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 ...

Bill found that Macraigor Systems’ usbSprite is slightly larger than a postage stamp but provides full-featured JTAG debugging. Good things still come in small packages. JTAG debuggers tend to be ...

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.

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 ...

Part two explains the workings of the JTAG boundary-scan technology. Part four explains how to use breakpoints, event triggers, and program traces to debug code. Emulation is a technology used in the ...

Tap-Hat is a multi-purpose JTAG debugger board for those developing software to run on Raspberry Pi: RTOSs, Linux and bare-metal code in particular. Photo of prototype As well as this, the board can ...

With each turn of Moore's Law, designers at every phase in the development process are challenged with new levels of complexity. Chip designers must not only get the integrated circuit (IC) logic, ...

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 ...

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 ...
