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 ...

XJTAG has introduced its second generation boundary scan test system which supports multiple JTAG chains and provides measurement of supply rail voltages and signal frequencies. “The XJTAG XTR series ...

A few weeks ago we wrote about our Bus Pirate universal serial interface tool. We used the recent holiday to add some new features, like a JTAG programmer, macros, frequency measurement, and more. A ...

– Extend the IEEE 1149.1 Test Bus into a Multi-drop Backplane Environment (This allows cards to be removed from the backplane without breaking the JTAG chain) – A Mode Register Allows Local TAPS to be ...

Wouldn’t it be great if there were just one standard for attaching to, programming, and debugging hardware? If you could just plug in and everything would just work? Dream on, dreamer! But of course ...

Download the PDF of this article. These days, hardware debug interfaces like the Joint Test Action Group (JTAG) IEEE 1149.1 standard are ubiquitous. You can find them on many microcontroller and ...

XJTAG, a supplier of boundary scan development tools, has added a JTAG chain debugger to its XJTAG Development System. XJTAG claims JTAG will reduce debug and test times for engineers designing and ...

A daisy chain consisting of multiple devices can be quite cumbersome to control, especially when the only device that needs updating is the last one in the chain. Each device in the chain must be ...

It is fairly common knowledge that hacking into today’s intelligent Internet devices is child’s play in most cases. The main reason is that the devices have little or no innate security designed in.
