using the Arm JTAG 20 cable.
This connector is only required when using the low-level, single-ended JTAG
connections of the PCIe interface. When performing debug using the main
PCIe interface or a separate debug connector on the target, this connector is
not required.
If the target uses separate debug and trace connectors, the debug connection must be made
directly between the DSTREAM-ST unit and the target, leaving this connector, on the XT
probe, unused.
PCIe connector
Connects the XT probe to the appropriate DSTREAM-XT adapter using the provided 98-way
ribbon cable.
