Auxiliary (AUX) connector
The Auxiliary (AUX) connector on the front of DSTREAM-ST is reserved for future use and is intended to support external probes for high-speed trace capture (for example, 32-bit, HSSTP, or PCIe).
This connector is not intended for user I/O. Do not attempt to connect anything other than Arm® DSTREAM-ST probes.
This connector is not compatible with older RealView Trace (RVT) probes.
