DSTREAM-ST Debug Adapter
DTREAM-ST debug and trace probes debug and optimize software running on any Arm-based hardware target. It streams the data live to the host PC over USB or GbE interfaces to accelerate the debug process.
When used alongside Arm Development Studio, the DSTREAM-ST is a key tool to accelerate code development especially when developing complex SoCs. And if required it can be used alongside third party tools via the open debug interface.
DSTREAM-ST superseded our first-generation DSTREAM Debug Adapter. In case you are looking for tracing capabilities, learn more about DSTREAM-PT.
Purchase
DSTREAM debug units can be purchased directly from our global distribution partner, Digi-Key
