JTAG (jay-tag) is one of the engineering acronyms that has been transformed into a noun, although arguably it is not so popular as RAM, or CPU. IEEE Std 1149.1-1990 IEEE Standard Test Access Port and ...

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 ...

Microchip Technology has introduced the MPLAB PICkit Basic, an affordable and versatile in-circuit debugger designed to simplify programming and debugging for engineers, hobbyists, and students. The ...

We don’t always JTAG, but when we do, we use a Black Magic Probe. It’s a completely open ARM-chip debugging powerhouse. If you program the small ARM chips and you don’t have a BMP, you need a BMP.

[Surya Chilukuri] writes in to share JTAGprobe — a fork of the official Raspberry Pi debugprobe firmware that lets you use the low-cost microcontroller development board for JTAG and SWD debugging ...

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 ...

The JTAG port was introduced more than 30 years ago, but has changed as the industry has evolved, says James Stanbridge. For some engineers the term JTAG means a device programming port. For others it ...
