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 ...

[Matt Evans] was running up against the common programming gotcha caused by disappearing parallel ports. For years he had used a JTAG parallel cable when working with FPGAs but recently realized he no ...

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 ...

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 ...

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.

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 ...

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 ...

The semiconductor industry has been deeply influenced to spur innovations, owing to the expansion of IoT, AI, and wireless communication in the market. It is essential to shape these innovations into ...

The 2nd Role of JTAG – CPU Core Access for Software/Hardware Debug Given that the CPU processor core is now hidden from observation or control by integrated caches in the core, by local on chip busses ...
