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DSTREAM-ST superseded our first-generation DSTREAM Debug Adapter.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.

DSTREAM-ST
If your projects need fast downloads, high JTAG clock rates and limited parallel streaming trace, then the DSTREAM-ST is the debug probe of choice. Used alongside Arm Development Studio you can develop your software faster.
DSTREAM-PT
This high-performance debug and parallel trace unit enables powerful debug and optimization of any Arm processor-based hardware target. Ideal for any Arm architectures, supporting a maximum of 19.2 Gbps parallel trace when used alongside Arm Development Studio.
DSTREAM-HT
This high-performance debug and parallel trace unit enable powerful debug and optimization of any Arm processor-based hardware target. Ideal for any Arm architectures, supporting a maximum of 19.2 Gbps parallel trace when used alongside Arm Development Studio.
Debug protocol
JTAG and serial-wire debug.
Target connectors
Target connectors for the DSTREAM-ST probe include 14-pin ad 20-pin Arm JTAG, 14-pin TI OMAP, 10-pin and 20-pin high density CoreSight connectors and 38-pin MICTOR.
Speed
4-bit wide trace capture at 300 MHz DDR (600 Mbit/s per pin).
Software requirements
This debug probe is best used alongside Arm Development Studio (which is sold seperately). If required, it can be used alongside third party tools.
