DSTREAM Debug Adapter

DSTREAM debug and trace probe enables software debug and optimization of any Arm-based hardware target.

When used alongside Arm Development Studio, it accelerates debug and hardware bring-up, including for complex SoCs. And if required, it can be used in conjunction with third-party tools via its open debug interface.

Which probe?

DSTREAM
This debug and trace unit enables 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.

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.

Features & Specifications

Debug protocol
JTAG and serial-wire debug.

Target connectors
Target connectors for the DSTREAM probe include 14-pin and 20-pin Arm JTAG, 14-pin TI OMAP, 10-pin and 20-pin high density CoreSight connectors, 38-pin MICTOR, 34 pin MIPI and 60 pin MIPI (QSH-60) via optional adapter.
