In the previous articles, we covered in great detail: We’ve seen how we can create our own nodes, we’ve seen the supported property types, we know what bindings are, and we’ve seen how to access the Devicetree using Zephyr’s API. In this fifth article of the series, we’ll look at how Devicetree is used in ..read more

In the previous article of this series, we briefly touched on how files written in Boundary Scan Description Language (BSDL) describe the structure of the boundary scan chain and the instruction set. In this article, we will examine this language’s syntax more closely before seeing how files are leveraged in JTAG testing in the next article ..read more

Here are the articles, videos, and tools that we’ve been excited about this March ..read more

In the third installment of this JTAG deep dive series, we will talk in-depth about JTAG Boundary-Scan, a method used to test interconnects on PCBs and internal IC sub-blocks. It is defined in the IEEE 1149.1 standard. I recommend reading of the series to get a good background on debugging with JTAG before jumping into this one ..read more

The ELF object file format is one of the most commonly used today. Most build systems provide an output to this format, and ELF is commonly used to output coredumps. The format varies in subtle ways for 32-bit and 64-bit targets though, which can present problems for tools supporting both. This post will highlight the main differences and is intended as a quick reference for these differences ..read more

In this second part of a JTAG deep-dive series, we take an in-depth look at interacting with a microcontroller’s memory and engaging with the processor core and debug registers. While the use of JTAG in testing is fairly standardized when it comes to debugging, each processor architecture has its unique nuances. With that in mind, this article will focus on debugging using JTAG on the ARM Cortex-M architecture, specifically with the STM32F407VG microcontroller ..read more

: For each supported type, we’ll create a corresponding and look at the generated output to understand how it can be used with Zephyr’s Devicetree API ..read more

In this second article of the “Practical Zephyr” series, we’ll explore the by looking at the logging option in Zephyr. We won’t explore the logging service as such in detail but instead use it as an excuse to dive deep into . Finally, we’ll create our own little application-specific ..read more
