If you’re reading Hackaday, you’ve almost certainly heard of JTAG. There’s an excellent chance you’ve even used it once or twice to reflash an unruly piece of hardware. But how well do you actually ...

Figuring out the JTAG pinout on a device turns out to be the most time consuming hardware portion of many hacks. [hunz] started a project called JTAG Finder to automatically detect the JTAG pinouts on ...

Most complex electronic systems take advantage of the IEEE 1149.1 (JTAG) standard in one way or another. If the system uses complex FPGAs or CPLDs, then they are almost certainly configured using the ...

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.

When developing a new board, many problems can occur. Bare, unpopulated boards can have shorts and opens that can cause circuits not to work or software to fail once the board is populated. After ...

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 ...

Boundary Scan technique is most often thought of as a board-level test method, but certain techniques makes system level test with JTAG quite effective. Many types of faults can arise when systems are ...

In recent years, boundary scan has transformed itself. JTAG started more than a decade ago as a simple structural interconnect test technology. It now is a foundational embedded infrastructure capable ...

Samtec is releasing a variety of board-level and cable connector systems for JTAG applications, which are currently shipping in volume quantities, says the interconnect manufacturer. The Samtec JTAG ...

Gowin GoBridge is a family of bridging chips that convert a USB interface to different serial and parallel busses. “The GWU2X family enables conversion between USB and four peripheral interfaces: JTAG ...
