Linux-ready trace port analyzer supports Intel CPUs

Apr 13, 2010 — by Eric Brown — from the LinuxDevices Archive — 4 views

Arium announced a new JTAG debugger In-Target Probe (ITP) trace port analyzer device for debugging Linux-based devices. The LX-1000 stores events in on-board high-speed RAM, and initially targets Intel processor platforms.

Arium announced the new probe at the Intel Developer Forum in Beijing, highlighting the device's Intel platform support. The LX-1000 is currently available for Intel Atom, Pentium, Celeron, Core, and Xeon processors, and will soon support other architectures, says the company. (Arium has traditionally supported ARM platforms, and more recently expanded onto Intel-based devices.)

The LX-1000 is the fastest trace port analyzer on the market, claims Arium. The device is designed to complement the company's ECM-XDP3 JTAG debugger (pictured below, at right), which offers code execution trace on Intel platforms using last branch registers (LBR), cache-as-RAM (CAR), and DRAM. The LX-1000 adds a fourth tracing resource by storing events in onboard high-speed RAM, says Arium.

The LX-1000 device captures events from the eXtended Debug Port (XDP), and supports trace depths of 2GB, with optional 4GB and 8GB storage, says the company. An LX-INT option offers a control module for Intel processors, and the company will soon offer LX-PAR and LX-SER options, which are said to support ARM devices with parallel ETM and serial trace (using both Marvell SETM3 and ARM HSSTP), respectively. 

The LX-1000's trace capture engine traces instructions and data at rates of up to 680MHz, and is sufficiently wide to support up to six lanes of serial trace packets at up to 6.25GHz, says Arium. Interfaces include USB 2.0 and gigabit Ethernet ports, and trigger I/O is also available, says the company. The device appears to replace older Arium trace port analyzers such as the circa-2005 GT-1000D (pictured above left).

The LX-1000 is designed to be used with Arium's SourcePoint debugging software, which was released last September in a Linux-ready version 7.7.1. The new version adds Intel Atom support, code trace features, and flash programming functionality. The software is said to run on both Linux and Microsoft Windows hosts.

Stated Larry Traylor, Arium CEO, "As Intel-based designs and software become more complex, developers need more visibility to events occurring on target platforms. The LX-1000 provides another window into what occurred on the target to help track down bugs."


The LX-1000 will start shipping later this month for Intel platforms, says Arium. Pricing was not listed. More details can be found here.
