Recently I started to evaluate a development kit that cost about $US 180. Taking the kit beyond a basic demonstration, though, required using a “JTAG” programming ...

Several processor vendors have extended JTAG software debug, often to make it faster, or to add hardware trace capabilities. The NEXUS consortium for example defines an auxiliary port containing a ...

On chip debug firm Macraigor Systems has introduced a full-speed mini Universal Serial Bus (USB) device for JTAG (IEEE Standard 1149.1) or BDM (background debug mode). Called usbSprite, the tool ...

JTAG debuggers tend to be large, fast, and expensive, or cheap and slow. The new crop of USB-based JTAG debuggers is cutting the cost while keeping the performance high. I recently had a chance to ...

Xilinx Vertex-II Pro platforms that support multiple PowerPC and MicroBlaze cores have a new weapon in the EMUL-PPC JTAG debugger. The package, including software support, handles hardware diagnostics ...

A new embedded debugger is the first in system JTAG based debugger for Intel x86 platforms. According to Asset InterTech, the debugger implements hardware based run control in system firmware. Once it ...

[Joe Grand] has come up with a tool which we think will be useful to anyone trying to hack a physical device: The JTAGulator. We touched on the JTAGulator briefly during our DEF CON coverage, but it ...

XJTAG has introduced a JTAG chain debugger which is designed to enable engineers using its boundary scan system to improve printed circuit board (PCB) set-up times and to troubleshoot faults on early ...

Electronic enthusiasts and Raspberry Pi users may be interested in a new JTAG debugger board called Tap-Hat which has been created by the team at eCosCentric. The TAP-HAT has been designed to provide ...

As with many Linux-related topics, the issue of using debuggers to troubleshoot the Linux kernel is not only technical--it's political. Linux is being mostly developed on the x86 platform, which does ...
