This guide explores how to leverage JTAG debugging with LiteX for RISC-V CPUs such as VexRiscv-SMP, NaxRiscv or future VexiiRiscv CPUs which are commonly used within LiteX SoCs/projects. We'll look at ...

Intel responded to a claim about hackers gaining hardware-level access to PCs sporting its sixth- and seventh-generation processors. The claim was made during a presentation at the 33rd annual Chaos ...

The debugging interface is JTAG (Joint Test Action Group), a debugging framework that has been included for many years with Intel chipsets. JTAG works under the software level, allowing engineers, ...

[Joe Grand] has come up with a tool which we think will be useful to anyone trying to hack a physical device: The JTAGulator. We touched on the JTAGulator briefly during our DEF CON coverage, but it ...

Abstract: As a general interface for chip system testing and on-chip debugging, JTAG is facing serious security threats. By analyzing the typical JTAG attack model and security protection measures, ...

Abstract: The IEEE Std. 1149.1, also known as JTAG, defines a serial interface to access test-dedicated logic embedded in integrated circuits, although it is also being used as an FPGA programming ...

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 ...
