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.

Which probe?

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
This debug and trace unit enable powerful debug and optimization of any Arm processor-based hardware target. Ideal for comprehensive debug of Arm architectures v4 to v8 up to 9.6 Gbps (parallel trace) when used alongside Arm Development Studio.
