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?

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.

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.

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.
